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.
