ABSTRACT:
A miniature electric rotating machine has a stator equipped with a field pole on a peripheral circle of a rotor, and the field pole is constituted by a permanent magnet. Each permanent magnet of a miniature electric rotating machine of this type can be divided into a magnetizing side and a demagnetizing side with respect to armature reaction. In the permanent magnet of the present invention, an end portion on the demagnetizing side, which has directivity different from the magnetizing directions on the magnetizing and demagnetizing sides, is disposed adjacent to the portion on the demagnetizing side.
