POWER GENERATING* FLOATING* BRAKING CONTROL IN POWER FAILURE FOR THYRISTOR LINEAR MOTOR

摘要

PURPOSE:To make it possible to hold both floating and breaking forces available at constant levels, by regulating each armature coil current through thyristor phase control to stay at the normal level existing prior to power failure, by means of speed electromotive force in dynamic braking of a thyristor linear motor which is treated as an alternate of the lost armature coil power source.
