Motor
A motor includes a rotor, a stator, a first substrate, a second substrate, and an electronic component arranged at the second substrate. The stator includes a stator core, an insulator, and a coil wound around the stator core via the insulator. The insulator includes a coupling part connected to an external device. The first substrate is fixed to the insulator. The second substrate is fixed to the first substrate. The first substrate and the second substrate are spaced apart in a rotation axis direction of the rotor.
