Abstract

PURPOSE: To provide a light-weight and inexpensive variable speed motor by containing a motor section and a predetermined variable speed mechanism section having a planetary gear in one housing.
CONSTITUTION: At least one second hole 4b is formed in parallel with a first hole 4a passed axially through the center of a rotor iron core 4 facing oppositely to a stator iron core 2 disposed in a frame 1. A planetary shaft 21 having a pair of planetary gears 24, 25 at both projected ends is rotatably supported in a second hole 4b, and a stationary gear 33 engaging in mesh with one planetary gear 24 is secured to a bracket 30. A rotary gear 34 engaging in mesh with the other planetary gear 25 is engaged with an output shaft 35, and the core 4 is rotatably supported via a pair of ball bearings 38, 39 provided on the output shaft 35. The ratio of the numbers of the teeth of the respective gears is suitably selected to thereby accelerate or decelerate, or normally or inversely rotate the gears to thereby reduce the weight of the motor.
