Abstract
PURPOSE: Each phase voltage of the primary winding of two units of wound-rotor type machines whose rotor is mechanically connected and whose secondary winding is electrically connected is multiplied and added, and from the difference in their output the brushless detection of the adder signal corresponding to the revolving angle of a synchronous motor coplied with rotary machines is made possible.
