ABSTRACT:
A support for the rotor shaft of a centrifugal pump with permanent-magnet electric motor. The motor is of the type which comprises a laminate-pack stator with a coil-like winding and a rotor placed in a cylindrical chamber which is separate from the stator, the rotor being rotatable about the shaft which is fixed axially therein. The support is characterized in that it comprises a tubular shank which extends from the bottom of the chamber and in which one end of the shaft is force-fitted. The bottom has a through hole at the shank.
