What you'll learn?
- Build a complete ciruit diagram for a DOL (Direct-On-Line) motor starter
- Dimension (size) properly the power components
- Both IEC/NFPA style circuit diagram (symbols)
- 2 common variants of the protection circuit
- Fuse monitoring solution
- Difference between a contactor and a relay
Course Overview
Hi,
this is a course series I started to help various colleagues in the world of electrical engineering and industrial automation to understand and to be able to design and implement a most common motor starter for industrial automation applications - DOL motor starter.
Since this is a first course in the series, I start of not only by building a whole circuit diagram but also explaining in detail all the circuit components, both for power and control circuit.
You'll also learn how to properly dimension (size) all the power circuit components. In the following courses we will more concentrate on the control circuit since after this course you will understand:
- the symbols (IEC/NFPA)
- the power circuit components such as fuse, contactor, motor overload switch aka motor protection circuit breaker (MPCB)
- the control circuit components such as START/STOP pushbuttons, emergency stop pushbutton, signal lamps (aka pilot lights), relay and it's role etc.
Regarding manual controls, that is, pilot devices, I will also publish soon 2 courses (one for Siemens devices and one for Allen Bradley) that will teach you how to efficiently plan those pilot devices such as START/STOP push buttons, emergency stop push button, selector switch (MAN-O-AUTO), twin push button, pilot lights (signal lamps).
So please refer to those respective courses if you want to learn in detail how to configure those devices which tend to get complicated since they normally constitute from many different parts/pieces which if properly configured then form a whole working component.
Hope you will enjoy the course and I'll be seeing you in the lectures.
Stay safe and well.
Best regards,
Ivan Vidovic
