Abstract

PURPOSE: To raise the torque of a DC motor and make it compact, by providing second annular permanent field magnets magnet around first permanent field magnets.
CONSTITUTION: The first and the second permanent field magnets 4, 5 are mounted on a bottom memeber 6 so that these magnets are located symmetrically as to a shaft. The first magnets 4 are magnetized in the axial direction of the motor. The second magnets 5 are fitted in the cylindrical part of the bottom member 6 and located around the first magnets 4. The same poles of the first and the second mane magnets face each other. This results in raising the torque of the shaft and reducing the size of the motor.
