ABSTRACT:
A rotation support has improved thrust-bearing for rotors of electric motors of synchronous pumps. The rotation sup: a stator of the electric motor, in which a hollow body is housed for supporting and containing a permanent magnet rotor, an impeller being kinematically coupled with a shaft of the electric motor, as well as opposite supports of the shaft, one of which is provided with axial thrust-bearing. Advantageously, the support provided with thrust-bearing comprises a bush of antifriction material facing a side of the rotor and which has an axial abutment placed directly in contact with this side of the rotor.
