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