A detector for detecting rotor position of a brushless generator having a motive power shaft and a main generator portion having a set of armature phase windings capable of receiving AC power and developing a back EMF voltage during operation in a starting mode, includes a circuit coupled to the set of armature phase windings and capable of responding to the AC power for producing a back EMF estimate signal representing an estimate of the back EMF voltage. The detector also includes a circuit for converting the back EMF estimate signal into an indication of the angular position of the motive power shaft.
