A turbine engine rotor blade angle control device comprising an electric motor with a fixed stator (5) and a rotor (7), preferably an asynchronous or permanent magnet rotor, which is attached to the turbine engine shaft (2) and rigidly connected to a gear wheel (8) engaging pinion segments (9) secured to the root (4) of each blade (1). The device further comprises means for locking the root (4) of each blade (1), positioned by an electromechanical actuator (13) rigidly connected to the shaft (2), and electrically powered via a rotary transformer (25). |
