摘要

复合结构永磁同步电机(CS-PMSM)是近年来发展起来的一种新型电机，由两台电机组成。在混合动力汽车(HEV)上具有广阔的应用前景。这台机器的主要缺点之一是，由于其中一个转子有电枢绕组，必须使用电刷和滑环。为了解决这一问题，本文做了一些研究工作，并提出了一种新的无刷方案。新型无刷永磁同步电机由一个定子电机(SM)和一个无刷双转子电机(BDRM)组成。由于BDRM采用了新的爪极结构，绘制了等效磁路，建立了模型并采用三维有限元法对其进行了优化，优化结果表明，反电动势和转矩均满足要求。

Design of a brushless compound-structure permanent-magnet synchronous machine for HEV propulsion system

Compound-structure permanent-magnet synchronous machine (CS-PMSM), which is composed by two electric machines, is a new type of machine developed these years. It has a wide application prospect on hybrid electric vehicle (HEV). One of the main disadvantages of this machine is that as one of the rotors has armature winding in it, a brush and slip rings must be used. Some research work has been done to solve this problem and a novel brushless scheme is proposed in this paper. The new type of brushless CS-PMSM consists of one stator machine (SM) and one brushless double rotor machine (BDRM). As the BDRM has a new claw-pole structure, the equivalent magnetic circuit is drawn, then the model is built and optimized by using 3D finite-element method (FEM), the results of the optimization show both the back electromotive forces (BEMFs) and torque meet the requirements.
