Abstract
A crystal-controlled cordless universal motor has been developed to be compatible with the Nagra tape recorder, and to streamline camera equipment. A temperature-compensated crystal or tuning fork is used as a stable oscillator. The motor uses a highly efficient dc motor which operates in phase lock reference with a crystal source. Total system efficiency runs as high as 70%. The camera drive provides increased flexibility of movement of the camera. The absence of drive gearing, the use of sealed permanently lubricated bearings and all solid-state circuitry make this motor an extremely reliable, long-life device.
