A compact miniature motor includes a DC motor, a worm gear, a pinion transfer gear, at least one cluster gear, an output gear, and an output shaft. A socket may be used to accept the output shaft. The gears form a gear train that wraps tightly around the DC motor in the shape of a capital letter J. Inverted trunnions stabilize the pinion transfer gear by extending longitudinally inside thereof. Acoustical chambers packed with grease suppress noise generated by the gear train. A PC board is also provided and has components for rectifying, filtering for constant DC, and modifying AC voltage before passing it to energize the DC motor. The output shaft may drive a product mover for beverage cans inside a vending machine or another type of electromechanical unit requiring the application of high torque. |
