Abstract

An motor comprising a rotor (10) and a stator (20), the rotor (10) comprising a rotor core (11) and a magnetic element (12) disposed on the rotor core (11), the stator (20) comprising a stator core (21) and a stator winding (22) disposed on the stator core (21), the motor is further provided with an additional winding (23), and the additional winding (23) is wound On the stator core (21), a changein electrical parameters of the additional winding (23) indicates an abnormal temperature of the motor. Since the additional winding is wound around the stator core, when the temperature change occurs anywhere in the motor, the additional winding can be monitored, thereby realizing global temperature monitoring of the motor interior and reducing the monitoring interface pressure. And equipment costs. In addition, it relates to a motor control system and an unmanned aerial vehicle using the motor, and a motor temperature measuring method applied to the motor.

Description

technical field [0001] The embodiments of the present invention belong to the field of motors, and in particular relate to a motor, a motor control system using the motor, an unmanned aerial vehicle, and a motor temperature measurement method applied to the motor. Background technique [0002] Motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. In a broad sense, it includes motors, generators and transformers. It can be divided into various motors such as permanent magnet motors and induction motors according to their structures. [0003] The motor is an instrument for converting electrical and mechanical energy. According to the entropy increase principle of the second law of thermodynamics, there is no energy conversion process with a conversion efficiency of 100%. Therefore, the motor will generate energy loss when it is working, and the lost energy will be converted in...
