摘要： Disclosed is a structure for fastening a ring gear to a differential case. The ring gear has a gear-side press-fit face annularly formed thereon, a projected portion located at an inner position relative to the gear-side press-fit face, and a notch portion located opposite to the gear-side press-fit face across the projected portion. The differential case has a case-side press-fit face which is annularly formed thereon and over which the gear-side press-fit face is press fitted, a caulk portion which is smaller than the case-side press-fit face in outer diameter and caulked to the notch portion, and a case-side smooth face which contacts the projected portion to position the ring gear with respect to the differential case. This arrangement serves to reduce the differential case in size.

摘要： Disclosed is a ring gear fastening structure in which a ring gear is fastened to the flange of a differential case configuring a differential sub-assembly. The inner circumferential surface of the ring gear is press-fitted into the outer circumferential surface of the flange, and the ring gear is swaged by means of a swage part which is disposed on at least one end of the flange in the axial direction. The inner circumferential surface of the ring gear is formed with a circumferential groove which extends in the circumferential direction of said inner circumferential surface. The circumferential groove is disposed facing the outer circumferential surface of the flange.

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.
