ANALYSIS OF A THYRISTOR-CONTROLLED D. C. SERIES MOTOR

Abstract

The operation of a thyritor controlled do series motor fed fron a single phase ae supply his been investited. A }a1f controlled convertor with freewheeling diode, tnd associated control circuit, have been designed, fabric.'atcd and tted With the pulsed supply vole to the rrature circuit and assaming linear magnetic circuit, expresslon for armature current bias 'been deduced using l transform tethod, From tHs expression for arnature current, epresior3 for avorage nd rins values of aztture current, torque devLoped, r8 value of line current, input power factor, dilcerer4t and distortion 11~cjt.,Irs hvc beer, obtIned. ii. cOm91On between eerientl 4nd thcoret1c1 results has been tade.
