Abstract
An angular position signal generator includes a rotor and a stator each having an arrangement of salient magnetic poles. The poles on the rotor are all of the same polarity and are spaced at unequal angles around the axis of the rotor. The poles on the stator are identically arranged so that in at least one position of the rotor all the poles are aligned and in at least two other positions only some of the poles are aligned. As the rotor rotates, therefore, the flux flowing between the poles fluctuates and a winding in the flux path produces pulses of different magnitudes at these various positions of the rotor.
