    摘要： An energy efficient low-power integral electronically commutated fan motor and control circuit assembly mounted on a circuit board for use in refrigerators utilizing a Hall sensor to provide positional control signals for sequential energization of the windings with the Hall sensor energization being pulsed, and the motor stator windings energized only during a portion of the period, when rotational torque produced by the energization is greatest in order to reduce the power input to the assembly. Integrally molded multi-function components including the coil bobbin, ground pin, Hall sensor holder, motor bearing oil well covers, and assembly housing provide positioning, support, and securing assistance along with electrical and magnetic operative connections and positioning. A capacitively coupled bridge power supply is provided to further reduce power consumption, and the motor is protected under fault and stall conditions by a current limiting circuit and a timed retry circuit, and the rotor and stator are designed for adequate starting torque in a refrigerator. Power is supplied to the motor windings through a voltage dropping capacitor connected in series therewith.

    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： 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 permanent magnet rotor includes a core and a plurality of magnetizable elements held about the outer circumferential surface of the core, as by an adhesive. The core and magnetizable elements are cold-pressed into a deep drawn cup-shaped outer metallic shell having a substantially closed end wall and an opposite open end defined by a peripheral edge which is rolled over the periphery of an end plate to encapsulate the core and magnetizable elements within the shell. An insulator disk is preferably disposed between each end of the core and the adjacent shell end wall and end plate. The permanent magnet rotor may be formed by a methond and apparatus that cold press the core and magnetizable elements into the cup-shaped shell and form the peripheral edge of the shell over the end plate to effect encapulation.

    摘要： A dynamoelectric machine having a rotor constructed to facilitate position sensing and a stator constructed to retain slot liners in the stator while reducing flux leakage between adjacent teeth of the stator. The rotor includes permanent magnets which project beyond one axial end of the rotor and the stator. Thus, a position sensor may be positioned in registration with the overhanging portion of the magnet. Slots in the stator are shaped to hold an insulating slot liner in the slot, and prevent the liner from slipping into the stator bore. The slots are also angularly formed near their inner ends to increase the space between adjacent stator teeth for reducing the flux leakage between the teeth.
