Claims

[Claims for Utility Model Registration] 1. In a permanent magnet motor using permanent magnets as field magnets, an inner core is formed into a polygonal column shape, and a field magnet directed to one piece is placed on each side of the inner core. A permanent magnet motor having fixed magnets, characterized in that the bottom surface of the field magnet is flat and the top surface is formed into an arcuate convex curved surface. 2. In a permanent magnet motor that uses permanent magnets as field magnets, the inner core is formed into a polygonal column shape, and one field magnet is fixed on each side of the inner core. A permanent magnet characterized in that the bottom surface of the magnet is flat, the top surface has an arcuate convex curved surface in the central part and part of the part adjacent thereto, and both sides further outside the central part are flat. motor. 3. In the permanent magnet motor according to claim 1 or 2, a skew groove is formed in the inner core by arranging the center axis of each field magnet at a predetermined angle with respect to the center axis of the motor and fixing it to the inner core. A permanent magnet motor characterized by:
