| 摘 要： | 从凸极率角度出发，对内部磁极结构电机提出了新的设计方法，为使电机的特性具有可比性，假设电机均运行于相同的基值点，并采取相同的控制策略，着重了研究凸极率（ld/lq)对电机最大可能速度，逆变器功能（VA）和电流控制特性的影响，所得结论对电机及其驱动系统的选择和有积极的参考指导作用。

| Abstract: | The new method was proposed to design linear synchronous motor with interior permanent under the flux-weakening speed control from the saliency ratio. In order to understand better the basic differences in the motor design, the same base and flux-weakening performance were fixed. The influence of the saliency ratio on inverter volt-ampere ratings, maximum feasible speed, and current control characteristics were discussed. The result is useful for the design motor and its controller. |
