Abstract

PURPOSE:To enable to supply an electric power and a control signal to a rotary body through single magnetic coupling means by a method wherein the control signal is duplicated on the electric power to be supplied in the rotary body through the magnetic coupling means. CONSTITUTION:The stationary side of the magnetic coupler 11 like rotary transformer, etc., is connected to the output side of an oscillation circuit 12 for the electric power, and the oscillation circuit 12 is fed from a DC power source to generate AC outputs of sinusoidal wave, square wave, etc. The oscillation circuit 12 is constituted of a voltage controlled type circuit to change oscillation frequency in accordance with an input from the outside, a circuit to generate oscillation synchronizing with an AC input from the outside, etc. The control signal is applied to a terminal 13 in the form of a series of pulse or a DC voltage in accordance with an intention of control to change oscillating frequency or amplitude of the output of the oscillation circuit 12 through a modulator 14. Accordingly the output of the oscillation circuit becomes a modulated signal wherein the AC power is overlapped with the control signal, and is fed to an electric circuit in the rotary body by the rotary transformer 11.
