The rotational velocity-type transducer comprises a permanent magnet (1), which is fabricated as a disk provided with poles alternating circle-wise and with an axial opening (2) adapted for a rotary shaft (3). In front of the poles of the permanent magnet (1) there are disposed electronic conductors (7a) of a winding (4a) arranged on a base, which electronic conductors are connected in series through the frontal portions (8a) of the winding (4a). Just like the winding (4a), there is arranged a winding (4b) of which the electronic conductors (7b) and the frontal portions (8b) are mounted closely to the electronic conductors (7a) and the frontal portions (8a) and so that they form the displacement therebetween in the range from 30 to 330 electrical degrees. The taps of the windings (4a, 4b) are connected to a differential amplifier (9) whilst their other taps are linked with a common bus (10) of said amplifier (9). |
