Abstract (en)
A device for controlling and regulating the relative speed between the scroll (4) and drum (2) of a centrifugal extractor, comprising a dc or ac electric motor (10), stator (10a) of which is made integral with drum (2) and rotor (10b) of which is made integral with a gear (7) which drives scroll (4) via appropriate means (7a, 8a, 14a; 7b, 8b, 14b) of connection, there being furthermore provided means (30a, 30b) for detecting the speeds of rotation of such rotor (10b) and stator (10a) and for converting them into a representative electric signal, and means (40, 50) for comparing such electric signals designed to emit a signal (Drs) capable of operating means (60; 1060) for supplying to rotor (10b) a current capable of compensating for any deviations of the parameters of the extractor from the programmed operating conditions. <IMAGE>
