Motor with Inner Fan

A motor with an inner fan, comprising:

• a rotor that rotates with a shaft;
• a stator that opposes the outer peripheral surface of the rotor;
• an end ring that is connected to the rotor;
• stator wiring that is connected to the stator;
• a fan that rotates with the shaft through a sleeve;
• a fan guide that opposes the tip end of the blade outer periphery of the fan;
• and
• a frame that stores the rotor, the stator, the fan, the fan guide, the end ring, and the stator wiring,
• wherein the rotor includes an axial duct and a radial duct, the axial duct penetrating the rotor in the axial direction of the rotor, the radial duct communicating with the axial duct and penetrating the rotor radially from the inside to the outside of the rotor,
• the fan is an inner fan that is arranged inside the frame,
• the inner fan is of a diagonal flow type, and
• the discharge direction of the inner fan is the inward direction.
