Abstract

A motor includes a stator, and includes a first substrate and a second substrate mounted on the stator. The stator has a stator core in a ring shape and a first coil of a first phase and a second coil of a second phase wound around the stator core. The first substrate includes a first power supply wiring to supply electric power to the first coil. The second substrate has a second power supply wiring to supply electric power to the second coil.
