Abstract:
?An interior permanent magnet synchronous machine ( IPMSM) with double-layer permanent magnets (PMs) used in electric vehicles (EVs) is proposed,of which the basic electromagnetic relationship are analyzed,and an optimization analysis is conducted. The motor structure model was established by using finite element analysis software,the air-gap flux density and harmonic distortion rate changing rule were analyzed when unilateral air-gap is at different lengths. The variation tendency of cogging torque was investigated by the method of optimizing slot-opening width of the stator. The output torque and torque ripple are obtained by changing Rib ( the second layer on both sides of the PM separation bridge spacing interval) and O2 ( the first layer of PM bridge between the shaft). The efficiency was analyzed when changing the size of the double-layer PM,and the optimal size of PM parameters was obtained. The corresponding experimental results show that the measured and simulation values basically match,which verifies the rationality of the designed prototype machine
