Precision Speed Control
A precision speed control is capable of maintaining motor speed within 1 part in 25,000 under voltage variations of plus or minus 20 per cent and load variations from zero to full load. For motion picture production this order of regulation provides the equivalent of synchronous operation without physical connection between such motors.
