Abstract
An electric motor has a rotor, stator, and covers. A stator coil is a pre-wound coil inserted into slots of a stator core from its inner side. A no-lead-wire side coil end portion of the stator coil protrudes radially inward. A no-lead-wire side coolant chamber is liquid-tightly defined by the cover covering the no-lead-wire side coil end portion and a seal plate(s) that is attached from or on a radially inner side of the stator core so as to cover an opening between the inner peripheral edge of the cover and the inner peripheral edge of the stator core.
