<p>A compact miniature motor includes a DC motor (10), a worm gear (32), a pinion transfer gear (34), at least one cluster gear (48), an output gear (56), and an output shaft (52). The gears form a gear train that wraps tightly around the DC motor (10) in the shape of a capital letter J. Inverted trunnions (40, 42) stabilize the pinion transfer gear by extending longitudinally inside thereof. Acoustical chambers (70) packed with grease suppress noise generated by the gear train. A PC board (22) is also provided and has components for rectifying, filtering for constant DC, and modifying AC voltage before passing it to energize the DC motor (10). The output shaft (52) may drive either an ice crusher in a refrigerator or a product mover for beverage cans inside a vending machine or another type of electromechanical unit requiring application of high torque.</p> |
