Abstract (en)
[origin: WO2009056949A2] An electric drive comprises a plurality of synchronous motors (2, 3, 4), a line (5) for powering the motors (2, 3, 4), a control unit (6) that powers the line (5) inside it to modulate supply voltage of the motors (2, 3, 4); the control unit (6) also comprises a feedback circuit (7) active between the motor (2, 3, 4) and the control unit (6) to provide the latter with data (S2, S3, S4) relating to the operation of each motor (2, 3, 4) so that the control unit (6) can modulate the voltage also as a function of the feedback data.
