Motor Starter Circuits (Motor Control)

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
