摘要： An electronically commutated motor has substantially constant air gap energy to reduce cogging. A rotatable assembly has permanent magnet elements which rotate about an axis of rotation. The elements are oriented with respect to said axis of rotation to provide a magnetic field with lines of flux along a plane forming a skew angle of s.sub.1 mechanical degrees with respect to the axis of rotation, wherein s.sub.1 is not equal to zero. The elements may be provided with an unmagnetized portion referred to as a phantom skew. A stationary assembly is in magnetic coupling relation with the permanent magnet elements of the rotatable assembly and has t spaced teeth with adjacent teeth defining a slot therebetween, wherein t is positive integer. Each tooth has a surface adjacent the rotatable assembly having one or more notches forming a skew angle of s.sub.2 mechanical degrees with the axis of rotation. Each tooth has winding stages adapted for commutation in at least one preselected sequence. The skewed magnetic field, skewed notches and phantom magnetic skews reduce cogging between the rotatable assembly and the stationary assembly as the rotatable assembly rotates, while maintaining a back EMF waveform having a maximized flat top width.

摘要： An inside out motor includes a rotor including a concave member, a shaft defining a longitudinal axis mounted on the concave member and a magnet mounted on an interior surface of the concave member. A bearing receives the shaft for rotatably mounting the rotor. A stator assembly is mounted on said bearing and includes a bobbin mounted generally coaxially with the rotor shaft and having an interior diameter, an exterior diameter, a first axial end and a second axial end. A winding is wound on the bobbin and extends around the axis of the rotor shaft. The winding has a width in a direction parallel to the lengthwise extension of the rotor shaft. Plural separate ferromagnetic members are on each of the first and second axial ends of the bobbin. Each ferromagnetic member has a radially outer leg extending generally between the winding and the magnet. The outer legs of the ferromagnetic members on the first axial end of the bobbin extend generally from the first axial end of the bobbin toward the second axial end and the outer legs of the ferromagnetic members on the second axial end of the bobbin extend generally from the second axial end toward the first axial end. The ferromagnetic members on each of the first and second axial ends are disposed in angularly spaced, non-overlying positions around the longitudinal axis with respect to the other ferromagnetic members on the same axial end.

摘要： A motor having an external rotor, or "inside out motor" has a split C arrangement of ferromagnetic members which function as the poles of the electromagnet in the motor. The ferromagnetic members are generally C-shaped and mounted on opposite end caps of the motor. The ferromagnetic members on the opposing end caps are angularly offset from each other. The ferromagnetic members on each end cap are also spaced apart from each other, and receive a portion of the motor windings within them. The motor is constructed for assembly using few or no separate fastening devices to secure the components together. In one embodiment, a bearing core serves as the base on which all parts are assembled.

摘要： A suspension system for controlling the relative position of a vehicle and a wheel assembly supporting the vehicle for travel over a surface of terrain. The system includes a member for resiliently connecting the vehicle and the wheel assembly to establish an equilibrium position therebetween in which the vehicle is supported in a predetermined position with respect to the surface of the terrain. The system further includes a dynamoelectric machine comprising a stationary assembly and a rotatable assembly magnetically coupled thereto, the stationary assembly having a plurality of winding stages adapted to be electrically energized to apply an electromagnetic field to said rotatable assembly thereby to rotatably drive the rotatable assembly about an axis. A ball screw translates rotation of the rotatable assembly driven by the stationary assembly into linear motion between the wheel assembly and the vehicle. A control energizes the winding stages in response to deviations of the vehicle from its predetermined position whereby the vehicle is substantially maintained at its predetermined position as the vehicle travels over the surface of the terrain.
