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 .着重研究了凸极率 (ld/lq)对电机最大可能速度、逆变器功率 (VA)和电流控制特性的影响 .
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.
