Abstract: A resin molded rotor includes a rotor, a main shaft, and a resin mold. The rotor is configured to hold a magnet. The main shaft is provided with the rotor mounted thereto and is configured to transmit power to the outside. The resin mold is configured to integrally cover the rotor and part of the main shaft on respective sides in an axial direction of the rotor. An O-ring is placed between the resin mold and the main shaft to seal between the resin mold and the main shaft.

Abstract: Provided is a canned motor in which vaporization of the handling liquid is reduced in a case where a rotor rotates at high speed. A canned motor 10 includes a stator 18 disposed in a stator chamber 26, a rotor 14 disposed in a rotor chamber 12, and a stator can 7 enclosing the rotor 14. Furthermore, the canned motor 10 includes a stator chamber inlet portion 43 configured such that a cooling liquid for cooling the stator 18 flows into the stator chamber 26, and a stator chamber outlet portion 44 configured such that the cooling liquid flows out from the stator chamber 26.
