The electric motor of the electric vehicle is overheated and runs weakly:

The reasons for this failure are:

1. Long-term overload, magnetic field demagnetization

The solution is to re-magnetize or replace the permanent magnet of the motor.

2. The brake is powered off and the switch does not work

The solution is to adjust the interlocking performance of the brake power-off switch.

3. Long-term uphill power loss

The solution is to recharge the battery in time

4. Short circuit damage to motor windings

Solution: repair or replace the motor.
