Abstract
A dynamoelectric machine main body, power circuit modules and a field circuit module, and a control apparatus that has a heatsink that is prepared by die casting, and that is mounted integrally onto the dynamoelectric machine main body are included, the heatsink including a plurality of convex heat receiving portions that are disposed so as to project from a front surface of a base plate, and that have heat receiving surfaces, the power circuit modules and the field circuit module including seal main body portions that are constituted by an electrically insulating resin that seal switching elements so as to expose bottom surfaces of element heat radiating portions on reference surfaces that have a surface shape that corresponds to a shape of the heat receiving surfaces, and electrical insulation supporting layers being interposed between the bottom surfaces of the heat receiving surfaces and the element heat radiating portions.
