  • Patent number: 11920673
    Abstract: An electric drive apparatus includes a rotating electric machine and a transmission. The rotating electric machine includes a rotor, a stator and a first housing. The transmission includes a motive power transmitting unit, a second housing provided integrally with the first housing, and lubricating oil provided in the second housing to lubricate the motive power transmitting unit. The stator includes a stator coil that has first and second coil end parts respectively protruding from first and second axial end faces of a stator core. Each of phase windings of the stator coil has turn portions included in the first coil end part and joints included in the second coil end part. The second coil end part is located on the same axial side of the stator core as the transmission whereas the first coil end part is located on the opposite axial side of the stator core to the transmission.

  • Patent number: 11539254
    Abstract: An electric drive apparatus includes a rotating electric machine and a transmission. The transmission is provided, on one axial side of the rotating electric machine, integrally with the rotating electric machine. The rotating electric machine includes a stator coil that is assembled to a stator core to have first and second coil end parts respectively protruding from first and second axial end faces of the stator core. The axial protruding height of the second coil end part from the second axial end face of the stator core is larger than the axial protruding height of the first coil end part from the first axial end face of the stator core. The first coil end part is located on the same axial side of the stator core as the transmission whereas the second coil end part is located on the opposite axial side of the stator core to the transmission.

  • Patent number: 11110793
    Abstract: A rotating electrical machine includes a cylindrical rotor and a cylindrical stator. The rotor includes a magnet portion. The stator includes a multiple-phase stator winding. The rotor and the stator are arranged in a state in which the magnet portion and the stator winding oppose each other inward and outward in a radial direction. A differential apparatus includes a differential case, side gears, and a pinion gear. The differential case rotates with a rotation of a rotor. The side gears are housed in the differential case and respectively connected to the pair of axles. The pinion gear is housed in the differential case and mutually meshes with the side gears. The differential apparatus is concentrically arranged with the rotor in a hollow portion provided on an inner side in a radial direction of a magnetic circuit portion configured by the rotor and the stator in the rotating electrical machine.
