A circulation pump is an integrated unit, consisting of a hydraulic part for transmitting energy to the medium and a driving canned electric motor. The strict efficiency standards for circulation pumps set by the European Union led to the fact, that today synchronous motor with cost-intensive and resource critical rare earth magnets are state of the art. This paper presents a new resource saving design for canned motors of circulation pumps based on a novel separation can in combination with a ferrite assisted synchronous reluctance motor.
