The electric drive is a three-phase squirrel-cage induction motor with the stator and rotor sealed in thin stainless-steel cans which prevent the process fluid from coming in contact with the stator or rotor windings. The cans are supported by the laminations to contain the system pressure of 2000 psi. The motor is enclosed in a heavy pressure vessel which is designed to hold the full system pressure in the event of a can failure. The motor and bearings are cooled by the use of a small auxiliary impeller.
