A typical manufacturing environment utilizes electrical motors of one type or another. Many of these motors are high-voltage, 3-phase motors that are controlled using a magnetic motor starter. These motor starters are essentially electrically operated switches that also provide overload protection for the motor.
In this module, you will learn about motor starters and contact relays, and how they are used to control the operation of a motor. You will take what you have learned about logic functions in Module 2 to design and wire various circuits that control a motor starter.
