Abstract

See full text

A method for controlling heating of a motor and a related controller are provided. The method includes: obtaining a heating target temperature value; determining, based on the heating target temperature value, a heating motor that needs to generate heat from a plurality of motors of a multi-motor drive system and heat generation power of the heating motor; and sending a first control instruction to the heating motor. The first control instruction is used to respectively input harmonic currents to three phases of windings of the motor, so that the heating motor generates heat based on the heat generation power. According to the application, the heating target temperature value is obtained, and the quantity of heating motors can be flexibly controlled to generate sufficient heat generation power.
