Abstract
Embodiments of this application provide a torque obtaining method and device, a motor controller, and a readable storage medium. The torque obtaining method includes: obtaining a rotation speed of a motor; obtaining a current of the motor; obtaining a flux linkage of the motor; determining an electromagnetic torque of the motor based on the current and the flux linkage; and inputting the rotation speed and the electromagnetic torque into a preset status observer, and obtaining an observed value of an actual output torque of the motor, where the observed value is output by the status observer. The obtaining method is intended to obtain the actual output torque effectively, simply, and accurately.
