CANNED ELECTRIC ROTATING MACHINE

摘要

A canned electric rotating machine is used in an electric motor for driving a seal-less pump (non-seal pump) having a rotor chamber (15) filled with a high-pressure pump working liquid. The canned electric rotating machine includes a cylindrical frame (11), a stator (17) having a stator core (17a) and a stator winding (17b) and housed in the cylindrical frame, a can (21) configured to enclose the stator (17), and a rotor (20) rotatably provided in a space surrounded by the can (21). The can (21) is composed of a single layer of fiber-reinforced plastics comprising one resin of polyether ether ketone (PEEK), polyimide (PI), polyester amide imide, polyhydantoin, isocyanurate denatured polyester imide, polyamide-imide, polyester and epoxide, which is reinforced with carbon fiber or glass fiber or aramid fiber.
