Abstract

Aiming at the problem of excessive winding loss in high-speed permanent magnet energy storage electric machine when rectifier loads are taken into account, an 8-pole 48-slot high-speed permanent magnet energy storage electric machine was taken as the research object. A mathematical calculation model of winding loss was constructed, and researches on the number of winding layers, parallel branches and transposed winding technology were carried out. The results show that increasing the number of winding layers and parallel branches of the electric machine can reduce the proportion of eddy current loss in the total loss and decrease the winding loss. By comparing and analyzing the in-slot transposition mode and the end twist transposition method of the winding, the effectiveness of the end twist transposition method in suppressing the AC loss of the winding was verified. For the common operating conditions of the electric machine, the electric machine performance and efficiency of different schemes were compared. The simulation results show that the proposed optimization method can reduce the winding loss and improve the efficiency of the high-speed permanent magnet energy storage electric machine considering the rectifier load, and the accuracy of the simulation analysis has been verified by experiments.
