  • Patent number: 11670991
    Abstract: In an electric driving apparatus, a first rotational angle detecting sensor that generates a signal that corresponds to rotation of a shaft is disposed between a controlling apparatus and a motor. A housing accommodates the motor, the controlling apparatus, and the first rotational angle detecting sensor together. A second rotational angle detecting sensor that generates a signal that corresponds to rotation of the shaft is disposed at a position that is further away from the motor than the controlling apparatus in the axial direction of the shaft, and is disposed outside the housing. The first rotational angle detecting sensor is a magnetic detecting element sensor that includes: a magnet rotating body that includes a magnet, and that rotates together with the shaft; and a magnetic detecting element that detects magnetism from the magnet. The second rotational angle detecting sensor is a resolver.

  • Patent number: 11418070
    Abstract: Phase coils include a first phase coil and a second phase coil, the phase coils are configured by connecting together end portions of the coil terminals of the first phase coil and the second phase coil that extend outward from identical radial positions in the slots axially outside the stator core so as to be radially outside a coil end group, and the coil terminals of the first phase coils of the phase coils of three phases include joint coil portions that extend outward from the slots within a pitch of one magnetic pole, are then bent so as to extend in an identical circumferential direction, and are placed in close proximity to the end portions of the coil terminals of the second phase coils that are intended for connection therewith.
