Title: MOTOR CONTROL METHOD, MOTOR CONTROL DEVICE AND ELECTRIC BICYCLE
Abstract:
A motor control method, a motor control device and an electric bicycle. In said method, a microcontroller is used for acquiring one or more signals of a power drive circuit current signal, a pedal torque signal, and a motor rotation speed signal, and, according to changes in the acquired signals, for outputting a control signal to regulate the motor. By monitoring change in the power drive circuit current signal, the pedal torque signal and the motor rotation speed signal, the motor can be controlled accurately, avoiding continued high-speed rotation of the motor due to motor drive belt delay at the moment when the clutch is disengaged, thereby preventing the motor from screeching due to no load, prolonging the service life of the motor while providing the user with a better biking experience.
