Zusammenfassung:A method for protecting a motor from overloading includes: acquiring a present effective value of a phase current of a motor; performing time integration on the present effective value of the phase current, to obtain a first integral value; obtaining a first threshold; performing overload detection according to the first threshold and the first integral value; determining a target limiting current for operation of the motor if an overload occurs; and controlling the operation of the motor based on the target limiting current.
