Abstract: A brushless motor comprising: a rotor; a stator core disposed at a radial direction outside of the rotor, and a stator case. The stator core includes an outer ring shaped section, teeth sections projecting out from the outer ring shaped section toward a radial direction inside, and an inner ring shaped section extending from end portions of the teeth sections. Protruding portions are formed at the outer ring shaped section so as to project toward a radial direction outside and so as to be disposed at even intervals around a circumferential direction of the outer ring shaped section. The stator case is integrated together with the stator core by a plurality of plastic deformation portions formed at an outer peripheral portion of the stator case at locations facing towards the protruding portions, and the plastic deformation portions are disposed at even intervals along a circumferential direction of the stator case.

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.
