A current command value calculating unit () calculates current command values for a rotor winding () and current command values for a stator winding () with respect to a torque command value between a first rotor () and a second rotor () and a torque command value between a stator () and the second rotor () based on an evaluation function representing a total copper loss of the rotor winding () and the stator winding () and using first and second magnetic interference models. The first magnetic interference model represents a relationship of a linkage magnetic flux &#x3a6;of the rotor winding () with respect to a current Iin the rotor winding () and a current Iin the stator winding (). The second magnetic interference model represents a relationship of a linkage magnetic flux &#x3a6;of the stator winding () with respect to the current I, I.

Information processing device, information storage device, and control device of rotary electric machine

This rotor for a rotating electric motor includes a hollow cylindrical rotor core with a plurality of laminated electromagnetic steel plates. The inner and outer circumferential surfaces of the rotor core each face a magnetic gap. The rotor core is interposed between a first rotating support member and a second rotating support member. A flange is formed on a first end of a tubular pin protruding from a first hole of the first rotating support member. A tubular expansion part of the tubular pin plastically deforms due to fluid pressure so as to come into close contact with a through hole of the rotor core, the first hole of the first rotating support member, and a second hole of the second rotating support member.

Rotor for rotating electric motor, and rotor manufacturing method

An electromagnetic coupling comprises a stator, a first rotor in which a first polar tooth and a second polar tooth are provided along a circumferential direction in an alternating manner, and a second rotor. The first rotor comprises a first polar tooth ring in which a plurality of the first polar teeth are provided along a circumferential direction with a gap therebetween, and a second polar tooth ring in which a plurality of the second polar teeth are provided along a circumferential direction with a gap therebetween, and which is placed opposing the first polar tooth ring such that the second polar teeth are placed in respective gaps between adjacent ones of the first polar teeth.
