ELECTRIC MOTOR, ELECTRIC MOTOR CONTROL SYSTEM, ELECTRIC MOTOR TEMPERATURE MEASURING METHOD AND UNMANNED AERIAL VEHICLE

WIPO Patent Application WO/2019/084721

A1

Disclosed is an electric motor, comprising a rotor (10) and a stator (20), wherein the rotor (10) comprises a rotor core (11) and a magnetic element (12) disposed on the rotor core (11). The stator (20) comprises a stator core (21) and a stator winding (22) disposed on the stator core (21). An additional winding (23) is further provided inside the electric motor, the additional winding (23) is wound around the stator core (21), and a change in electrical parameters of the additional winding (23) indicates an abnormal temperature of the electric motor. Since the additional winding is wound around the stator core, when the temperature changes anywhere inside the electric motor, same can be monitored by the additional winding, so that global temperature monitoring of the interior of the electric motor can be realized while the monitoring interface pressure and equipment costs can be reduced. In addition, further disclosed are an electric motor control system and an unmanned aerial vehicle using the electric motor, and an electric motor temperature measuring method applied to the electric motor.
