ABSTRACT:
A pair of polyphase electrical machines with interconnected rotor windings are mechanically coupled together and driven by a rotating shaft. One stator winding is excited by a fixed carrier frequency, and the output frequency at the other stator winding is proportional to shaft speed. The output signal frequency is not zero at zero shaft speed and is unique for both directions of shaft speed. Brushes, slip rings, and electrical connections to the rotating shaft are not required.
