The rear wheel of the battery car can be idled, and it can t turn when it lands, what s going on?

The rear wheel of the battery car can be rotated when it is idle, but it cannot be rotated when it lands because:

1. The controller is bad or the phase is wrong or short-circuited, and the phase is wired.

Heating, melting of the insulating skin, poor phase contact.

2. The electronic switch of the brake handle does not return, and the brake signal line and the rotary handle signal line are worn out and short-circuited, or the brake pads.

Damaged or the screws on the brakes have fallen off.

3. The hall is broken, and the controller can't find the angle of the tire and it won't work. Do not push the cart to the repair shop while it is energized, otherwise the motor will burn out. If you push it strongly, it is easy to burn the Hall element in the motor.

Classification of electric vehicle controllers.

1. Separation.

The so-called separation refers to the separation of the controller body and the display part. The latter is mounted on the handlebar, while the controller body is hidden in the body compartment or electric box. In this way, the connection distance between the controller, the power supply and the motor is shortened, and the appearance of the car body appears simple.

2. All-in-one.

The control part is integrated with the display part and is housed in a delicate special plastic box. The box is installed in the center of the handlebar, and the panel of the box has a different number of small holes, the hole diameter is 4-5mm, and the transparent waterproof membrane is applied to the outside. A light-emitting diode is provided at the corresponding position in the hole.

to indicate speed, power, and battery power.

Maybe one of the things inside called Hall is brokenWhen you take it out, it looks like a transistor.

The master who repaired the car here in Chengdu called that thing Hall. My battery car broke down once, and that's your case. Inside the rear wheels of the car, inside the motor. It costs about 30 pieces to change 3 pieces.

Common faults of battery cars.

The motor rotates and stops.

1. The voltage of the battery will turn and stop when it is in the critical state of undervoltage.

2. This kind of failure will also occur if the battery connector is in poor contact.

3. The line of the speed control handle should be broken and the brake power-off switch is faulty.

The rear wheels of the battery car are idling off the ground, but they do not rotate when they land, first check that the battery is and there is enough overcurrent but the battery is in good condition, some electric vehicles mark you with dry batteries, he is actually a lead-acid battery, and it is also necessary to maintain a certain amount of maintenance, you open the upper cover of the battery with a syringe and add 30 ml of distilled water to 2 hours and then charge it to resume normal use.

In this case, there may be a problem with the bearing. I hope you go get it repaired.

It may be that the power output is not enough, and there is a problem with a part of the circuit, so it is recommended to check it at the place where the electric car is repaired.

Summary. According to your description, the reasons are as follows: 1. Brake power failure (such as brake cable disconnection, brake switch does not return, etc.) In this case, turn on the power and the rear brake light stays on. ）

2. The speed control handle is faulty, (check whether the speed control handle plug is connected reliably.) The 3-wire can also be directly shorted to the handle (generally red) and the signal line (generally green), and the motor should be rotated after the shorting).

The electric car is idling, and the person sits on it and does not move, and the motor is turning the wheels without turning, what is going on???

According to your description, the reasons are as follows: 1. Brake Feng Bijing power off (such as brake cable disconnection, brake switch does not return, etc.) In this case, turn on the power and the tail brake light will always be on.

2. The speed control handle is faulty, (check whether the speed control handle plug is connected reliably.) The 3-wire can also be directly shorted to the handle (generally red) and the signal line (generally green), and the motor should be turned after shorting).

1. Turn the electric door and twist the handle to see if the indicator light is undervoltage. 2. Is the shaking motor very heavy? Shen is the controller is damaged and withered.

3. Open the controller to disassemble the brake and disconnect the wire, twist and turn the motor to turn the brake and power off switch, and eliminate them one by one. 4. Check whether the head of each plug-in state is loose, falling off, or imaginary. 5. Try a new controller and turn the handle.

<> please check the above reasons one by one.

I can use it with a different motor, but I want to use the original motor for more power.

<> the electric motor has a lot of power, the electric car has a lot of power, the speed is fast, and the uphill is easy. The 60V motor has a speed of about 40 kilometers per hour at 800W. 60V1000W at a speed of about 50 kilometers per hour.

The speed of the solo uphill is about 40-45 kilometers per hour. For example, it is easier to make Hunger Fruit 72 V1000W faster. Therefore, the power of the motor should be determined by each individual.

The power is high, you need to run fast, but the relative range will be short, the power is small, the trotting is slow, but the cruising range is longer. Hope it helps.

<> can be purchased according to your individual needs.

2 possibilities. 1.The battery life is up, or the charge burns out. Look at it is full, and when it accelerates, it runs out of power. People ride up and turn on the speed regulation to quickly see if the power meter is out of power, if it is out of power, the battery is broken.

