摘要：
A canned motor for use in a pump has an outer frame casing fitted over a stator, a pair of side frame members welded to respective open ends of the outer frame casing, a can fitted in the stator and joined to the side frame members, and an outer cylinder disposed around the outer frame casing with an annular spaced defined therebetween, the outer cylinder being welded to the outer frame casing. The outer cylinder has a pair of flanges disposed respectively on axially spaced open ends thereof for attachment to components of a pump assembly and holding a fluid being handled within the outer cylinder. The outer cylinder has a hole defined in an outer circumferential wall thereof for passing leads for connection to a power supply.
