Abstract
A motor includes a stator core, teeth respectively protruding from the stator core, and coils respectively wound onto the teeth n (n is an integer of 2 or greater) turns including first to n-th turns. Within each of ranges respectively wound with the coils onto the teeth in directions of protrusion of the teeth from the stator core, the first turn of each of the coil lies adjacent to a center of the motor. A k-th (k is an integer, 1<k≤n) turn of each of the coils lies opposite to the center of the motor. The first turn when each of the coils is cut in a corresponding one of the directions of protrusion of the teeth from the stator core is greater in cross-sectional area than each of the k-th turn and the n-th turn.
