If the motor of the electric car is broken, will it affect the battery?

What is the situation? If the motor is broken, there are several manifestations: one is that there is no reaction, that is, it can't be turned on; The second is that the twisting handle is shaking, and it can't be seen or ridden weakly, and it basically can't be opened; The third is that the motor feels less energetic and hot than in the past.

It's very powerful, and it will cost more electricity at this time. So, at best, it can be driven more power-intensively. Thank you.

It will cause the rated voltage and current to be substandard, it will be difficult for the electric vehicle to start, and the voltage will drop when accelerating. When fully charged, the driving distance is significantly shortened compared with before, and the battery car shows that the number of charging compartments is unstable. If you charge when there is no power, the charger will show that it has been fully charged after a while, etc.

If one battery is broken, it will definitely have an impact on others, and it will cause other batteries to be damaged at an accelerated pace, and they will generally be replaced all. It's like four people running together, but their feet are tied together, and that running together may not perform as well as the worst one because of consistency issues. All the changes should also be replaced in the same batch, and it is best to connect them with serial numbers, so that the performance will be much better.

Don't just change one, the overall life expectancy will drop dramatically.

You can find a suitable electric furnace wire in parallel at both ends of the multimeter, and measure the voltage of each battery with a voltage level, the low voltage is a bad battery, the principle is to see the high current load capacity of the battery, that is, the reason why the acceleration voltage drops greatly.

The general lead-acid battery, under normal use, has a service life of about one and a half years, and it should be used more properly, without long-term high-power discharge or power loss. If you usually don't pay much attention, often accelerate sharply or the load is too large, and the damage to the battery can no longer be repaired, then you can only replace it, don't buy second-hand ones, many of them have been repaired, and the performance is very unstable.

First, the reaction of the electric car breaking.

1.After suspension, the motor seems to be blocked and cannot rotate smoothly, suddenly fails to start, the motor rotates, the uphill is weak, shaking or slow starting, the motor stinks, etc. If the motor is weak, check the hall, controller, motor coil, hall wire on the handlebar, etc.

If there is no problem with the motor and Hall wire, there may be a problem with the controller.

2.When the motor fails, it will not be able to turn with your hands, and the magnet of the motor will fall off, and it will not rotate when it turns, so you will touch the ground if you sit on it. Electric vehicle.

An electric motor refers to a drive motor used in an electric vehicle. Depending on the environment and frequency of use, the form is different. Different types of motors have different characteristics. At present, permanent magnet DC motors are widely used in electric vehicles.

Second, the maintenance method of the motor.

The use environment should always be kept dry, the surface of the motor should be kept clean, and the air intake should not be blocked by dust, fibers, etc. When the thermal protection of the motor is running continuously, it should be found out whether the fault is caused by the motor or overload, or the setting value of the protection device is too low, and it can only be put into operation after the fault is eliminated.

3. How to judge the electric vehicle motor.

Whether it's broken or not. 1.Disassemble the seat bag, find the connector between the controller and the motor, disconnect the plug, and check if the motor hall is working properly with the Hall detector.

Gently turn the rear wheel, and find that one indicator light or two indicators keep on or off, indicating that the hall is damaged and needs to be replaced.

2.There is adhesion or short circuit at the junction of the motor line and the control line. Then find the place where the line is stuck, disassemble it and wrap it with tape, and re-debug. If it is normal, it means that the problem is adhesion.

3.When the knob turns, the wheels rattle and cannot turn. It could be the magnet inside the motor.

or the bearing is damaged, resulting in a large load and slow running speed. It is necessary to turn on the motor for further inspection. Hall sensors.

If the motor is burned out, the car will not run.

4.If the vehicle is overloaded and suddenly cannot drive, it will be gently pushed and will not shake, and if you are close to the motor, you will smell a very bad smell, indicating that the motor winding wire is burned out and the motor needs to be replaced.

The electric vehicle suddenly cannot drive, is in a paralyzed state, and the magnet of the motor will fall off and cannot rotate, in addition to the motor can not run smoothly, resulting in the electric car can not start or have no strength to go uphill.

Electric vehicles will not be able to drive, car parts will be damaged, battery performance will be reduced, electric vehicles will consume electricity very quickly, and the service life of electric vehicles will be shortened.

There is no way for the electric car to drive, it cannot rotate smoothly, the electric car has no power, the motor parts of the electric car may be relatively loose, and the electric car will be very laborious when there is no power when going uphill.

The uphill slope is weak, there is no way to start normally, the stability is very poor, there is a shaking situation, and the speed of starting is very slow.

After running, you may decide to massage your own muscles to relax, or properly perform some stretching movements to soothe your hand muscles, but don't stop immediately after running, or slowly transition to jogging and then can't, adjust your breathing rate to slow down.

Will the battery car motor be broken and it will cost electricity: Yes.

