Filed:

Apr 6, 1992

Appl. No.:

07/863900

Inventors:

David M. Erdman - Fort Wayne IN
Dale F. Yoder - Fort Wayne IN
Richard S. Tatman - Fort Wayne IN
David T. Molnar - Fort Wayne IN

Assignee:

General Electric Company - Schenectady NY

International Classification:

H02K 106

US Classification:

310217, 310254, 310 68 B, 310194, 310156, 310 90, 310 89, 318794

Abstract:

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.
