Mr. Rakesh, Pl explain how many % of external resistance need to cut en each step during operation of slip sing motor? also pl explain on which bases u considered 1.4, 0.35, 0.15 & .08 value for calculation of step wise resistance.
cutting of resistance should be on application of motor where to we are going to use & lifting load capacity. Also its depend on which type of resistance we are using -- SS punch plate grid / punch wire grid/ oil merge/ liquid water resistance.
