Every time you hear a factory machine start up, a motor starter is quietly making sure the motor powers on safely and reliably. Unlike the simple push-button circuits you’ve already built, motors draw large amounts of current that require special protection. That’s where starters come in—they combine control and protection in one device. In this lesson, you’ll learn how motor starters work and how to wire them into control circuits.
Watch the following videos to learn how to troubleshoot the new components you will be using in this lab. You will be able to reference these videos in future labs.

On a Motor Controls trainer, build and demonstrate the circuit shown in the ladder diagram above.
When a user presses a Button, the Motor Coil energizes.
Submit a video in which you describe and demonstrate the operation of the circuit.
Videos should be 30 seconds or less. For identification purposes, show your face at some point in the video. If you are working with another student, each of you must record and submit your own video.
