  • Why You should take this seminar

    Participants learn the basics of electric motors including how to maintain and troubleshoot common problems found in the workplace. This course covers the operation and maintenance of AC and DC motors, including 3-phase, dual voltage and multiple speed motors. For each motor application, factors such as driven load, environmental conditions, power availability and performance capabilities will help determine what type of motor is the best fit for a given purpose.

    Participants will become familiar with the National Electrical Code® (NEC) requirements for motor operation and installation. Course content progresses logically from basic operational theory to the actual operation of various types of AC and DC motors. The training includes numerous hands-on lab exercises designed to help participants operate, test and troubleshoot electric motors.
