Abstract
A dynamo-electric machine reduces the increase in temperature of a stator close to a cooling liquid outlet and a stator end portion, and that has excellent cooling performance. The dynamo-electric machine is provided with: a stator, a rotor that is held on the inner-diameter-side of the stator across a predetermined gap so as to be capable of rotating; and a housing that is located on the outer-diameter-side of the stator and holds the stator and the rotor. The housing is provided with a cooling liquid channel through which a cooling liquid flows, the radial height of the cooling liquid channel within the housing differing depending on the axial position of the rotor.
