Unit for measuring angular position and rotating speed, particularly the rotor of a miniature stepping motor, consisting of a system of mirrors embedded in the shaft of the rotor reflecting light beams at an angle of 90 degrees and containing an immobile impulse-rotating converter located in the plane of the mirrors, in the axis of the rotor, with which the converter is coupled by means of photo-detectors connected to a system measuring electric impulses, in particular, the converter (4) has a surface with a rotational symmetry from the inside reflecting light, on which is attached a scale, whereby on the axis (8) of the shaft (7) is located together with the light generator (1) and optical system (2, 3) of the light beam, reflected from the surface of the inside of the converter (4).<IMAGE>
