Abstract

Provided are a commutator motor having a cooling wind path for improving an effect of cooling a stator and a rotor, and an electric motor using the commutator motor. A stator coil (4f), which is wound through a magnetic pole core portion (4c) is molded with a thermosetting resin. The resin-molded stator coil (4f) has a step difference portion (13) between an outer surface (3h) of a rotor core (3a) and an inner surface (4h) of a yoke core portion (4b). The step difference portion (13) faces a cooling wind path (10) and imparts a difference to the thickness of the stator coil (4f) in a radial direction of a rotation shaft (3d).
