To provide a closed type motor that can effectively cool not only a stator core but also a coil end without causing a large increase in manufacturing cost.

The canned motor 10 comprises: a stator 13 composed of a housing 11, the stator core 13A arranged in a void V surrounded by the external peripheral surface of a cylindrical can 12 and the coil end 13B; and a rotor 16 attached to an output shaft 15 in a rotor chamber 14 that is the inside of the can 12. The void V is filled with insulating oil J, an oil basin 18 and an oil feeding pipe 19 that communicates with the insulating oil J are formed at the top of the housing 11, and a small space Q is left at the upper part of the oil basin 18 when filling the insulating oil J.
