Abstract

The invention provides a motor control method, which comprises the following steps: acquiring operation parameters of a motor, the operation parameters comprising current I, resistance R and rotating speed n; acquiring the temperature rise rate of the motor according to the operation parameters; obtaining a motor temperature change curve T (t) according to the temperature rise rate; and comparing the current operating temperature of the motor with the motor temperature change curve T (t) so as to control the motor to send out an early warning signal or control the motor to operate normally. The problem that motor aging is accelerated due to lagging of motor heat detection in the prior art is solved.
