摘要
The stator slot of low-speed high-torque permanent magnet synchronous motor (LHPMSM) is generally designed as straight slot, due to the need of wire embedding process, which will introduce a large number of tooth harmonics. At the same time. Tooth harmonics worsen the eddy current loss of permanent magnets(PMs), leading to continuous temperature rise, demagnetization of PMs, and affecting the working performance of motor. In this paper, a slot wedge made of composite material is proposed and a magnetic insulation slot is introduced into the rotor. The optimized model not only decreases the eddy current loss, but also improves the electromagnetic performance of LHPMSM.
