Title:
THREE-PHASE MOTOR AND TEMPERATURE DETECTION METHOD AND DEVICE, AND GIMBLE AND MOVABLE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2020/056630
Kind Code:
A1
Abstract:
A three-phase motor and a temperature detection method and device, and a gimble and a movable platform. The method comprises: obtaining a first temperature between a first-phase coil and a second-phase coil, and obtaining the heating work of one coil of coils of each phase; and determining a second temperature of the coils of each phase according to the first temperature and the heating work of one coil of the coils of each phase. The present invention can determine the temperature of the coils of each phase by obtaining the temperature between coils of two phases and the heating work of one coil of the coils of each phase, so that data support is provided for the temperature protection of the three-phase motor, and the implementation method is simple.
