Abstract
A stator for a rotary electric machine is provided to curb decreases in output caused by magnetic flux leakage. The stator has a stator core with stator coils that are wound around tooth parts of the stator core. The tooth parts of the stator core are arranged to form a rotational space with respect to a rotor, and housed inside the slots and cooling medium passages are formed inside the slots by blocking the openings of the slots. The protrusions are provided that protrude into the slots from both lateral surfaces of the tips of the tooth parts. The plates formed with grooves on both sides thereof that fit on the tips of the protrusions are arranged between adjacent ones of the protrusions so as to block the openings of the slots. A sealing member is formed on the rotor side of the plates.
