Motor with adjustable output, control method thereof, compressor and air conditioner

The invention discloses an adjustable output motor, a control method thereof, a compressor and an air conditioner. The adjustable output motor comprises coil windings arranged in the motor body, eachcoil winding is provided with a head end tap, a tail end tap and a plurality of intermediate taps to form a plurality of coil winding grades. All taps are connected with a controller, and the controller switches to the corresponding coil winding grades according to the running load. The invention designs a motor which can be adapted to high-efficiency operation under multi-load condition, and hasmultiple winding combinations, and can switch and use corresponding high-efficiency winding according to the system running load, so that the motor, the compressor and the air conditioner can keep high-efficiency operation at all times, and the energy efficiency of the system is improved. 本发明公开了种可调输出的电机、其控制方法、压缩机及空调器，其中可调输出的电机包括设置在电机本体内的线圈绕组，每个线圈绕组皆设有首、尾抽头和多个中间抽头，构成多种线圈绕组档次，所有抽头连接控制器，所述控制器根据运行负载切换至对应的线圈绕组档次；本发明设计了种可适应多负荷条件
