Disclosed is a high accuracy angular position transducer of simple constuction. The angular position transducer consists of a stator core in slots of which both exciting windings with p 1 pole pairs and output windings with p 2 pole pairs are wound, and a rotor core which carries no windings and has salient poles whose number is an integer N satisfying one of the following relations, p1+p2=N, or p1-p2=+/-N. In this construction the angular position is detected by using the following voltages induced in output windings: two or three phase voltages having a sinusoidal waveform of one cycle per rotation of 1/N of the circumference, in the combination of single phase exciting windings and two or three phase output windings; single phase voltage having a sinusoidal waveform whose phase shifts by 2 pi per rotation of 1/N of the circumference, in the combination of two phase exciting windings and single phase output windings.
