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 method of operating a laundry machine. The machine has a pair of rotatable components and is driven by an electronically commutated motor having a stationary assembly with a plurality of winding stages and also having a rotatable assembly adapted to be selectively coupled to at least one of the rotatable components. In this method, a DC voltage for application to the motor is received, and a first control function is imposed on the operation of the machine to control the application of the DC voltage in accordance with a selected one of a plurality of first waveshapes so as to provide a resultant effective voltage to the motor. A second control function is imposed on the operation of the machine through the controlled application of the DC voltage to selectively set the maximum amplitude of the effective voltage, and the winding stages are commutated by applying the effective voltage thereto in sequence whereby the first and second control function jointly determine the angular velocity of the at least one rotatable component.A laundering apparatus, a control system for an electronically commutated motor, and a method of operating an electronically comutated motor are also disclosed.

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.
