Abstract

The invention provides a double-winding six-phase motor and an electric automobile adopting the double-winding six-phase motor. The base of the double-winding six-phase motor is provided with a firststator and rotor system, wherein the first stator and rotor system comprises a first stator, a first rotor and a first three-phase winding; a second stator and rotor system which comprises a second stator, a second rotor and a second three-phase winding; and a rotating shaft, wherein the first stator and rotor system and the second stator and rotor system are installed on the rotating shaft in theaxial direction of the rotating shaft and share the rotating shaft to provide power output.

Description

technical field [0001] The invention relates to the field of electric vehicle transmission systems, and more specifically, to a double-winding six-phase motor and an electric vehicle using the double-winding six-phase motor. Background technique [0002] With the development of new energy vehicles, battery technology is becoming more and more mature and charging devices are becoming more and more perfect, and pure electric vehicles also have the characteristics of low air pollution, low noise and high comfort, so the use of pure electric vehicles is increasing year by year . [0003] At present, the transmission system of electric vehicles mainly includes two transmission modes: motor direct drive and motor-gearbox system. The structure of the motor direct drive system is simple and reliable, and the technology is mature. However, due to the limitation of the characteristics of the motor itself, it is difficult to economically take into account the requirements of high spee...
