Throttle valve body assembly with compensated control

A throttle body for a machine having a combustion engine, said throttle body comprising:

• an air circulation duct;
• a throttle valve mounted on an axis of rotation in said air circulation duct;
• a DC electric motor configured to command an opening or a closing of the throttle valve via a geartrain, the DC electric motor comprising
• a rotor having a cogging torque that oscillates with a predefined period when said rotor is driven in rotation,
• a position sensor configured to measure the position of said throttle valve, and
• an electronic control unit configured to:
• receive position values of the throttle valve measured by the sensor,
• calculate a compensation angle value for the throttle valve of between zero and a predefined period value corresponding to the predefined period of the cogging torque from a measured opening angle of the throttle valve, the predefined period value of the cogging torque, and a predetermined angle correction value for the throttle valve to correct,
• determine a value for a command signal for the electric motor from a predetermined correspondence table and the calculated compensation angle value for the throttle valve, and
• command the electric motor based on the determined command signal value.
