Abstract
A canned motor equipped with a stator chamber, a load side bearing bracket and an opposite side bearing bracket on the load side and opposite side of the stator chamber. The stator chamber is formed by integrally welding a stator core, an outside can, an inside can, a load side end plate and opposite side end plate. The load side bearing bracket and the opposite side bearing bracket each includes a bearing boss supporting a radial bearing and a shaft seal thereon. The improvement consists of the end plate and the bearing bracket on the load side being integrally formed to provide a single shell structure and the inside can being welded to the bearing boss of the load side bearing bracket. By this arrangement, the number of components required for the motor is reduced, axial length of the motor is shortened and heat radiation from the end surface of the stator chamber on the load side is enhanced.
