Abstract (en)
[origin: WO2005017362A1] The invention relates to a turbomachine comprising a magnetic coupling drive. An electric driving motor transmits torque to a shaft of the turbomachine, particularly a centrifugal pump, via a magnetic coupling which is provided with axial rotors in the form of an outer rotor that surrounds an inner rotor. A hysteresis clutch is disposed between a driving motor in the form of a three-phase asynchronous motor and a turbomachine.
