Abstract: Each of the motor stator poles has a window cut out which functions to create an unbalanced flux distribution and move the magnetic neutral off the centerline of the stator pole. A plurality of permanent magnet rotors are mounted on a common shaft to permit a desired rotor to be moved into the stator field. Each rotor has a different number of poles selected so with any rotor there will always be a whole odd number of poles within the span of a stator pole. Speed is determined by the number of poles in the rotor in operative position.
Abstract translation: 每个电动机定子极都有一个窗口，其功能是产生不平衡的磁通分布，并使磁性中性线离开定子极的中心线。 多个永磁转子安装在公共轴上以允许期望的转子移动到定子磁场中。 每个转子具有不同的极数，因此任何转子在定子极的跨度内总是有一个整数个极数。 速度由转子在工作位置的极数决定。

Abstract: An electric motor where the stator is positioned between motor end caps. The stator comprises a pair of housings that contain coil windings and one of the housings has a plurality of axially extending tabs bent over the other housing to secure the housings from axial separation. The bent over portion of a tab is compressed against a wall of an end cap when the stator is assembled between the end caps of the motor and is bendable to accommodate variations in axial dimensions of the motor. One of the motor housings has additional axially extending tabs that are received within openings formed in an end wall of the motor housing to prevent radial displacement of the stator relative to the motor housing.

Abstract: A small two-phase motor having first and second field coils which each cooperate with a long, thin cylindrical rotor. The rotor is provided with only a single pair of nonsalient rotor poles and has a length to diameter ratio which advantageously is at least about 2.5. A stator pole piece assembly is in magnetic flux relationship with the rotor and includes first and second sets of salient stator poles which respectively cooperate with the first and second field coils. There are only two salient stator poles in each set, and the stator poles are angularly spaced apart by approximately ninety electrical degrees. In some embodiments one of the stator poles in the first set and one of the stator poles in the second set extend in opposite directions parallel to the rotor axis from a single tubular member which forms a part of the pole piece assembly.

Abstract: An electric motor with microprogrammed controller and dual-functioning brushless commutation/rectification circuitry contained entirely within a wheel. The principal use of this electric motor is intended to be, but not limited to, powering a four-wheel drive electric vehicle through normal driving modes and serving as a power-recovery generator during braking. The magnetic and electronic configuration is optimized within the wheel to provide high torque and efficiency without the use of gear reductions, chain or belt drives, transmission, rotating axles, differentials, universal joints, or brushes. Power losses from mechanical drive system couplings are thus eliminated. Except for the wheel and bearings, there are no moving parts. Also, the wheel is virtually free of devices that are subject to mechanical failure.

The rotor is supported for rotation within the stator about the axis of the motor and with an annular air gap between the stator and the cup-form rotor, and means including a stator coil is adapted to be energized to rotate the rotor relative to the stator. An output shaft coaxial with the rotor extends outwardly from one end of the stator, and a stationary support bushing for the output shaft extends into the internal volume defined by the rotor. A gear train is mounted in the space between the inward end of the support bushing and the closed end of the cup-form rotor, and is coupled between the rotor and the output shaft to provide a predetermined speed reduction ratio between the rotor and the output shaft. The gear train comprises at least three gear members, a first gear member cantilever mounted from the stationary support bushing, a second gear member cantilever mounted from the closed end of the cup-form rotor, and a third gear member mounted from said output shaft, one of the gear members comprising a cluster of two gears mounted in offset relation to the output shaft and the other two gear members being coaxial with the output shaft.

Abstract: A synchronous motor of improved construction characterized by a large diameter rotor mounted in axially juxtaposed parallel relation to the stator coil or coils, rather than within the interior of the stator coil or coils; the stator coil or coils being of substantially the same diameter as the rotor and having stator pole pieces circumscribing the rotor at the outer periphery of the coil or coils, rather than the inner periphery of the coils.In the preferred construction, first and second annular electrical coils of given outer diameter are positioned on opposite sides of a coaxially mounted wheel-like rotor of substantially equal outer diameter. A pair of circular plates of magnetically permeable material are positioned adjacent opposite sides of each coil perpendicular to the axis thereof, and have tooth-like flanges extending axially from their outer edges adjacent the outer periphery of the rotor, whereat the ends of the flanges of each pair of plates define a plurality of interleaved poles. The periphery of the rotor is of permanent magnet material having alternating north and south poles formed circumferentially therearound. Upon the application of an a.c. voltage across the coils, adjacent poles formed by the flanges of each pair of plates become of opposite magnetic polarity, and alternate polarity with each half cycle of the a.c. voltage, to turn the rotor.Maximum torque may thus be produced within given dimensional tolerances due to maximization of the effective moment arm of the rotor and maximization of the number of windings accommodated by the coils.
