Electric Bike Factory Introduces How To Avoid Electric Bike Controller Failure

What are the common faults of electric bike controller introduced by Electric Bike Factory ?

1. The riding noise of the electric bicycle is large and the speed becomes slower with load. After the car is stopped, the car can not start at zero. It can only run normally after the motor is turned.

Diagnosis and maintenance: This is a symptom of motor phase loss. Now the controller is mostly intelligent, and it will jitter at zero start due to phase loss. This may be caused by the damage of the motor Hall, and another possibility is that a certain phase circuit inside the controller has a problem. First, carefully check whether there is any problem with the connection line. If the Hall and connection lines are tested normally, then the internal components of the controller have failed, please replace the controller!

2. The electric vehicle is energized and does not work hard to implement, and it makes a “thumping kick” sound when it is implemented.Diagnosis and maintenance: In this case, the motor wire is short-circuited due to the contact of the virtual connection. You can unplug the three thick phase wires of the motor, and the laborious phenomenon disappears, indicating that the controller is broken, please replace it. If it is still difficult to implement, the problem of the motor may be caused by the short circuit and burnout of the motor coil.
