Abstract
A detector for detecting rotor position of a brushless generator includes a shaft pulse encoder which develops a cycle pulse once per revolution of a motive power shaft and a circuit coupled to armature phase windings of a permanent magnet generator of the brushless generator for deriving a number of interval pulses per revolution of the motive power shaft. A circuit measures time periods between adjacent interval pulses and the measured time periods are converted into an indication of the angular position of the motive power shaft.
