摘要： A stator or rotor of an electric motor or generator comprises a core formed of ferromagnetic material having a plurality of teeth arranged circumferentially about an axis. In one aspect of the invention, at least one retaining member connects the end portions of at least two of the teeth to each other in a manner inhibiting relative movement between said tooth end portions. By inhibiting relative movement between said tooth end portions, vibration is reduced. Vibration can also be reduced by welding interior surfaces of a core to each other. Reducing the vibration reduces the noise emissions of the rotor or stator during operation.

摘要： A multiple phase switched reluctance motor (30). A stator assembly (32) has a plurality of inwardly salient teeth (34a-34l) terminating at a central bore (36) and at least one redundant pole set for each motor phase. A rotor assembly (38) disposed for rotation in the bore has a plurality of rotor teeth (42a-42d). The number of rotor teeth is proportional to the number of stator teeth. The pole redundancy helps distribute ovalizing forces on the motor assembly. This lessens the effect of these forces and reduces motor noise produced by the assembly in response to the forces. The stator may have multiple teeth per pole and the rotor a multiple of the determined rotor teeth. The number of rotor teeth exceeds the number of stator teeth so the rotor teeth overlap the stator teeth. This improves starting torque in a desired direction of motor rotation. The ratio between stator poles and rotor poles includes the following for single tooth per pole motor constructions 6(n):2(n); 6(n):4(n); 6(n):8(n); 8(n):6(n); 8(n):10(n); where n is a positive whole integer having a value of 1 or 2 for some motor applications, and a higher value for certain ratios for other applications. In addition, in some motor constructions, the rotor teeth are formed to provide dual air gaps between the stator and rotor assemblies.
摘要翻译：多相开关磁阻电动机（30）。定子组件（32）具有终止于中心孔（36）的多个向内突出的齿（34a-34l）和至少一个用于每个电动机相的冗余极组。设置用于在孔中旋转的转子组件（38）具有多个转子齿（42a-42d）。转子齿数与定子齿数成正比。极点冗余有助于在电机组件上分配椭圆形力。这减轻了这些力的影响并且减小了由于组件响应于力而产生的电动机噪音。定子可以具有每极多个齿，并且转子具有确定的转子齿的倍数。转子齿数超过定子齿数，因此转子齿与定子齿重叠。这提高了电动机旋转的期望方向上的起动转矩。定子极和转子极之间的比例包括以下单电机每极电机结构6（n）：2（n）; 6（n）：4（n）; 6（n）：8（n）; 8（n）：6（n）; 8（n）：10（n）; 其中n是对于一些电动机应用具有值为1或2的正整数整数，并且对于其它应用而言具有较高的某些比率值。此外，在一些电动机结构中，转子齿形成为在定子和转子组件之间提供双气隙。

摘要： A hybrid single-phase variable reluctance motor includes a stator with four inwardly salient teeth evenly spaced around a central core. A phase winding is operatively associated with two diametrically opposed stator teeth. Energization of the phase winding causes a temporary magnetization of those two teeth. A rotor disposed for rotation in the central bore has two outwardly salient teeth disposed generally at 180 degrees with respect to each other. A single permanent magnet is disposed adjacent the central bore at the end of one of the stator teeth other than the two having phase windings. A position sensor is disposed at the fourth stator tooth for detecting the rotational position of the rotor in the central bore. The position sensor is disposed in one quadrant of the motor in which the flux resulting from the permanent magnet and the flux resulting from the energization of the phase winding are in the same direction.

摘要： A switched reluctance motor has its stator poles divided into at least three phases, each phase having its own independently switchable phase windings wound around the corresponding stator poles. First switch elements control application of power to the windings of the first phase, second switch elements control application of power to the windings of the second phase, and third switch elements control application of power to the windings of the thirds phase. For low speed operation of the motor, the switch elements for each phase are controlled to apply power to its respective phase windings from a selected turn-on angle to a selected turn-off angle. The maximum difference in low speed operation between the turn-on angle and the turn-off angle for each phase is no greater than the angle subtended by adjacent stator poles as measured from the geometric center of the stator. For high speed operation, only the windings of the first phase are energized, and the difference between the turn-on angle and the turn-off angle for the first phase windings is greater than the angle subtended by adjacent stator poles.
