Abstract
An electromecanic transducer comprises a stator 4 formed of three parts 6, 8 and 18 each presenting merlons or teeth 52, 54 and 60 superposed to a multipolar magnet 34 of rotor 30. Three statoric magnetic poles 10, 12 and 20 are situated in a same statoric plane and define, together with two branches 22 and 24 each containing a coil 26 and 28, two principal magnetic circuits of the transducer. The transducer is particularly suitable for a step functioning, in particular when a relatively high number of steps per turn is desired.
