摘　　要：研究了盘式永磁微型发电机的磁路设计方法,完成磁路的模型建立、理论推导、仿真修正和实验验证,探讨磁路中主要结构参数对磁隙处磁场的影响规律以及参数间的约束关系。着重研究磁隙处磁感应强度的计算方法和微型发电机的结构参数优化方案,并归纳出盘式永磁微型发电机的磁路设计方法。理论计算与实验数据误差在7%以内,进而验证了磁感应强度计算方法的合理性和准确性。文中方法对此类电机的设计和优化具有指导意义。A design method of magnetic circuit in a disk-type permanent magnetic micro-generator is pro- posed, including modeling, theoretical analysis, simulation and experiment. The effects of the structural parameters on magnetic flux density in the magnetic gap and the constraint relations among the parameters are discussed. The calculation method of magnetic flux density in magnetic gap and the optimization scheme of structural parameters of micro-generator are studied. The design method of magnetic circuit in the planar permanent magnetic micro-generator is summarized. Errors between the theoretical calculations and experimental results are less than 7% , which verifies the rationality and accuracy of the calculation method of magnetic flux density.
