Study Guide

Objectives

In this course, students will become familiar with the operation, control methods, sizing, and protection of the most common electric motors used in building services engineering. Upon completing this course, students will be able to:

• Perform the sizing of commonly used electric motor drives in building services engineering and understand their applications.
• Size and select both direct and variable-speed motor drives for specific applications.
• Describe the key components of power electronics, their operation, and their impact on the electrical grid.
• Perform the control circuitry for variable-speed electric motor drives and control systems.
• Explore the possibilities of frequency converter drives.
• Describe opportunities for system integration.
