<p>The system (100) has mechanical transmission units (20) arranged between a blade (10) and a rotary shaft (28) of a brushless electric machine i.e. electric motor (30). A control unit (32) is operated along a pitch adjustment mode in which blade coupling units (31) occupy a deactivated configuration and the machine occupies a motor configuration. The control unit is operated along a power generating mode in which the coupling units occupy an activated configuration and the machine occupies a generator configuration. An independent claim is also included for a fan comprising a driving shaft for driving a fan disk centered on a longitudinal axis.</p> |
