Claims

[Scope of Claim for Utility Model Registration] 1. An end ring and a rotor on the axial end face of a rotor core inserted into a rotating shaft inside a stator core formed by winding a stator winding fixed to the inner periphery of a frame. 1. An induction motor comprising a rotor integrally formed with a fan and formed of aluminum by cast molding, characterized in that another fan is attached to an end face of the rotor fan. 2. The induction motor according to claim 1 of the utility model registration claim, characterized in that the other fan has a flat mounting surface corresponding to the end surface of the rotor fan, and has an inner diameter larger than the inner diameter of the rotor fan. .
