Split-ring electric motor for pump - has feeder coupled to pump chamber at point exhibiting high pressure

摘要

The motor has a double-walled split ring (13, 14) with a hollow space (17, 20) between the inner and outer walls, through which a cooling medium is passed. The pumped medium may be used as the cooling medium for the electric motor, with feed and return connections (18, 19) coupled to the pump chamber (2). Pref. the feed connection (18) is coupled to the pump chamber (2) at a point of exhibiting a high press. The return connection (19) is coupled to the pump chamber (2) at a point exhibiting of low press. ADVANTAGE - Simplified mfr., maintenance, and repair.
