摘要： A rotary electric machine control system includes a control device that controls a rotary electric machine. When there is a current phase at which a reluctance torque is maximum between a first current phase (Θ1) of a first current vector (I
1 ) on which current pulses have not been superimposed yet and a second current phase (Θ2) of a second current vector (I
2 ) obtained by increasing a d-axis current and reducing a q-axis current, the control device sets an intermediate current vector (Im) having an intermediate phase (Θm) between the first and second current phases (Θ1, Θ2). The intermediate current vector (Im) is set so as to be larger than an imaginary current vector (Ima) at the intermediate phase (Θm) in the case where a vector locus is varied in a straight line from the first current vector (I
1 ) to the second current vector (I
2 ). The current pulses are generated by changing the current vector in order of I
1 , Im and I
2 and returning the current vector in order of Im and I
1 .

摘要： A rotor for a rotating electrical device includes: a rotor coil that is wound on each of the rotor salient poles; a retaining member that is supported by a rotor core; and an outer magnetic member. The retaining member has a beam bridged between the adjacent rotor salient poles and prevents the rotor coil from falling out. The outer magnetic member is provided in an end of the beam.

摘要： A rotor (14) of a rotary electric machine includes a rotor core (14) having a plurality of rotor salient poles (32n, 32s) that are disposed on an outer periphery of the rotor core in a circumferential direction of the rotor core, rotor coils (28n, 28s, 30n, 30s) wound on the rotor salient poles (32n, 32s), and a retainer member (50) provided so as to close a slot (34) formed between the rotor salient poles (32n, 32s). The retainer member (50) includes a leg portion (52) that extends radially in the slot (34) between rotor coils wound on two rotor salient poles (32n, 32s) adjacent to each other in the circumferential direction and is fixed to the rotor core (24), and beam portions (54) that extend in the opposite circumferential directions each other from a radially outer end portion of the leg portion (52) and that close an outer periphery of the slot (34). The leg portion (52) of the retainer member (50) is provided with protrusion portions (56) protruded in circumferential directions to engage with the coil winding that forms the rotor coils (30n, 30s).

摘要： A plurality of salient poles (19) projecting toward a stator (12) are arranged on a rotor core (16) along the circumferential direction while being spaced apart from each other, and rotor windings (18n, 18s) are wound around these salient poles (19). The rotor windings (18n, 18s) are short-circuited through diodes (21n, 21s), respectively; and when currents rectified by the diodes (21n, 21s) flow through the rotor windings (18n, 18s), the salient poles (19) are magnetized to produce a magnet where the magnetic pole is fixed. The width θ of each salient pole (19) in the circumferential direction is smaller than a width corresponding to an electric angle of 180° of the rotor (14), and the rotor windings (18n, 18s) are wound around each salient pole (19) by short-pitch winding.
