Abstract (en)
The disclosure refers to an apparatus (1) for controlling the rotational speed of a shaft (2) of a pneumatic motor (3) to a desired speed and its use. The apparatus (1) comprises: - means (4, 5) for detecting the current rotational speed of the shaft (2), for example a Hall sensor device; - means (6) for varying a flow rate of air through the pneumatic motor (3), for example a solenoid valve disposed in an air intake (8) of the motor (3); and - electrically operated means (7) for automatically controlling the variation means (6) in response to the detected current rotational speed of the shaft (2) and depending on the desired speed, including for example a CPU.
