Abstract
A method for protecting a motor from overheating, includes: running a motor in a given parameter P and detecting a real-time temperature R of the motor; comparing the real-time temperature R with a plurality of set temperatures, the plurality of set temperatures including an overheating protection temperature Rm, shutdown temperature Rmax and recovery operation temperature Rmin, Rmin<Rm<Rmax; according to a comparison result, controlling the motor to operate at an initial current value I, or operate in a reduced current value with respect to the initial current value I, or stop running; and when the real-time temperature R meets the condition: Rm<R<Rmax, running the motor in an overheating protection mode, where the motor operates in a current value I lower than the initial current value I, and the current value I decreases with the increase of the real-time temperature R.
