Description

Technical Field

[0001] The utility model relates to the field of motors, and in particular to a motor with a self-contained power generation device. Background Art

[0002] At present, in this type of synchronous start and synchronous operation permanent magnet motor, a driver or inverter is usually used to drive the motor. The motor is powered on by connecting the power bus to the driver, and then the driver is connected to the motor. According to modern safety production requirements, the driver or inverter is an electronic product that is prone to moisture or corrosion. The driver is generally required to be placed in the power distribution room. Therefore, the driver is generally far away from the motor, and affected by the data matching between the driver and the motor, the wires between the driver and the motor cannot be connected to other electrical appliances. For example, in order to cool a slow direct drive motor, due to the slow motor speed, the effect of installing a fan at the tail of the motor is not good, so an independent fan needs to be installed outside the motor. In order to power the fan, a wire can only be pulled from the power distribution room for the fan. Utility Model Content
