Camera Drive Power

Frederick G. Albin

Transistorized recorders have greatly reduced the requirements of camera drive power. A highly frequency-stable portable source of power has been developed. Batteries provide the power to drive a rotary inverter equipped with a centrifugal governor and a transistorized high-speed switching-type regulator. Output frequency is constant at 60 cps ±${1\over2}$ cps. Adequate power to drive cameras under adverse conditions can be relied upon. Prior to describing the system, current motor types and power sources are reviewed.
