Electric actuator apparatus equipped with position detection system and related road vehicle

1) An electric actuator apparatus (6) comprising:

• an electric motor (7), comprising in turn a stator (8) and a rotor (9), which is configured to rotate about an axis (A) according to the power transmitted by the stator (8);
• a control unit (10) configured to control the electric motor (7) via a feedback control;
• a position detection system (11) configured to provide the control unit (10) with an angular position of the rotor (9);
• the electric actuator apparatus (6) being characterized by further comprising:
• a reading portion (13), which is integral to the rotor (9) and provided with an encoded surface (14) on which a plurality of codes (15) that can be associated with the angular position of the rotor (9) are fixed;
• an optical or laser sensor element (16), which is arranged integral to the stator (8) and so as to point toward the encoded surface (14)
• the sensor element (16) comprises one or more single-photon, SPAD photodetector (17) diodes.
