摘要： In an electric rotating machine, a stator coil is comprised of first and second winding groups. The stator coil is wound around a stator core in a concentrated winding manner so that the phase difference in electrical angle between each corresponding pair of windings of the first and second winding groups is equal to π/6. Further, the windings of the first and second winding groups are connected to form Δ-Y connections. Consequently, the sixth harmonic components of the electromagnetic forces created by the windings of the first winding group can be offset by those of the electromagnetic forces created the windings of the second winding group. As a result, the total magnetic noise and torque ripple generated in the machine can be reduced. Moreover, the machine can be driven with only a single three-phase inverter to achieve the effects of reducing the total magnetic noise and torque ripple.

摘要： In a motor system, a motor includes a rotor and a stator. The rotor includes magnet poles and consequent poles. The stator includes a stator core and a stator coil that is comprised of first and second m-phase coils. The number of slots of the stator core provided per circumferentially-adjacent pair of the magnet and consequent poles is equal to 4m. The phase windings of the first m-phase coil are alternately arranged with those of the second m-phase coil in a circumferential direction of the stator core. An inverter energizes the first and second m-phase coils to cause them to respectively create first and second spatial magnetic fluxes. Variation in a resultant spatial magnetic flux, which is the resultant of the first and second spatial magnetic fluxes, is less than variations in the first and second spatial magnetic fluxes in a circumferential direction of the rotor.

摘要： A stator includes a stator-core having slots and teeth, and a back-yoke having convex and concave portions. The convex portions are partially inserted into the slots, and the concave portions receive the teeth. The teeth include tip portions whose circumferential widths become larger along a radial direction from the inside to the outside of the stator. The back-yoke includes convex portions whose circumferential widths become larger along the radial direction from the outside to the inside of the stator. The tip portions and the convex portions have substantially the same shape. The length of a joint portion between the tip portion and the convex portion, the circumferential width of the tooth corresponding to a tip surface of the convex portion, the width of a root portion of the tooth, and the circumferential width of the convex portion corresponding to a bottom face of the concave portion are substantially the same.

摘要： According to input parameters, a controller carries out: generation of a voltage command value for each of d- and q-axes; conversion of the voltage command value for each of the d- and q-axes into a voltage command value for each of the multiphase windings; and control of a multiphase inverter based on the voltage command value for each of the multiphase windings. The controller adds, to the voltage command value for the q-axis, a first compensation voltage value for compensating torque ripples to thereby output a compensated voltage command value for the q-axis. The first compensation voltage value contains m-th harmonic components in the AC motor and varies depending on the rotational angle of the rotor, the m corresponding to the number of phase of the multiphase windings. The controller uses, as the voltage command value for the q-axis, the compensated voltage command value for the q-axis.

摘要： A turn part of a lead wire includes a projection part, a slope part and a second bent part. The projection part projects from a first slot to a direction parallel to an axial direction of the stator core. The slope part is diagonally extended at an angle of less than 90 degrees aiming to a Kth slot. The Kth slot is separated from the first slot at a specific interval via a first bent part that is bent in a circumferential direction from a tip of the projection part. The second bent part is connected with the slot accommodation part accommodated in the Kth slot, and is bent to the direction parallel to the axial direction of the stator core from a tip of the slope part.
