Abstract
IN SERVOMECHANISMS used in military applications, one of the weakest links is the electronic amplifier. The electronic amplifier is undesirable primarily because of its fragility, maintenance requirements, low power efficiency, and often objectionable warm-up time. The magnetic amplifier is much more rugged, has a much longer life, has a greater power efficiency, requires much less maintenance, and has no warm-up time. Thus, one of the most obvious and potentially fruitful applications of magnetic amplifiers is in the control of 2-phase motors in servomechanisms.
