Electrical Accuracy of Selsyn Generator-Control Transformer System
Harold Chestnut · Transactions of the American Institute of Electrical Engineers · 1946
THE military requirements for high accuracy position control systems have placed emphasis on the need for a voltage signal source which can indicate electrically a mechanical shaft position. In addition this signal source must have high accuracy, marked dependability, and the capability of continuous mechanical rotation. A modification of the conventional Selsyn generator-motor system1 has been developed and used extensively to fill this need.
