Composite automotive low-voltage alternating current frequency modulation motor

Abstract

The invention discloses a composite automotive low-voltage alternating current frequency modulation motor, which comprises a motor base, a stator and a composite rotor, wherein the stator and the composite rotor are positioned in the motor base; the composite rotor is fixed on a main shaft of the motor; the stator adopts a tapped winding; and the composite rotor adopts a structure consisting of 35 percent of copper and 65 percent of silicon steel sheet. The motor has a compact space, and is maintenance-free and smaller than similar motors; production materials for the motor are saved; energy loss caused by an excitation device is avoided, and an energy saving effect is achieved; and the shortcoming of high failure rate of the excitation device is overcome, and the service life of the motor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a compound low-voltage AC frequency-regulated motor for vehicles. Background technique [0002] At present, most of the motors used in pure electric vehicles use DC motors as the driving motors, resulting in complex internal structures of the motors, many parts, high maintenance costs and low efficiency, so it cannot meet the requirements of low-voltage motors in the field of small size. , Maintenance-free high-efficiency requirements. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a compound low-voltage AC frequency modulation motor for vehicles with simple structure, small size and maintenance-free. [0004] The invention provides a compound low-voltage AC frequency modulation motor for vehicles, which includes a machine base, a stator located inside the machine ...
