摘要

永磁同步电机以其独特的优点非常适合于混合动力汽车。然而，它们有两个主要缺点，即高成本和小速度范围。提出了一种永磁电机的优化设计方法。优化的目标是减少永磁体材料以保持恒转矩，并扩大转速和转矩范围。为此，推导了永磁同步电机的解析模型，并设计了相应的设计算法。然后利用遗传算法对部分机器规格进行优化。最后用有限元法对设计的机床进行了验证。

Optimal design of PMS machines for hybrid electric vehicles

Permanent magnet synchronous machines are well suited for hybrid electric vehicles due to their unique merits. However they have two major drawbacks i.e. high cost and small speed range. In this paper an optimal design of a permanent magnet machine is presented. A reduction of permanent magnet material for a constant torque and an extension in speed and torque ranges are chosen as the optimization aims. For this purpose the analytical model of the permanent magnet synchronous machine is derived and the appropriate design algorithm is devised. The genetic algorithm is then employed to optimize some machine specifications. Finally the finite element method is used to validate the designed machine.
