摘要： The invention aims at providing a forced cooling rotary electric machine capable of bringing temperature distribution close to a designed temperature distribution and avoiding becoming a larger size, and employs a wedge formed with ventilation grooves and a wedge not formed with the ventilation grooves to regulate the flow rates of cooling gas passing through air ducts, so that the cooling gas supplied to a part of a stator core, in which temperature is low, can be caused to flow positively to a part in which the temperature is high and the temperature distribution in the axial direction of the stator core can be uniformized. As a result, the temperature distribution in the axial direction of the stator core can be brought close to a designed temperature distribution, and a forced cooling rotary electric machine that need not be made larger in size with a margin can be obtained.