'That's right, my previous battery used to be used for more than three years and a month, and I felt that the power was draining very quickly': the battery and the motor were fine at that time.

After using it for more than three years and a month:

1-I feel that the power consumption is very fast: the battery has been used for more than three years and a month, and it has basically reached its lifespan, and if it is the reason for the battery, it should be restored to the 'original state' after replacing the new battery.

2-After changing, I feel that I still can't run far, the car will make a clicking sound when it starts, and then there will be no more, and there is a feeling that the rear wheel is shaking when the road is flat, what is the reason: if the motor rotor, scratching stator, and motor bearing problems will cause 'insufficient power' and fast power consumption.

Will the battery car motor be broken and it will cost electricity: Yes.

The motor bearing is seriously worn, and the motor should be repaired and replaced to solve the problem of power consumption, especially the damage of the bearing beads, if the motor bearing causes the motor to sweep the chamber, it will consume a lot of current until the motor burns out.

The range of battery cars is not very long, and it cannot be compared with gasoline-burning motorcycles. It is difficult to judge the reason only based on your complaint, and you need to take a look at the car's condition on the spot. It is recommended that you go to the car dealer to find the master to check on the spot.

The motor is rusty due to water ingress and cannot be rotated by hand. The motor hall is bad and does not turn. The motor magnet falls off, and it does not rotate from time to time, so sit on it and play the gen.

Motor maintenance method:

1. The use environment should be kept dry, the surface of the motor should be kept clean, and the air inlet should not be hindered by dust and fibers.

2. When the thermal protection of the motor is continuously activated, it should be found out whether the fault comes from the local rise refers to the motor or the overload or the setting value of the protection device is too low, and the fault can be put into operation only after the fault is eliminated.

3. Good lubrication of the motor during operation should be ensured. The general motor runs for about 5000 hours, that is, the grease should be supplemented or replaced, and when the bearing is found to be overheated or the lubrication deteriorates, the hydraulic pressure should change the grease in time. When replacing the grease, the old lubricating oil should be removed, and the oil groove of the bearing and bearing cover should be cleaned with gasoline.

4. When the life of the bearing ends, the vibration and noise of the motor operation will increase significantly, and when the radial clearance of the bearing reaches the following values, the bearing should be replaced.

Electric vehicle motorsIf it is broken, it will tremble and it will not be able to rotate by hand, the motor magnet will fall off, and it will not rotate from time to time, and it will sit on it and play the gen. Electric vehicle motor refers to:Electric vehicle. of the drive motor. The form varies depending on the environment in which it is used and the frequency of use.

Different forms of motors have different characteristics. At present, permanent magnet DC motors are commonly used in electric vehicle motors.

Maintenance method of electric eggplant Tuanchang machine:The use environment should be kept dry frequently, the surface of the motor should be kept clean, and the air inlet should not be hindered by dust, fibers, etc. When the thermal protection of the motor is continuously in action, it should be found out whether the fault comes from the motor or is overloaded or the setting value of the protection device is too low, and the fault can be put into operation only after the fault is eliminated. Or Ming.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, I am your exclusive lack of rolling technician Cui Zhiqiang, attentive, careful, dedicated to answering your car questions, for you to find the corresponding solutions and solutions to the problems! The broken motor of an electric vehicle can be divided into circuit problems or mechanical problems, the no-load current is too large, the load of the motor is too large, and the speed is too fast and too high. The motor is overheating.

There was a collision with the internal structure of the motor.

If the electric vehicle motor is broken, it will enter the water and rust, and it will not be able to turn by hand

1. The use environment should always be kept dry, the surface of the motor should be kept clean, and the vent should not be obstructed by dust, fibers, etc.

2. When the thermal protection of the motor is in continuous action, it should be found out whether the fault comes from the motor or overload or the setting value of the protection device is too low, and the fault can be put into operation only after the fault is eliminated.

3. In order to ensure the good lubrication of the motor in operation, the general motor runs for about 5000 hours, that is, the grease should be supplemented or replaced, and the bearing is found to be overheated or the grease deteriorates during operation, and the hydraulic grease should be replaced in time.

Introduction to motors. An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor squirrel cage closed aluminum frame to form a magnetoelectric dynamic rotation torque.

The motor is divided into DC motor and AC motor according to the different power sources, and most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the magnetic field speed of the stator of the motor is not synchronized with the rotation speed of the rotor).

The motor is mainly composed of a stator and a rotor, and the direction of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic inductance line (magnetic field direction). The working principle of the motor is the effect of the magnetic field on the current force, which makes the motor rotate.

Wait a minute. Hello, measure the voltage first, if the voltage is normal, close the switch, see if the voltage passes through the switch and the controller, if you measure a few lines of the motor, one of which will have a voltage, then the motor will turn on the line, if the motor does not turn, you have to disassemble the machine to check. The judgment of the electric vehicle motor is the degree of insulation of the motor and whether it is insulated and grounded.

