<p>This invention relates to a DC motor having a balancing effect. It uses a permanent magnet as a convex-type magnet pole. The armature is made to be a layered structure of convex pope, so that the armature can be operated in an intense magnetic field, and the electromagnetic loss can be reduced. Further, thermal loss is significantly reduced, whereby the electric energy can be saved by more than 60 %.</p> |
