Motor Starter Circuits Motor Control


Should have a basic degree or knowledge in Electrical Engineering – B tech, B.E., Diploma or any similar relevant educational background
Basic of Schematics, Basic DOL circuit
You can take our Electrical Schematics – Industrial Control course – to understand the basics


Motor Starter Circuits (Motor Controls) is an intermediate course to learn schematics or electrical drawing (power and control circuits) for Motor Starters. We have covered various concepts that are required to design schematics. Before you start this course make sure your basics on Electrical Schematics is clear. You can also take our Electrical Schematics (Industrial Controls) course for learning basics. We are also thrilled to share that this course has earned the high ranking of 9.4/10 by CourseMarks and ranks in the TOP 4% of 94,680 courses!Some of the topics that you will come across in this course are:1) Basic details on schematics – What is schematic ? Where is it used ? Why is it needed?2) Reading & Understanding Schematic – Title block, Disclaimer, Template, Designations, Cross-referencing, Legends etc.3) Symbols & Switchgears – Electrical Symbols along with definition & images. Key technical details about switchgear like circuit breakers,      Contactors Isolators, Meters , Indicators & Protection devices          a) Learn Off load & On Load devices          b) Difference between isolators & circuit breakers          c) NO & NC contacts          d) Power & Auxiliary Contactor – contact numbering, advantages & limitations etc.          e) Instrument Transformers          f) Protection Devices4) Designing circuit – in a step by step method – DOL Motor Starter Circuit Control of motors – Star / Stop, TripHold-on ContactIndication circuitsLocal remote Auto manual operations 5) Basics of electrical interlocking6) Basics of Metering Circuits7) Application in Switchboards and practice questions.
