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： Described are homopolar bearingless slice motors which include an array arrangement of permanent magnets on stator teeth, and a magnet-free rotor having a unique surface geometry. Also described are related components of such motors. The permanent magnet arrays provide homopolar bias flux to the rotor, and salient features on the rotor surface route the bias flux toward paths desirable for force and torque generation. In an illustrative embodiment, two magnet arrays are placed at the tips of stator teeth, so as to provide the bias flux via relatively short flux paths. By modulating current through windings based upon the rotor radial and angular position measurements, the stator can levitate and rotate the rotor.

摘要： A first member has a magnet assembly that includes at least one permanent magnet pair, and a second member includes an electromagnetic coil. A control circuit controls the supply of power to the electromagnetic coil as well as regeneration of power from the electromagnetic coil. The permanent magnet pair generates its strongest magnetic field along a magnetic field direction on homopolar contact planes where first magnetic poles contact one another, outward from the center of the permanent magnet pair along the magnetic field direction. The electromagnetic coil is positioned such that current will flow in a direction intersecting the magnetic field direction.
