Electric Motor Controls
Electrical
Course Number: EMC-302
Course Description:
For those employed in the industrial and manufacturing sectors, understanding electrical motor controls is a valuable skill for electricians, production managers, technicians, designers and even line workers. This course is a comprehensive introduction to motor controls, covering the essential topics for employees working in a variety of industrial and production settings. Attendees will under-stand, follow and troubleshoot motor control circuits and understand how components work to determine if they are bad. This will drastically reduce down time by only changing the bad parts and teach the technician to quickly and accurately diagnose and repair problems. Theclass uses plug and play components built into shippable cases that allow progressive education during the hand on portions or the training. This course can easily be transported to your place of employment as well at our hands-on training center.
​
Each student will receive class books, work activity sheets, self-test progress evaluations, as well as questions from the instructor to make sure they understand the material presented. It is expected that an attendee will leave the class with the basic knowledge of the subject and possess new found skills to better equip them when they return to their job. A certificate suitable for framing will be issued to each attendee who successfully completes the course.
