Abstract

The invention relates to the technical field of motors, and discloses a brushless double-rotor motor structure for vehicles, which consists of inner and outer motors with radial magnetic circuit structures. The brushless double-rotor motor structure comprises an inner motor assembly consisting of an inner rotor (an inner rotor iron core unit and an inner rotor permanent magnet), a modulation rotorand an inner stator (an inner stator iron core unit and an inner stator winding), and an outer motor assembly consisting of an outer stator (an outer stator winding, an outer stator iron core unit and an outer stator permanent magnet) and an outer rotor. The modulation rotor is connected with an input rotating shaft and rotates along with the input rotating shaft, the inner rotor and the outer rotor are both rigidly connected with an output rotating shaft and rotate together with the output rotating shaft, and the inner stator and the outer stator are separated through stator magnetism isolation and fixed to a motor shell. Compared with the prior art, the brushless double-rotor motor structure can be applied to the field of hybrid electric vehicles, a brushless double-rotor motor can be realized, the work is reliable, and the power requirements of different working conditions are met through the control of the inner motor and the outer motor.

Description

technical field [0001] The invention belongs to the field of motor design, in particular to a brushless double-rotor motor structure applied to hybrid vehicles. Background technique [0002] With the development of hybrid electric vehicles (Hybrid Electric Vehicle, HEV), the electromagnetic transmission hybrid system using dual-rotor drive motors has been proposed and attracted attention. Compared with traditional vehicle drive systems, the electromagnetic transmission hybrid system can achieve high efficiency. The continuously variable transmission power coupling has high fuel economy; compared with the mechanical transmission hybrid system using planetary gears, the electromagnetic transmission hybrid system has a compact structure, and the dual-rotor drive motor can replace the starter / generator, electric motor Realize the coupling and distribution of hybrid power, so this system has become one of the development directions of hybrid power system. [0003] The dual-rotor...
