PM material analysis of permanent magnet synchronous generator in wind turbines
Permanent magnets (PMs) material analysis of permanent magnet synchronous generator (PMSG) in wind turbine is studied in this paper. The direct driven PMSG (DDPMSG) system has high potential for the large scale wind turbines because of its robustness, increased energy yield and reliability compared to others. However, the main advantage of DDPMSG is the high cost of PMs and the demagnetization risk at high temperature. Therefore, the comparative analysis in terms of PM type chosen for 1.5 MW PMSG is presented in this paper. The comparison is made taking into discussion about the electromagnetic criteria for four types of PMs: AlNiCo, XG 196/96 and two rare earth PMs — SmCo and NdFeB. Maxwell 2D RMxprt is used for analyzing of the cogging torque and airgap flux density at different PM materials used in PMSG for wind energy generation. According to simulation results, NdFeB is the most suitable magnet for low speed PMSGs.
