摘要： A variable reluctance drive system including a motor and corresponding converter for improved current commutation. The motor incorporates a salient pole rotor (16) and a salient pole stator (10) having one or more full pitch windings (20) which operate by mutual inductance to transfer the current from the active short pitch winding following phase alignment (each short pitch winding comprising two short pitch coils A1-2, B1-2 or C1-2). This increases output torque and/or speed and permits a number of simple and economical converter circuits (Figs. 7-11).

摘要： A device for field weakening in a doubly-salient variable reluctance motor having permanent magnets (22, 24) in the stator (10). The field weakening increases the constant power range of the motor and is accomplished by controlled movement of steel insets (16, 36) toward and away from the sides of the stator (10) proximate the permanent magnets (22, 24) to provide a controllable by-pass flux path thereabout. Alternatively, the field weakening may be accomplished by a flux by-pass collar (40) which may be angularly positioned around the stator (10) to bridge the permanent magnets (22, 24) of the motor with discrete magnetic sections, thereby providing an alternate by-pass flux path around the permanent magnets (22, 24) in addition to the main air gap flux path. A third alternative means for maintaining a constant power range is accomplished by controlled axial sliding of the permanent magnets (22, 24) themselves into and out from the stator (10).
摘要翻译：一种用于在定子（10）中具有永磁体（22,24）的双重可变磁阻电动机中的弱磁化装置。磁场弱化增加了电动机的恒定功率范围，并且通过使钢插入件（16,36）朝向和远离定子（10）的侧面靠近永磁体（22,24）的受控移动来实现，以提供可控制的旁路磁通路径。或者，弱磁化可以通过可以围绕定子（10）成角度地定位以使离散的磁性部分与马达的永磁体（22,24）桥接的助焊剂旁通轴环（40）来实现，从而提供除了主气隙磁通路径之外，永久磁铁（22,24）周围的交替的旁路磁通路径。用于保持恒定功率范围的第三替代方案是通过永磁体（22,24）本身进入和离开定子（10）的受控轴向滑动来实现的。

摘要： An economical reluctance drive/generator system including a double AC-fed reluctance motor (2) having two three-phase stator windings (p1 and p2) and a rotor (20) with simple salient poles. The speed of the motor (2) may be varied by alternating the frequency of the excitation voltage applied to one set of the stator windings while keeping the frequency of the excitation voltage applied to the other set of windings constant. The system also includes a frequency converter (30) for altering the frequency of the excitation voltage applied to one set of the stator windings. The system is accomplished with a set of structural constraints, and these insure the proper electromagnetic coupling between the two sets of stator windings and therefore insure the torque production and economical energy conversion in the system. The VA rating of the frequency converter (30) for this system can be reduced if the speed range is small and the rotor copper loss is eliminated in this motor or generator (2).
摘要翻译：一种经济的磁阻驱动/发电机系统，包括具有两个三相定子绕组（p1和p2）的双交流馈电电动机（2）和具有简单凸极的转子（20）。可以通过交替施加到一组定子绕组的激励电压的频率同时保持施加到另一组绕组的激励电压的频率恒定来改变电动机（2）的速度。该系统还包括用于改变施加到一组定子绕组的激励电压的频率的变频器（30）。该系统通过一系列结构约束来实现，这些确保了两组定子绕组之间的适当电磁耦合，从而确保了系统中的扭矩产生和经济的能量转换。如果该电机或发电机（2）中的速度范围很小并且转子铜损耗被消除，则该系统的变频器（30）的VA额定值可以降低。

摘要： A new class of doubly-salient machines which incorporates a specific stator/rotor pole arrangement to provide a linearly increasing flux linkage over the entire area of pole overlap, and either stationary permanent magnets (22, 24) mounted in the stator (10), or one or more auxiliary field windings coiled about the stator, or a combination of stationary permanent magnets and auxiliary field windings. In each of the three cases, the permanent magnets or auxiliary winding(s) generate the primary flux and block and thereby limit flux in the ordinary path of the secondary flux (due to the stator windings) through the stator. The altered magnetic structure utilizing four stator (12) and six rotor poles (18) increases efficiency when operated as a generator, and provides greater output torque when operated as a motor.
