永磁同步电机定子匝间短路故障阻抗参数分析
Impedence Parameters Analysis of Permanent Magnet Synchronous Motor under Inter-Turn Short Circuit Fault
摘要
Abstract
Permanent magnet synchronous motor's (PMSM's) equivalent circuit under the normal and inter-turn short circuit fault state was analyzed,the finite element analysis model was established,the inductance of the normal and fault turn under the fault was presented,and the relations of winding inductance,circuit,torque and the short turns number was analyzed.The results showed that the vibration of the torque was increased while the average was essentially invariant;The currents of each phases were increased and the phase where the inter-turn short circuit fault occurs increased more than the other normal phases,the short circuit current decreased with increasing fault turns;The inductance of normal phase was essentially invariant while the inductance of fault phase and short circuit turns relate the number of fault turn.关键词
