Written by Robert Amos
Variable Frequency Drives are used extensively in many applications where the speed of a motor is required to be controlled to maintain a specific temperature, pressure, or flow. Cooling towers, chillers, fans, pumps, and multi-motor pumps or fans are some examples of common VFD applications.
This course is designed to introduce HVACR Technicians, and others involved in the HVACR industry, to the Fundamentals of VFD motor control systems. This course will provide students with an understanding of the function of a variable speed motor control system as used in a typical commercial building environment.
