ELECTRICAL & MOTOR CONTROLS TRAINING: INTRODUCTION TO MOTOR CONTROL OPERATIONS AND PROTECTION
In this program, you will learn about the operation of contactors and how these devices are used to control motor operations. This program will present you with the wiring and connection methods used with contactors and motor starters along with their wiring diagrams.

Also covered are the important topic of ARC suppression and protection. You will also be presented with the different types of motor starters, which include full-voltage, combination, reversing, two-speed, and reduced-voltage which are commonly used in motor control applications. You will also learn about plugging speed switches, also known as zero-speed switches, and how these devices are used in circuits to stop motors.

You will also learn about protective switches including fuses, circuit breakers, and motor overload heaters, as well as their respective overload contacts. Methods of troubleshooting these components are also covered.

Fuse curves are presented to solidify the understanding of fuse operation and protection and how to select the proper fuse. Also covered is the effect of ambient temperature on thermal overloads and how they can affect motor control protection.

You will learn how to create safe motor circuits to control the speed and direction of motors. You will be presented with motor control wiring diagrams and their relationship with the ladder control diagram. You will also learn about how two-wire and three-wire control circuits operate, review what makes motors fail, and learn how to prevent potential motor failure.
