Abstract

A motor includes a rotor including a shaft that extends axially, a stator that surrounds the radial outer side of the rotor and includes coils defined by windings of coil wires, a holder with through-holes that is axially above the stator for insertion of the coil wires therethrough and extends axially, and a substrate that is axially above the holder and includes an electronic component mounted thereon. Only some of the coil wires with the same phase are inserted into each of the through-holes, and the through-holes are separate holes provided to different phases of the coil wires.
