Abstract

PURPOSE: In the variable frequency control system of an AC electric motor by pulse commands, the response quantities of speed or hunting and so forth are detected to be used in feedback pulse, and the pulse is added to command pulse input points like a digital to responsively control a feed phase, improving the movable-character in low speed range.
