What is the situation when the motor of an electric vehicle does not ride for a long time?

Prop up the big ladder and turn the wheels by hand, if it can run freely, it means that the battery has no electricity, and as usual, the battery starved to death. You can go to the repair department and ask them to repair it, and then use the charger on the car to charge it.

This is obviously the battery is dead, not used for a long time, the battery needs to be charged, if you don't charge, you will starve to death, charge it first.

The motor of the electric vehicle does not rotate and is related to the failure of the controller MOS tube, the short circuit of the motor phase line, the failure of the motor hall and the failure of the speed control handlebar, etc., in addition, when the electric vehicle battery is dead, the motor will not rotate. If you want to know whether the motor is damaged, you can judge it according to the following performances, such as the car is weak uphill, slow starting, unsmooth rotation when suspended and odor, etc., which are common faults of motor damage.

What is the fault of the electric vehicle motor not turning?

If the motor does not rotate, the electric car cannot be used normally even if there is electricity. At this time, you can first see if the electric car has electricity, if there is electricity, it is most likely a failure. Generally speaking, when the controller and speed control handle fail, it will cause the motor to be abnormal.

In addition, problems with the motor itself, such as a malfunctioning Hall sensor or a short circuit in the phase of the motor, can also cause the motor of the electric vehicle to not rotate. At this time, you can send the electric car to the maintenance department for maintenance to see if there is a problem.

The performance of a broken electric vehicle motor.

Weak climbing, foul smell of the motor, slow starting speed or no rotation, etc., are all caused by motor failure. If you want to know what is wrong with the motor, you can first twist the handle to see if there is a clicking sound when the handle rotates, if there is a sound, it may be caused by damage to the magnets or bearings inside the motor. In addition to turning the handlebar, you can also disassemble the place where the motor is placed, use the Hall detector to detect whether the Hall sensor is abnormal, and see if the line is sticky.

Summary. The reason why the electric vehicle has electricity but the motor does not rotate is due to damage to the brake handlebar, damage to the speed control handlebar, damage to the motor and the controller. It is recommended that you go to a garage for proper maintenance.

The electric car has electricity but the motor does not turn.

The reason why the electric vehicle has electricity but the motor does not rotate is due to damage to the brake handlebar, damage to the speed control handlebar, damage to the motor and the controller. It is recommended that you go to a garage for proper maintenance.

The solution for the motor of the electric vehicle does not rotate.

The solution for the electric vehicle motor not to rotate: 1The first case is the simplest, the fuse blows.

In this case, the motor is OK after replacing the fuse, and the repair cost of this fault is also minimal. 2.The second case is that the power switch is broken, replace the power switch.

Judgment method: turn on the power switch, use the multimeter ohmic file to measure the resistance between the input end and the output end of the power switch, if the resistance value is zero, it is normal, if the resistance value is infinite, the power switch is bad, and the power switch should be replaced. 3.

The third is that the hall turn is broken. The specific diagnosis method is to use the multimeter DC voltage to measure the output voltage of the green line at the output end of the handlebar, if there is a voltage output, the handle is normal, if there is no voltage output, the handle burns out, and the handle needs to be replaced. 4.

Bad controller. Use the multimeter DC voltage level to measure the red wiring at the output end of the controller (the plug of the adapter wire), if there is a voltage output of about 5 volts, the controller is normal, if there is no voltage output, the controller is burned out, and the controller needs to be replaced. 5.

Each connector of the motor is loose, and each connector is checked again. It may also be that the battery box is not in place when it is placed in the frame, and the contacts are not in good contact.

The single-phase asynchronous motor can only be started by external force, but it cannot be pushed by human force. Therefore, in addition to the working winding, the stator winding of the motor must also have a starting winding. When the two windings differ by 90° in space, and then two currents with a displacement difference of 90° are introduced into each other, a rotating magnetic field is generated.

Single-phase asynchronous motors generally use capacitor starting and operation mode. When the capacitance is reduced or there is no capacitance, it cannot start on its own. As you said, touch the roulette wheel with your hand before it turns, which is activated by external forces.

