摘要： A fastening structure for a ring-gear and a differential case comprises a differential case which is provided with: a ring gear having a gear section formed on the outer peripheral surface thereof, and a plurality of notch portions formed on the inner peripheral surface thereof; a press-fitting surface whereon the ring gear is press-fitted; and a flange section which is forced against and caulked to the notch portions, at the end of the press-fitting surface. After the ring gear has been press-fitted to the press-fitting surface, the flange section is forced toward the notch portions, and thus the differential case is caulked and fastened to the ring gear. The notch portions have stepped surfaces, and thus rattling generated during torque transmission can be suppressed.

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 rotary electric system, a switch member includes at least one of a first switch and a second switch. The first switch is connected between a neutral point of multiphase stator windings and a high-side electrode of a direct current power source. The second switch is connected between the neutral point and a low-side electrode of the direct current power source. A controller works to turn the switch member off and on thereby switching control of the multiphase inverter between full-wave driving mode and half-wave driving mode. The full-wave driving mode allows the controller to drive all of the high-side and low-side switching elements per phase of the multiphase stator windings. The half-wave driving mode allows the controller to drive any one of the high-side switching element and the low-side switching element per phase of the multiphase stator windings.
