本发明公开了四相32/24极结构开关磁阻电机极性分布方法及其应用，包括A、B、C和D四相，A相包含A1、A2、A3、A4、A5、A6、A7和A8，采用NSNSNSNS极性分布，B相包含B1、B2、B3、B4、B5、B6、B7和B8，采用SNSNSNSN极性分布，C相包含C1、C2、C3、C4、C5、C6、C7和C8，采用SNSNSNSN极性分布，D相包含D1、D2、D3、D4、D5、D6、D7和D8，采用NSNSNSNS极性分布。本发明能够满足节能调速风机和水泵不同运行工况，实现电机动态转矩闭环控制，减小转矩脉动，提高转矩精度，使得电机在不同运行工况能够平滑切换，提高电机运行效率。
摘要（英）：

The present invention discloses a polarity distribution method for four-phase 32/24 structure switched reluctance motor and application thereof, comprising four phases of A, B, C and D, wherein phase A includes A1, A2, A3, A4, A5, A6, A7 And A8 using the NSNSNSNS polarity distribution, phase B includes B1, B2, B3, B4, B5, B6, B7 and B8 using the SNSNSNSN polarity distribution, phase C includes C1, C2, C3, C4, C5, C6, C7 And C8 using the SNSNSNSN polarity distribution and phase D includes D1, D2, D3, D4, D5, D6, D7 and D8 using the NSNSNSNS polarity distribution. The invention can meet the different working conditions of an energy-saving speed-regulating fan and a water pump, realizes the closed loop control of the motor's dynamic torque, reduces the torque ripple and improves the torque precision, so that the motor can be switched smoothly under different operating conditions and that the motor operating efficiency is improved.
