ELECTRIC MOTOR PROTECTION METHOD AND APPARATUS BASED ON TEMPERATURE MEASUREMENT AND CALCULATION, AND ELECTRONIC DEVICE AND MEDIUM

Document Type and Number:

WIPO Patent Application WO/2022/088240

Kind Code:

A1

Abstract:

Provided are an electric motor protection method and apparatus based on temperature measurement and calculation, and an electronic device and a medium. The method comprises: acquiring a vibration file, wherein the vibration file is a voltage signal that is adapted to a vibration event of an electric motor voice coil; calculating a predicted temperature of the electric motor voice coil according to the vibration file; and when the predicted temperature is higher than a pre-set temperature threshold value, performing correction processing on the vibration file.
