Document Type and Number:
WIPO Patent Application WO/2016/041142
Kind Code:
A1
Abstract:
Provided are an alarm determining method and apparatus for stalling of a motor, and an electric appliance. The method comprises: acquiring a first active power of a motor, and acquiring a second active power of a phase resistor of the motor; and when a continuously satisfying time of a stalling determining condition reaches a preset time, stopping power supply to the motor, and prompting stalling information, wherein the stalling determining condition is that the first active power is lower than a stalling power threshold of the motor, and the second active power is greater than or equal to a stalling power threshold of the phase resistor of the motor. In this way, whether stalling occurs on a motor is detected in real time; and if the stalling occurs, the power supply to the motor is cut off in time, and the stalling information is output in time to prompt a user to check the motor or replace the motor in time.
