| 摘 要： | 高转速比异步变频电机电磁设计,既要满足高速弱磁区转矩不足,又要克服低速时磁路过饱和。以1 600 kW异步变频电机为例分析了等效电路参数变动特点,绘制了高低转速下转矩、效率、电压、电流和功率因数曲线；并得出了磁密、磁导率分布图,计算了不同工况下损耗的时间分布图。经电机型式试验测试,设计方案满足技术要求。

| Abstract: | The electromagnetic design of the high speed ratio asynchronous motor, that was, to meet the high speed weak magnetic area torque, but also to overcome the low speed when the magnetic passing through saturation. 1 600 kW asynchronous motor as an example, analysis of the equivalent circuit parameters change characteristics, the low speed torque, efficiency, voltage, current and power factor curve drawing, and the magnetic flux density, magnetic permeability distribution, distribution and temperature rise time loss under different conditions were calculated by the motor type test. The design met the technical requirements. |
