摘　　要：永磁同步发电机越来越多地应用于风力发电。永磁体的矫顽力有限,必须防止永磁体的不可逆去磁。本文应用ANSYS软件,计算了永磁体在环境温度为 60℃时,电机突发短路条件下,最恶劣的去磁位置时的磁场分布,对实际的运行情况进行了计算分析。The Permanent magnet synchronous generators are widely being used in electricity generating by wind power. Because of limited coercive force of permanent magnet, the non-reversible demagnetization of it must be prevented. In this paper, the magnetic field distribution of the permanent magnet at the ambient temperature 60℃ at the most serious position of demagnetization is calculated under the condition of sudden short circuit of generator, and the actual operation conditions are calculated and analyzed by the soft ware ANSYS.
