摘要：

The rotor structure with the type of magnetic barrier is proposed for brushless doubly-fed machines (BDFMs) in recent years. Comparing with other types of reluctance rotor, it has strong magnetic field coupling ability. Temperature rise is the important indexes which influence electrical machine power density. In order to give full play to the potential of BDFM with magnetic barrier rotors, accurate and fast thermal calculation is very necessary. In this paper, the accurate model of rotor thermal road calculation was put forward for magnetic barrier rotor. By using the equivalent thermal network method, a temperature rise calculation program was written and different position temperature distribution was obtained. In the meantime, the steady-state temperature of BDFM was calculated by using the finite element method (FEM). At last, temperature calculation results obtained from two different methods were compared with experimental data from a 11 kW prototype and the correctness of the proposed rotor thermal road calculation model is verified. It has important significance to calculate temperature rise quickly for BDFM with similar rotor structure. © 2018 Chin. Soc. for Elec. Eng.
