Abstract

PURPOSE:To improve the accuracy in a simple structure by using in double the vernier of a permeance wave and the vernier of a primary magnetomotive force. CONSTITUTION:A stator 1 has Ns piece of inductor teeth and a rotor 2 has Nr pieces of inductor teeth. When the number of the phases and the number of paired poles of the stator primary winding 4 are respectively represented by m1, p1, those of a stator secondary winding 5 are by m2, p2, and Ns, Nr, m1, p1, m2, p2 are positive integer numbers, the first vernier of the difference between Ns and Nr and the second vernier p1-(Ns-Nr) of the difference between the first vernier and p1 are led out. When the primary winding 1 is excited by AC, a revolving magnetic field is generated in the stator 1, and an electric angle of a rotational shaft 3 can be detected by the output of the winding 5.
