  • Patent number: 10164487
    Abstract: A motor includes a rotation shaft, a stator, and a rotor. The stator includes an armature winding and a stator core including a main core portion with an axial stack of core sheets and a magnetic plate on an end thereof. Each core sheet includes a tooth formation portion around which the armature winding is wound. The magnetic plate includes a stacked portion and an axially extending portion. The stacked portion stacked on the axial end of the main core portion and includes an end located toward the rotor. The axially extending portion extends toward the outer side in the axial direction from the end of the stacked portion located toward the rotor and is opposed to the rotor in a radial direction of the motor. The axially extending portion is shaped to be magnetically skewed in a circumferential direction relative to the tooth formation portion and the stacked portion.

  • Patent number: 8916999
    Abstract: A motor includes a motor case, and a rotor and a stator, which are disposed in the case. The case has a tubular portion, a front cover mounted to an axial end of the portion, and a rear cover mounted to the other axial end of the portion. The rotor has a rotary shaft and the stator includes a plurality of teeth, which extend toward a central axis of the shaft and are circumferentially disposed at equal intervals. Between each circumferentially adjacent pair of the teeth, a slot extending toward the axis is formed. In each slot, a U-shaped segment is inserted in parallel with the axis. The distal ends of the segments projecting out from the slots are electrically interconnected, thereby forming an SC coil including the segments disposed circumferentially. The SC coil includes a receiving terminal, and the terminal includes leads extending in parallel to the axis.
