摘要： A magnetic gear comprises a first permanent magnet field having a plurality of permanent magnet magnetic poles, a second permanent magnet field having a plurality of permanent magnet magnetic poles, number of poles of which magnet is different from that of the first permanent magnet field, and a modulating magnetic pole arranged between the first permanent magnet field and the second permanent magnet field and having a plurality of pole pieces to modulate the number of poles of the first and second permanent magnet fields. Non-magnetic bars are provided between the plurality of pole pieces. One ends of the non-magnetic bars are fixed to a first non-magnetic end holding member and the other ends of the non-magnetic bars are electrically insulated from and fixed to a second non-magnetic end holding member.

摘要： A stator and a rotor are oppositely arranged having a gap between the stator and the rotor in a direction parallel to a rotary shaft. The rotor has permanent magnets forming field magnetic poles and soft magnetic material segments to cover at least stator-facing surfaces of the respective permanent magnets. Each of the soft magnetic materials forms a composite part together with the permanent magnet. The rotor further has a disc-shaped nonmagnetic molded frame molded so as to cover the periphery of the composite part including the permanent magnet and the soft magnetic material segment while leaving a stator-facing surface of the soft magnetic material segment as an exposed surface. The composite part (including the permanent magnet and the soft magnetic material) and the nonmagnetic molded frame are integrated by molding of the molded material.

摘要： In a punch die for powder compacting, a powder compacting equipment equipped with the punch die, and a forming method with the equipment, for suppressing the occurrence of stress concentration in the die without changing a shape of a powder compacting body, the punch die is used to form a cylindrical member by powder compacting, which has a substantially cylindrical shape and has a protrusion portion formed on the inner peripheral side thereof to protrude in the axial direction or a stepped portion or a concave portion formed on the inner peripheral side thereof in the radial direction. The punch die has a substantially cylindrical shape, and has a protrusion portion formed on at least a part of the inner peripheral surface or the outer peripheral surface thereof to protrude toward the center axis. The punch die is divided into two upper and lower parts at a surface forming the same surface as a lower surface of the protrusion portion, and the division surfaces are mechanically connected to each other or adhered to each other by adhesive.
