Title: Lab 1-3: Introduction to Motor Starters (Motor Controls)
Course: Troubleshooting Labs > Section: Final Troubleshooting Labs

INTRODUCTION

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.
