摘要
文章从组合转子电机的相量图出发,建立了数学模型,在变频器供电开环V/f控制模式下,用4阶龙格-库塔法分别计算了轴向叠片段(ALA)和永磁段(SPM)参数对组合转子电机的转速、转矩和牵入同步的影响。计算结果表明组合转子电机的起动性能介于ALA和SPM转子电机之间,选择合适特征参数k、α值及电机的主要参数L_d和L_q,可优化组合转子电机的动稳态性能。
A mathematical model on hybrid rotor motor was established according to its phasor diagram, with an open loop power inverterV/fcontrol mode, an axially- laminated anisotropic （ALA） part and a surface permanent magnet （SPM） part were calculated to analyze their impacts on the rotational speed, the torque and pulling into synchronization on the hybrid rotor motor by employing 4 - order Runge - Kutta. The results show that the performance of hybrid rotor motor was between the ALA and the SPM rotor motor, a suitable k, a and the main parameters Ld and Lq can optimize the performance of dynamic and steady - state of the hybrid rotor motor.
