Abstract
An electromechanical transducer comprises a fixed part and a part rotatable about an axis. One of these parts includes an assembly of aircore coils which are distributed about the axis. Each coil is divided into two parts, each of which comprises two active coil segments intersected by the magnetic field upon rotation of the transducer. The two parts of each coil are furthermore arranged so that the effects of mutual inductance of the active coil segments of one coil part upon the other are reversed relative to the effects of self-inductance in each part.
