摘要
通过理论分析和有限元仿真,对定子绕组采用△联接的自起动永磁同步电动机的气隙磁场、转子阻尼绕组的电流、转矩、转速、损耗等进行分析,可以得出定子绕组采用△联接时,不仅会大大增加稳态运行时的转子铜耗,还会引起转矩、转速的波动。因此,定子绕组应慎用△联接。将△联接与Y联接的电机做了对比分析。
Through theoretical analysis and finite element simulation,the air gap magnetic field,rotor damper winding current,torque,speed and power losses were analyzed for the line-start REPMSM in steady-state operation.The results showed that when the stator windings are △ connected,not only the rotor damper winding current would greatly increase,but also cause torque,speed fluctuations.So compared with Y connected windings type,the △ type should be carefully used.
