Motor Encoder
7ćMotor check
Connections with the controller are normal, and when you tap the accelerator, you find that
the car doesn't move, or it jitters at a very slow speed. The motor encoder is normal,
but the motor phase sequence is not correct. It needs to change the U V or V W phases of the
motor . Or motor encoder abnormality, such as encoder power supply abnormality,
disconnection, poor terminal contact, terminal sequence error, encoder damage.
