    • A regenerative switched reluctance motor and a motor drive system therefor are provided. The motor has a rotor 33 with stacked rotor units 33a-33d each comprising 2n salient poles and a stator 31 with stacked stator units 31a-31d surrounded by and corresponding to the rotor units and each comprising 4n magnetic poles to form a predetermined gap with the salient poles of the corresponding rotor unit. A first excitation coil 32(A) is wound on every other one of the 4n magnetic poles of each stator unit, while a second excitation coil 32(B) is wound on the remaining magnetic poles thereof. The rotor units are sequentially shifted by a predetermined angle in angular position relative to the stator units. The switched reluctance motor and the motor drive system can efficiently drive the motor and recover regenerative power with little torque ripple and noise.
    • 提供一种再生式开关磁阻电动机及其电动机驱动系统。 电动机具有转子33,转子33具有堆叠的转子单元33a-33d,每个转子单元包括2n个凸极,定子31具有层叠的定子单元31a-31d,该转子单元由转子单元包围并对应于转子单元,每个包括4n个磁极,以形成与 相应转子单元的极点。 第一励磁线圈32(A)缠绕在每个定子单元的4n个磁极中的每一个上,而第二激励线圈32(B)缠绕在其剩余的磁极上。 转子单元相对于定子单元在角度位置顺序地偏移预定的角度。 开关磁阻电动机和电机驱动系统可以有效地驱动电机,并以较小的转矩脉动和噪声来恢复再生电力。
