Seminar Location: Seminar is held at Joliet Junior College’s Main Campus, Room T-1051, 1215 Houbolt Road, Joliet, Illinois.

Seminar Description: This seminar is for maintenance personnel who work with (or around) electric motors. Standard motors and typical motor control circuits are covered. Hands-on exercises allow you to build and troubleshoot circuits using standard industrial components.

You will learn

1. The different types of single-phase, three-phase and DC motors and how to connect and troubleshoot them.
2. How to understand and apply motor nameplate information.
3. How to connect and troubleshoot common motor control circuits.
4. How to connect and troubleshoot control transformers, fused disconnects and other common components.
5. How to connect and apply timers to motor control circuits.
6. How to connect motors using forwarding and reversing circuits.
7. How to connect multi-speed motors using speed control circuits and variable frequency drives.
8. How to select and protect motors and motor control circuits.

Who will benefit

• Electrical maintenance personnel needing to upgrade
• Mechanical maintenance personnel needing to cross-train
• Electricians
• Industrial operators wanting to know more information about the machinery they operate
• Supervisors and managers responsible for maintenance personnel
