摘要： A rotating electric machine has a drive control part and a motor having a stator and a rotor. The drive control part has an external disturbance voltage instruction generation part, a switching signal generation part, first and second drive circuits, a current acquisition part detecting an external disturbance current flowing in three phase winding in each of a first coil and a second coil of the stator, and a phase angle estimation part detecting a phase angle of the rotor of the motor based on the detected external disturbance current. The drive control part adjusts turn-on/turn-off timings of switching signals so as to reduce a timing difference between corresponding line external disturbance voltages in the three phase windings more than the time difference without performing the timing adjustment while maintaining a duty ratio of these line external disturbance voltages to that when the timing adjustment is not performed.

摘要： In a control apparatus, an interference-reduction current calculator calculates, as an interference reduction current, a component of a current vector in a coordinate axis in a rotating coordinate system defined with respect to a rotor of the rotary machine. The current vector flows in the rotary machine, and the coordinate axis serves as an interference reduction coordinate axis in which the component of the current vector has reduced interference from change of the phase of the output voltage vector. An amplitude setter sets, as a manipulated variable for feedback controlling the interference reduction current to a command current value based on a command value for a controlled variable, one of: an amplitude of the output voltage vector, and an amplitude parameter indicative of a component of the output voltage vector. The component of the output voltage vector depends on the amplitude of the output voltage vector.

摘要： At least one of conditions are satisfied, the conditions are a condition that directions of vectors of N sets of first pulse voltages are different from each other, a condition that directions of vectors of N sets of second pulse voltages are different from each other, and a condition that directions of vectors of N sets of third pulse voltages are different from each other. Further, periods in which voltages having different directions of the vectors among the N sets of the first, the second and the third pulse voltages, are applied at least partially overlap with each other.

摘要： In a rotary electric machine, a rotor, and a stator. The stator includes slots provided in a circumferential direction thereof, and stator windings wound in the slots. The stator windings include n groups of three-phase windings, where n is a power of 2. The slots include first slots each accommodating portions of same-group and same-phase windings in the n groups of three-phase windings. The energizing directions of the same-group and same-phase windings are identical to each other. The second slots each accommodate different-group and same-phase windings in the n groups of three-phase windings. The first slots and the second slots are arranged in the stator at predetermined intervals in a circumferential direction of the stator, and the three-phase windings of each group are wound around the stator with regular intervals therebetween.
