A canned motor has a rotor having a rotor core and a rotor can covering an outer circumferential surface of the rotor core, and a stator disposed around the rotor with a gap left therebetween for rotating the rotor, the stator having a stator core and a stator can covering an inner circumferential surface of the stator core. The stator core has a plurality of slots defined therein at circumferentially spaced regular intervals and having respective open ends opening at the inner circumferential surface of the stator core, and a plurality of windings disposed in the slots, respectively. The slots include respective winding chambers with the windings housed therein, respective constricted throats disposed radially inwardly of the winding chambers, and respective stiffener chambers spaced radially inwardly from the constricted throats. A plurality of stiffeners are housed in the stiffener chambers, respectively.
