Abstract
A dynamo-electric machine includes a stator, a rotor disposed in the stator, a bottomed tubular case that accommodates the stator, an end cover mounted on an open end of the case, and a circuit substrate that controls driving of the dynamo-electric machine. The stator includes a core having portions that protrude toward a center of the stator, insulators mounted on the stator core, and a coil wound around each of the protruding portions with the insulators therebetween. The circuit substrate is disposed inward of an outer end of the case and is disposed between the stator and the end cover, and includes a first insulation sheet disposed between the circuit substrate and the stator to insulate the circuit substrate and the coil; and a second insulation sheet disposed between the circuit substrate and the end cover to insulate the circuit substrate and the end cover.
