Abstract
A motor includes a rotor that rotates about a central axis and a stator that opposes the rotor in a radial direction. The stator includes a stator core with a core back, which has an annular shape, and teeth extending in the radial direction from the core back, bobbins each attached to a corresponding one of the teeth, and coil wires wound around the bobbins. The stator includes winding groups in which one coil wire is wound around the bobbins, and a number of poles of the rotor and a number of slots of the stator are 10 poles and 12 slots, 28 poles and 24 slots, 42 poles and 36 slots, or 44 poles and 33 slots.
