<p>The variable reluctance type angle detector is such that for the purpose of providing a variable reluctance type angle detector that is light in weight and low in cost and makes it possible to eliminate harmonics and to improve accuracy and makes mechanical winding possible, and in order to achieve this purpose, the angle detector has an exciting winding (4) and n-phase output windings (6, 7) in the slots (2) of a stator (1), and a rotor (5) disposed for rotation relative to the stator (1), having a shape such that the permeance of the gap between the rotor and the stator (1) changes in a sinusoidal manner relative to an angle (υ)?), and having only magnetic members and no winding, wherein the number of poles of the exciting winding (4) is 1/2 of the number of magnetic poles (3) and the output windings (6, 7) are wound such that the distribution of the induced voltage generated in the output windings (6, 7) corresponding to one phase of the n-phase output windings (6, 7) is a sinewave distribution.</p> |