2.The controller is broken, and it can turn when it is empty, but it is also very slow, and it doesn't move when riding. It's good to change the controller or fix the controller.

The cracking ability of the motor is almost zero, and the possibility of the speed control handle being broken is also zero.

If I'm helpful to you, remember to light it up, thank you!

Hello! If the battery car appears in the state of the rear wheel suspension can rotate normally, and can not operate normally when landing, the cause of the bending is quietly caused by the damage of the Hall components inside the motor, you can replace a dismantling of the rear wheel motor, take it out to see that thing like a triode, the local car repair master called that thing Hall. My battery car broke down once, and you buried it in this situation.

Inside the rear wheels of the car, inside the motor. It costs about 50 pieces to change 3 pieces. I hope mine can help you, I wish you a safe journey and a happy life!

The wheel behind this one sometimes turns and sometimes it doesn't, if this happens. If this phenomenon occurs, because there is a motor in the back of the chain, it is necessary to disassemble and check the motor inside and the coil of the ridge punch, to see if there is a problem, whether it is burned out is a specific inspection, and it is also necessary to check the line to see if it is normal to be energized, including the power of the battery, including the controller of the electric car, to see if there is a problem. The circuit board inside this one is burned out to see if it is burned, and these are all things that need to be checked.

1. The controller is bad or the phase is wrong or short-circuited.

back, the phase line heats up.

The insulating skin is melted, and the phase wire contact is poor.

2. The electronic switch of the brake handle does not return, the brake signal line and the turn signal line are worn out and the tie is short-circuited, or the brake pad is damaged or the screw on the brake is lost.

3. The hall is broken, and the controller can't find the angle of the tire and it won't work. Do not push the cart to the repair shop while it is energized, otherwise the motor will burn out. If you push it strongly, it is easy to burn the Hall element in the motor.

Maybe one of the things called Hall inside is broken, and when I take it out, that thing looks like a transistor, and the master who repairs the car here in Chengdu calls that thing Hall. My battery car broke down once, and that's your case. Inside the rear wheels of the car, inside the motor. It's only 30 yuan for 3 pieces.

1. The first thing to consider may be the brake pads.

If it is too tight or the brake pads come off, relax the brakes completely. After inspection, the brake rocker arm returns flexibly. But after relaxation, the rear wheels are still very tight, which means that it is not a problem with the brakes.

2. Riding an electric car, the rear wheel suddenly locks up, and if you don't go, you can't push it, and the rear wheel shakes and shakes. When the power is on, the rear wheels are locked when the handlebar is turned on, but the electric car is normal without load.

Cause: Bad controller or phase wrong or short circuit, phase wire.

Heating, melting of the insulating skin, poor phase contact. The phase wire is short-circuited, and the wheels are difficult to push; The electronic switch of the brake handle does not return; The brake signal line and the handle signal line are worn out and the tie is short-circuited; or damaged brake pads. Is it that the screws on the brakes are missing.

3. Whether the motor bearing (or motor magnetic cylinder) is damaged.

4. Whether the controller is damaged (Note: If the controller is damaged, the rear wheel will not lock).

5. The rear wheel anti-theft lock of the electric vehicle is self-locking or has been locked and has not been opened.

If the rear wheel does not move, it is generally the controller that is damaged, and it is recommended to check the following points:

The rear brake is not locked.

The rear flywheel is not loose and stuck.

Whether the motor bearing (or motor cylinder) is damaged.

If there are no problems with the above points, then it is possible that the position of the back spiral has dropped or broken.

Please check the following:

The rear brake of the electric car is not locked.

Is the rear flywheel of the electric car loose and stuck.

Whether the motor bearing (or motor cylinder) is damaged.

There is no damage to the controller (Note: If the controller is damaged, the rear wheel will not lock) (if it helps you, please set "Positive", thanks!) ）

First see if the fuse is broken, then see if the voltage of the rotary handle has changed, then see if the motor hall sensor is broken, and finally see if the controller is good. Before doing these jobs, first check whether the battery has electricity and whether the wiring is good.

First, when there is no electricity, find a place to charge;

Second, if the engine is broken, find a place to repair it;

Third, if the bearing is broken, find a place to repair it;

Fourth, the rear lock is not opened, check it.

Let's repair the car, it is estimated that there is a problem with the rear wheel bearing.

It may be that the magnet block in the motor has fallen off and is stuck. There are a lot of magnets in the motor, and you can't drop one of them. I've had this situation before.

The normal situation is that the position of the rear spiral is dropped or broken, and the difficulty and cost of this repair are not high.