Solution: You open the back case of the washing machine, and you can see a cylindrical capacitor under the washing machine, and you remove it. Buy a new one according to the voltage backvoltage value and capacitor capacity marked above, and the problem will be solved after the new installation.

Generally, the starting capacitor is 500 volts 5-10 microfarthic.

For the reason of the slow turn:

One. For single-phase capacitor motors: Workaround:

1.Check the mechanical parts first. 2.

Check the capacitance. The reason for this is that the capacitance capacity becomes smaller. 3.

Check the winding. A: It's not easy to check. It can be disassembled to check whether the winding has burned paste and other phenomena.

Two. For series motors:1Look at the transmission mechanism. 2.Check whether the stator and rotor are swept. 3.Check the stator and rotor for short circuits. A slight short circuit is not easy to check. Parts can be replaced.

There are two types of general single-phase motors, of course, there are shaded pole motors and so on. Generally not commonly used. Let's not talk about it.

The first thing to check above is whether the wiring is loose. Often a lot of slow motors are because the wiring is loose, and it looks like it is also connected. However, if the connection is not tight, it will cause the rotation to be slow.

Don't just check the wires of the motor, the power supply or the upper level sometimes have to check as well.

There are three main reasons for this:

First, the problem of power copying, such as fuse burning, circuit breaker damage, control line failure to make contact.

The DAO device is not engaged or the contactor is damaged;

Second, the motor itself, such as coil phase short circuit, grounding, bearing jamming, rotor breakage, etc.

3. The load is too large, resulting in overload or even failure to start the motor.

It can be poured with hot water and thawed with hot water. At ten o'clock, it may be water, and you can use a hair dryer to heat and dry. There is also the possibility that the friction between the rotor and the stator causes difficulty in rotation, in which case the motor needs to be disassembled.

There are three main driving modes of electric vehicles: one is in-wheel drive, one is mid-mounted, and one is suspended. The electric driving on the market is dominated by wheel hub drive, and wheel hub drive is better than rear wheel drive, and front-wheel drive performance is relatively poor.

The location of the battery.

From the perspective of the balance of the whole vehicle and the convenience of getting on and off the car, it is better to place the battery in the position of the frame inclined pipe or riser, and the battery configured is basically an economical lead-acid battery.

Most electric cranes use 36V12Ah lead-acid batteries; The 24V12Ah battery has fewer choices due to its short driving range.

The motor is flooded!

Turn on the motor, pour the water out, then use a hair dryer to dry the motor coil, and then replace the bearing!

There are two places where the water enters the motor, one is flowing along the motor line, and the other is the water entering from the position of the motor shaft!

First loosen the brake and try it, my judgment is the problem of the brake, I have encountered a lot of similar problems, I hope my reminder can help you, it is your brake target line accidentally entered the water in the rain, due to the weather caused by the brake tightening, if it is still like that, it means that the motor is water.

1. The brake handle, if it is an electronic brake handle, the motor is not working, there are two kinds of electronic brake handles, one is Hall type, such as oh44E, which is a switch signal, and the other is a micro switch. That is, the acceleration motor does not rotate when braking.

2. Handlebar: Linear Hall is used inside: oh49E, etc., and the handle is generally not accelerated (no turn), or directly accelerated (flying) when the handlebar is broken.

3. The motor hall is broken (no output signal), it is recommended that non-professionals do not open it, especially do not pry it open, because it will destroy the waterproofing of the motor, etc., if it must be opened, it must be opened (because there is a strong magnetic force in the motor, and the inertia is used to open it at one time) The general repair of the bicycle will be opened, and it is best to find them.

After opening, you will see that there are 3 halls on the coil, generally switch halls, such as: OH44E, OH41, or OH41F, etc. It is best to change all 3 of them.

4. The controller is broken! It's not worth repairing, and it's generally replaced directly. It's best to find a match!

If the motor of the new energy electric vehicle can rotate, but the car can not drive, then it is mainly because the output shaft gear of the motor, or the reducer gear or differential gear is worn, resulting in your vehicle can not be driven. After dismantling, look at the internal gear **broken or worn**, and directly replace the corresponding gear to solve the problem.
