Document Type and Number:
WIPO Patent Application WO/2022/193556
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present disclosure are a motor phase loss detection method and device, and a storage medium. The motor phase loss detection method comprises: performing analysis on a given torque, torque feedback, and phase current feedback, determining a phase loss state of a motor on the basis of the analysis result, and outputting corresponding information; when the given torque satisfies a determination condition, if the torque feedback is in a zero torque feedback state, determining that a motor power line is not connected; and when a torque is in a non-following state, if a certain phase current in three phases i.e., UVW is in a zero current state, determining that the phase is lost.
