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 dynamoelectric machine having a wire retaining device constructed to frictionally retain the quadrature winding to allow automated winding of the quadrature winding. The wire retaining device includes stator end caps having integrally formed wire retention elements at the radially inner end of the stator tooth. The wire retaining device frictionally holds the wire in place as the quadrature winding is automatically wound about the stator. In addition, the stator end caps electrically insulate the quadrature winding from the stator and the main winding.
