CONTROL OF ELECTRICAL MACHINES Study Material, Diploma Study Material ,INTRODUCTION TO PLC given Below:
RATIONALE
Various control operations are to be performed on the electrical machines to suit the industrial requirements. Technician is mainly employed to look after the control panels. To make our students employable, they have to be trained in using various control components and circuits. This subject fulfils that requirement.
OBJECTIVES
To understand Electrical control circuit elements including various types of industrial switches, relays, timers, solenoids, contactors and interlocking arrangement. AC motor control circuits for acceleration control, speed control, direction control, braking control and jogging using contactors. Different control circuits for industrial applications. Basics of programmable logic controller. PLC Programming.
