Claims

[Scope of utility model registration request]

An armature shaft, an armature core attached to the armature shaft, an armature coil attached to the outer periphery of the armature core, a magnetic frame supporting the armature shaft, and a magnetic frame. A vehicular electric motor having a partially opened wind intake for forcing cooling air from outside, provided with a duct having one end open to the wind intake and the other end communicating with the inside of the armature core, A vehicle electric motor characterized in that the duct allows cooling air to flow into the ends of the armature core and armature coil.
