Abstract

This application discloses a method, apparatus, device, storage medium, and product for adjusting the torque accuracy of a motor. The method includes: determining a first desired torque and back electromotive force (EMF) corresponding to each speed within a preset speed range, a second desired torque corresponding to a preset operating condition, and an initial torque compensation coefficient corresponding to each first desired torque; determining the first torque accuracy corresponding to each speed based on the first desired torque and back EMF corresponding to each speed; calculating the second torque accuracy corresponding to each preset operating condition based on the second desired torque and back EMF corresponding to the speed of each preset operating condition; weighted summing of the first torque accuracy and the second torque accuracy at the same speed to obtain the comprehensive torque accuracy corresponding to each speed of the motor; and correcting the initial torque compensation coefficient based on the comprehensive torque accuracy to obtain the adjusted torque accuracy of the motor.
