[0002] Low-speed electric vehicles are now a very popular means of transportation, whether it is a low-speed 2-wheel bicycle, 2-wheel electric motorcycle, 3-wheel electric truck, 3-wheel low-speed passenger car, 4-wheel low-speed car, 4-wheel low-speed cleaning Cleaning vehicles, 4-wheel low-speed wheelchairs and 2-wheel low-speed cargo carts are widely used, but due to the characteristics of brushless controllers and brushless motors without traditional commutators and carbon brushes, brushless The commutation of the motor relies on the internal Hall phase sensor of the brushless motor to monitor the phase angle of the motor, and sends the angle signal to the brushless motor controller to identify the current phase angle of the brushless motor, so that the brushless motor rotates. If the Hall phase sensor of the brush motor is damaged, the current phase angle of the motor cannot be recognized, and the brushless motor controller cannot recognize the current phase of the motor, so that the brushless motor controller cannot commutate the motor. Under the current condition, the current of the phase line of the motor is too large, so the protection stops the output, and the maintenance time is longer
