Abstract: The laminations respectively comprising the rotor and stator poles of a switched reluctance machine (SRM) are skewed as they are stacked during machine assembly in order to reduce the tendency of the SRM to flatten and thereby assume an oval shape during machine operation. As a result, the acoustic noise generated by the SRM during machine operation is substantially reduced.

Abstract: The invention is directed to an electric motor construction having a magnetic flux return path which exhibits very low losses due to eddy currents or hysteresis, and simplifies construction thereof. In the motor construction, the magnetic flux return path is constructed from discrete magnetic material wire which is wrapped or otherwise formed in the desired return path configuration. The magnetic material wire is wound in a direction which generally crosses the flow of magnetic flux and yet is substantially tolerant of cross-winding fields. In this way, the flux return path provides easy construction in that coil winding techniques may be used, and the winding direction is less critical as it can cross the flow of flux therein. The flux return path greatly reduces eddy current losses as the cross section of the path to eddy current flow is the cross section of discrete wires, and because the discrete wires are formed with high packing fraction which will minimize skin effects especially at high frequencies.

Abstract translation: 本发明涉及具有磁通返回路径的电动机结构，其由于涡流或滞后而显示出非常低的损耗，并且简化了其结构。 在电动机结构中，磁通返回路径由分离的磁性材料线构成，其被包裹或以其它方式形成为期望的返回路径构造。 磁性材料线沿着通常穿过磁通量的方向缠绕，并且基本上容忍交叉绕组磁场。 以这种方式，磁通返回路径提供了易于构造，因为可以使用线圈绕组技术，并且绕组方向不太重要，因为其可以穿过其中的焊剂流。 磁通返回路径大大降低了涡流损耗的路径，因为涡流流动的横截面是离散导线的横截面，并且因为离散导线形成有高填充分数，这将使皮肤效应特别是在高频下最小化。

Abstract: Motor for commercial and industrial applications such as golf carts and lift trucks. Features include a thin shell; stator; stator winding; and rotor. Rotor laminations have equally circumferentially spaced semi-closed slots having area for receiving conductors, and the ratio of the number of rotor lamination slots to the rotor outer diameter (measured in inches) is greater than 14.0. In one construction, this ratio is about 15.75; the ratio of the outer diameter to the rotor slot length is from about 9.04 to about 9.16; and the ratio of rotor slot depth or length to rotor slot opening width is from about 10.8 to about 12.5. Cylindrical stator lamination has a given outer diameter and a certain bore diameter determined by the distance between opposing poles. Through-bolt holes are located in the yoke, proximate the outer periphery thereof, and centered with respect to each pole. The ratio of stator pole neck minimum width to two times the yoke thickness or width is from about 0.809 to about 1.009. Methods of assembling motor components are also revealed.

Abstract: An arrangement for mounting a stator assembly (12) of a dynamoelectric machine (10) in a housing (16) employs a plurality of circumferentially distributed mounting supports (56) on the interior of the housing (16) cooperating with pairs of axially aligned radial extensions (54) of the stator assembly (12). Opposed, axially inner faces (62) of paired radial extensions (54) sandwich axially outer end faces (60) of an associated mounting support (56). Threaded fasteners (52) secure the radial extensions (54) to the end faces (60) of the mounting supports (56). Oversized mounting holes (58) in the radial extensions (54) and shims (74) can be used to allow for lateral and axial adjustment, respectively, of the mounted stator assembly (12).

Abstract: A rotor for an electric motor energized by permanent magnet means comprises positioning devices for permanent magnets. These positioning devices consist of positioning rings disposed in the region of each end face of a rotor body and at least one inner positioning ring disposed on the rotor body between the two. The positioning rings comprise positioning webs which extend only over a small part of the length of the outer peripheral surface of the rotor body and which partially define compartments for in each case a permanent magnet. On the one hand, this ensures accurate and simple mounting of the permanent magnet while at the same time it reduces the moment of inertia of the rotor.
