摘　　要：起动阻力矩是永磁风力发电机设计时的一个重要指标,它直接影响着发电机的起动和低速性能。本文从起动阻力矩产生的原因出发,运用铁磁学的基本原理,推导出低速永磁风力发电机起动阻力矩的具体计算公式。通过和发电机的实测结果比较,其偏差较小,在进行该类发电机的设计时,具有很好的参考价值。Starting Resistant Moment (SRM) is an important index for designing of the permanent magnet wind power generator. It effects the starting and low-speed performances of the generator directly. Based on the theory of ferromagnetism, a formula for cmputing the SRM of low-speed permanent magnet wind power generator was deduced in this paper. It is shown that the error between the measured value and the computed value is little. It is valuable to deduce the formula in designing this kind of generator.
