Abstract

A canned motor pump has a can separating the rotor and the fluid compartment of the pump from the stator. The stator winding is affixed to a winding carrier which is shoved over and in heat-conducting relation with the can. The casing carries the electronic circuitry for commutating the motor and this circuitry is connected with the stator winding via a plug connector on the carrier.
