Motor for the underwater drive of water pumps in boreholes. The bearing bushing is made from e.g. graphite or epoxy resin has rotors having coupling pins on their ends facing each other

摘要

Motor has rotors (52', 52') having coupling pins (54', 54'') on their ends facing each other. A pressure plate is arranged between the front surfaces of the coupling pins. Preferred Features: An intermediate bearing (18) is also provided and has a sheet metal packet (24) made from non-magnetizable material. A bearing bushing for the rotors is supported by the intermediate bearing and the intermediate bushing has grooves for stator windings arranged parallel to the axis.
