  • Patent number: 11196312
    Abstract: A motor includes a stator including a stator core and teeth respectively protruding from the stator core in predetermined directions of protrusion, and coils respectively wound onto the teeth n (n is an integer of 3 or greater) turns including first to n-th turns. A k-th (k is an integer, 1<k<n) turn of each of the coils lies at a center of a range wound with each of the coils onto the teeth in a corresponding one of the directions of protrusion of the teeth from the stator core. Each of the first turn and the n-th turn when each of the coils is cut in a corresponding one of the directions of protrusion of the teeth is greater in cross-sectional area than the k-th turn.
