双馈电机数学模型及运行性能比对分析

从有刷双馈电机的原理出发,分析了级联式、鼠笼式和磁阻式无刷双馈电机的原理,从电机的结构、数学模型、运行性能角度指出了它们之间的内在联系。当不考虑级联式、鼠笼式无刷双馈电机的转子绕组电阻时,这些电机在不同坐标系下的磁链方程与电压方程结构形式完全相同。级联式、鼠笼式、磁阻式无刷双馈电机虽然实现了无刷,但存在其它的不足,耗材量增加,结构相对复杂,能量间接传递,不同旋转频率的磁场叠加。

Comparing Analysis of Mathematic Model and Operating Character of Different Doubly Machine

On the basis of the principle above brush doublu-fed and self-cascade brushless doubly-fed machines,analysed the principle of the squirrel-cage and reluctant brushless doubly-fed machines,and pointed out their internal relation above the structure,mathematical model and operating performance of machine.When the rotor winding resistance of the cascade set squirrel-cage brushless doubly-fed machine is ignored,these machines have the same structural style of flux linkage and voltage equations under the differe...
