Motor control method and apparatus, device, and storage medium

A motor control apparatus, comprising:

• a first acquisition module, configured for acquiring a rotational speed error of a rotor of a motor corresponding to a current moment as a first rotational speed error;
• a second acquisition module, configured for acquiring a speed compensation value for the rotor according to a speed drop graph which is preset, wherein the speed drop graph represents a graphical representation of speed versus time when a rotational speed of the rotor drops;
• a calculation module, configured for calculating an electric current compensation value according to the speed compensation value and a speed-current mapping model which is preset;
• a third acquisition module, configured for acquiring an electric current reference value corresponding to the current moment, wherein the electric current reference value is an electric current value for controlling the rotational speed of the rotor;
• a first control module, configured for controlling the motor according to the electric current compensation value in response to the first rotational speed error being greater than a preset error;
• and
• a second control module, configured for controlling the motor according to the electric current reference value in response to the first rotational speed error being less than or equal to the preset error.
