DC MOTOR

摘要

The motor is designed to have high efficiency with the different magnetizing direction on the permanent material. The motor comprises; the core (1); a coil (2) wound around the core; a permanent magnet (3) corresponding to an armature (6); a permanent magnet part magnetized in the radial direction of the motor and correspondeding to the width (Ha) of the the armature; the remainder of the permanent magnet magnetized with either the angle (20n-10)<theta<(20n+10) if the height ratio between the permanent magnet and the armature (n) is 1<n<1.75 or the angle (20n-10)<theta<45 when n is 1<n<1.75.
