Abstract
PURPOSE: To provide an electromagnetic drive machine which has small size and high output power by providing a permanent magnet member having special shape and poles and electromagnets in a casing for surrounding a rotor having permanent magnet pieces magnetized in special state.
CONSTITUTION: Assuming that one pole of a magnet is called an "α pole" and the other is called a "β pole", predetermined number of permanent magnet pieces 3 having α pole at the outer peripheral side are provided on the peripheral edge of a rotor 2 coaxially secured with an output rotary shaft 1. A predetermined number of electromagnets 5 in which the α pole is disposed at the rotor 2 side are provided within the casing 4 for surrounding the rotor 2, and arcuate permanent magnet members 6 in which the α pole is provided on the inner peripheral side are so disposed that the thickness H is gradually reduced along the rotating direction M of the rotor 2. When the intermediate point P of the piece 3 is disposed at the position slightly passed through the central point Q of the electromagnet 5, the electromagnet 5 is energized to repel and move the permanent magnet 3 from the thick portion of the adjacent permanent magnet member 6 and then deenergized.
