PURPOSE:To operate master and slave rotors at the same speed or at the prescribed speed ratio without mechanical coupling by applying the rotating difference of the two rotors to the rotating speed of the master rotor to control the slave rotor. CONSTITUTION:The output of a pulse generator 2 of a main rotor 1 is applied through an F/V converter 7 and an adder 8 to a controller 5 to control a slave rotor 3. A deviation counter 9, when receiving a pulse generated from the generator 2 and a pulse generated from a pulse generator 4, applies the difference to a D/A converter 10, which converts it to a voltage corresponding to the difference of the number of the pulses and applies it to the adder 8. Thus, the slave rotor is always rotated at the same speed as the master rotor or at the same rotary angle as the master rotor, and stopped at the same angle in case of stopping. |
