Conceptual Design of a Novel Three-Speed Geared Motor

Abstract:

The purpose of this paper is to develop a novel three-speed geared motor that integrates a basic epicyclic-type gear train with an exterior-rotor brushless DC (BLDC) motor to form a compact structural assembly. Unlike existing gear motors, the proposed device provides three speed ratios including an under drive, a direct drive, and an over drive, and is operated with a single clutch-to-clutch shaft. It provides a wider speed range than the traditional geared motor. Such an integrated design can be appropriately employed in high driving torque and low rotational speed applications or high rotational speed and low driving torque applications.
