Brushless rotor permanent magnet dual-mechanical-port motor structure for vehicle

Abstract

The invention relates to the technical field of motors, and discloses a brushless rotor permanent magnet dual-mechanical-port motor structure for a vehicle. The motor structure comprises an inner rotor, a modulation rotor, an inner stator, an outer stator and an outer rotor; the modulation rotor rotates with an input rotating shaft; the inner rotor and the outer rotor are rotatably connected withan output rotating shaft, and the inner stator and the outer stator are separated by the stator; an inner rotor permanent magnet is arranged on the inner rotor and comprises 2n mixed permanent magnetpoles which are uniformly distributed along the circumference; each mixed permanent magnet pole adopts inner rotor rare earth permanent magnets and inner rotor ferrite permanent magnets which are arranged in parallel at intervals; and the outer rotor is formed by uniformly placing 2n1 outer rotor groove iron core units with large bottoms and small notches and 2n1 outer rotor permanent magnets at intervals along the circumference. The motor structure is applied to the field of hybrid electric vehicles, can realize brushless and high torque density of a dual-mechanical-port motor, is reliable inwork, and meets the power requirements of different working conditions 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 mechanical port motor applied to hybrid vehicles. Background technique [0002] With the development of HEV (Hybrid Electric Vehicle, HEV), the electromagnetic transmission hybrid power system using dual mechanical port drive motors has been proposed and received attention. Compared with the traditional vehicle drive system, the electromagnetic transmission hybrid power system can achieve high Efficient continuously variable transmission power coupling with 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 mechanical port drive motor can replace the starter / generator 1.
