  • Control Of Motors That Do Not Use Commutators (AREA)

Abstract

PURPOSE: To reduce the current loaded on thyristors to thereby prevent the centrallization of current to a specific thyristor by measuring the stopping and lower speed running of a motor and restricting the armature current to less than the rated current level.
