Abstract
A detector for detecting rotor position of a brushless generator having a motive power shaft, a permanent magnet generator (PMG) having a set of armature phase windings and a main generator portion having a set of armature phase windings includes a circuit coupled to the armature phase windings of the PMG 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 in accordance with a parameter of power delivered to one of the main generator portion armature phase windings.
