DC Motor Control through Converters

DC Motor Control through Converters: DC motor control is conveniently and efficiently achieved by phase-controlled converters wherein the ac input voltage is converted to a controlled dc output. The commutation process, the transfer of currentĀ from one thyristor to the other, in these converters is the inexpensive natural or line commutation. As, an incoming thyristor is […]

Single Phase Induction Motors

Single Phase Induction Motors: A Single Phase Induction Motors comprises a single-phase distributed winding on the stator and normal squirrel-cage rotor as shown schematically in Fig. 10.1 wherein for convenience the stator winding is shown in concentrated form. There are two important methods of analyzing this motor, viz. cross-field theory and rotating field theory. As […]
