Abstract:
A motion control drive system for producing and controlling programmed and remote controlled machine operations by directing and controlling the performance of a rotating output shaft. The output shaft is then used to provide drive power and programmed control of various machine operations required to be controlled by a program of predetermined machine operating commands. The final program of operating commands being stored on audio magnetic sound recording tape or other audio recording media for purposes of storage and subsequent use in directing and controlling a given machine. The program of operating commands being stored on two track audio magnetic tape in the form of dual, first and second, time varying and or fixed frequency audio signals whose frequencies interact and become the function of the commands to be executed. The dual audio signals then being amplified and used to control a pair of high frequency, alternating current, gear head synchronous motors coupled through a differential gear train to the system output shaft such that the direction and velocity of the system output shaft can be infinitely controlled from zero to maximum speed in either direction of rotation. A general purpose digital computer being used to develop and store the machine control commands in digital form.
