PURPOSE:To reduce the abrasion of the coil insulating layer of a stator coil due to thermal expansion or contraction, by forming slot liners with the two layers of a coil side slot liner on the stator coil side and a core side slot liner on the stator core side. CONSTITUTION:A stator is provided with a stator core 1, a stator coil 2 inserted into the slot of the stator core 1, slot liners 3a inserted between the stator core 1 and the stator coil 2, and the like. The slot liners 3a are formed with the two layers of a coil side slot linear 3a1 on the stator coil 2 side and a core side slot liner 3a2 on the stator core 1 side. Slots 9 are arranged on the wall surface of the coil side slot liner 3a1, and the wall surface is treated with lubricant 10. As a result, the abrasion of the coil insulating layer of the stator coil due to thermal expansion or contraction is reduced.
