Opportunities for Downsizing Motors

This report is a technical document prepared by Bolder Energy Engineers for Turntide Technology, focusing on the opportunities for downsizing motors in HVAC systems. It outlines the findings of a study that indicates many motors operate below their rated load, leading to inefficiencies. The report discusses the benefits of downsizing motors, such as energy savings and reduced capital costs, and provides criteria for evaluating whether a motor can be downsized. It also includes a methodology for measuring the power draw of baseline motors to determine the appropriate size for replacement motors. The report references industry research, including guidelines from the U.S. Department of Energy, and presents case studies demonstrating successful applications of motor downsizing. The document emphasizes the importance of assessing specific site conditions to ensure effective motor sizing and energy efficiency improvements.
