Geared motor with planetary gear assembly

Hong-Sen Yan (Inventor)

Research output: Patent

Abstract

A geared motor includes a rotor mounted rotatably to a motor housing and having an output shaft along a rotating axis, and a stator secured to the motor housing to surround the rotor. The stator has a plurality of angularly displaced core segments with wall areas confronting magnetic pole units on the rotor, and a plurality of windings wound respectively around the core segments to create a torque so as to drive the output shaft. A planetary gear assembly includes a sun wheel mounted on the output shaft, an annulus secured to the motor housing and having an internally toothed annular surface, and a planet wheel meshing with the toothed surface and the sun wheel. A rotary member is rotated by a speed reduction drive transmitted from the planet wheel about a transmitting axis aligned with the rotating axis.
