Study On The Drive Control System Of Linear Pulse Motor (LPM)

Input pulse signal can be directly transformed into micro-step linear motion by use of linear pulse motor,which have found wide applications in the digital linear servo systems with high positional accuracy and high reliability.Taking SLPMU-025A, a two-phase hybrid LPM manufacturing by SHINKO Motor Company Ltd,as an specimen,the study on the drive control system is carried out in this thesis,which contains:(l)Three kinds of drive circuits are designed and comparison analysis in theory is done;(2)Introduction to AT89C51 microchip as controller and special micro-step constant current driver,a great variety of running modes driver control are developed;(3)Experimental testing and theoretical analysis ofcurrent waveforms and displacement graphs and velocity graphs are carried out in case of different micro-step constant current driver.
