Calculation of Stator End Leakage Inductances for Multiphase Induction Machines Based on Magnetic Vector Potential
摘要
Abstract
A novel numerical method based on the magnetic vector potential is proposed to calculate stator end leakage inductances of the multiphase induction machine with the conic angle of end-windings taken into consideration. To acquire the leakage inductances between end-windings, the flux is obtained by a line integral of vector-potential along the end-winding sides, which is different from the traditional surface integral of flux density. Therefore, the magnetic vector potential method is of more accuracy as well as higher computation speed, and makes it easy to deal with the complicated end-winding frameworks. By following the general procedure which combines the coil end leakage inductances with the incidence matrix to obtain the phase end leakage inductances, the new method retains advantages of flexibility and versatility. The calculation is illustrated by a 15-phase induction machine and the validity of the magnetic vector potential method is showed in the results.关键词
