Abstract
A control method for an electric motor, an electric motor, and a computer-readable storage medium are provided. According to the method, in a current control cycle, a first theoretical sector corresponding to a voltage vector of an electric motor is determined; in the previous control cycle of the current control cycle, a first sector corresponding to the voltage vector is obtained; a target control cycle in multiple historical control cycles which precede the current control cycle is determined, and an interval duration between the target control cycle and the current control cycle is determined; a target sector corresponding to the voltage vector in the current control cycle based on the first theoretical sector, the first sector, and the interval duration is determined; and a corresponding driving signal based on the target sector is generated, and the electric motor is driven to operate based on the driving signal.