Whether the resistance value of each variable speed resistance of the motor is normal. Whether there is any poor contact at the wiring. In terms of power supply, the motor heating caused by unstable voltage and so on.

Since the motor is sealed, if you want to fundamentally judge its quality, you need to use certain external tools, such as a swastika. In addition to the use of professional tools, it can also be judged from the appearance of materials and general properties. The above methods can be simply boiled down to:

One look, two listens, three touches and four tests. One look: look at the shell.

Motors with good outer plating generally have a brighter appearance, while refurbished machines are gray and dull. Then you can look at the motor trademark, generally larger manufacturers value the development of the brand will be marked, which is a manifestation of brand quality. Finally, you can see whether the motor has 3C certification, and the motor that meets the industry specifications will be more secure.

Second touch: touch the temperature. After the motor is stopped, consumers can use their hands to sense the temperature of the motor, the lower the temperature, the better the heat dissipation of the motor, and the better the performance.

Three listening: Listen to the motivation. During the test run, the consumer can check whether the power is sufficient when the load starts, and the power that is not abundant is likely to cut corners on the motor coil.

Fourth, detection: detection resistance. 1. Detect the quality of the AC three-phase motor, the 500V shake meter can be shaken, and the insulation resistance value of the line on the three binding posts to the motor shell can be shaken, and there is no short circuit to the ground above Europe.

2. Multimeter measurement: measure the resistance between the three phases of A, B and C, whether they are equal. The greater the difference in values, the worse the performance of the motor.

And the greater the power of the motor, the smaller the resistance! However, it cannot be 0 ohms for all three phases, unless it is a particularly large motor above 50kw, but this current electric vehicle application can be said to be none.

It is related, if the battery is not only used, it may be that the power of the generator motor is relatively high, and then the battery is not so durable, so you can see which one is faulty.

The battery of an electric vehicle is not durable, and it has something to do with the motor.

Generally speaking, the higher the battery voltage of an electric vehicle, the faster the speed; The higher the battery capacity, the longer the range of the electric vehicle, that is, the distance traveled on a single charge.

Similarly, the higher the power of the electric motor, the faster the speed, of course, if the current remains the same, the voltage of the high-power motor will be correspondingly larger.

Therefore, the relationship between the electric vehicle battery and the motor is that in the case of the electric vehicle equipped with the same battery, the high-power motor needs a larger voltage, and the current will become smaller, so the discharge time is longer, and the battery life is longer.

Therefore, when you buy an electric vehicle in the future, you should also look at the power of the battery and motor of the electric vehicle, of course, you must choose the model that meets the national specifications and standards.

Electric vehicle motor refers to the drive motor used in electric vehicles. Depending on the environment and frequency of use, the form is different. Different types of motors have different characteristics.

At present, permanent magnet DC motors are widely used in electric vehicles. Electric vehicle motors can be divided into brushed motors and brushless motors according to the form of motor energization. According to the mechanical structure of the motor assembly, it is generally divided into "toothed" (the motor rotates at high speed and requires gear reduction) and "toothless" (the motor torque output does not undergo any deceleration).

A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., stator winding) to generate a rotating magnetic field that acts on the rotor's squirrel cage enclosed aluminum frame to form a magnetoelectric rotational moment. Motors are divided into DC motors and AC motors according to the different power sources.

Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the speed of the stator magnetic field and the speed of the rotor are not synchronized). The motor is mainly composed of a stator and a rotor, and the direction of the forced movement of the wire in the magnetic field is related to the direction of the current and the magnetic induction line (direction of the magnetic field). The working principle of the motor is that the magnetic field exerts a force on the electric current, which makes the motor rotate.

The main symptom of a bad electric vehicle motor is that the electric seepage motor does not rotate, or the motor cannot rotate, or the motor makes abnormal noise, but it is normal to turn on the lights or whistle, so the electric vehicle motor may be broken.

Generally, in the event of a non-rotating fault, first check whether the peripheral circuit is open or whether the battery is dead. If not, then there is a problem with the motor, and it may be that your long-term use has caused the normal consumption of the motor carbon brush, and the resulting chain reaction has caused your controller to fail.

If the motor of the electric car is broken, it will happen that the motor cannot be rotated manually, and the magnet of the motor will fall, and it will not rotate if it turns, and you can be beaten if you sit on it. Electric vehicle motor refers to the drive motor used in electric vehicles. Depending on the environment and frequency of use, the form is different.

Different types of motors have different characteristics. At present, permanent magnet DC motors are widely used in electric vehicles.

The method of protecting the motor: 1. The use environment should always be kept dry, the surface of the motor should be kept clean, and the air inlet should not be hindered by dust, fibers, etc. 2.

When the motor thermal protection is continuously activated, it should be found out whether the fault comes from the motor overload or the setting value of the protection device is too low, and the fault can be put into operation only after the fault is eliminated.
