As reported previously by the authors, A. C. excited C-shaped electric sheet steel with a movable coil placed between the poles can be made as a directional positioning unit. Further developement has been made to facilitate it as an automatic positioning controller by adding another winding to the cone, the induced constant voltage lagging 180° in phase behind that in the moving coil. With a mechanism to keep up the resultant voltage to zero, a simple automatic positioning controller is made.
A three channel electronic switch has been devised for simultaneous observation of the wave forms of excited voltages in the moving coil and the added winding and their resultant voltage.
