Title: I&I Contract # DE-FG36-02GO12065 Final Report

Abstract

Currently only 5% of residential HVAC systems are sold with variable speed (VS) circulating blower motors in spite of the significant energy savings and comfort benefits associated with variable speed motors. This is due to the very high cost of variable speed motors currently on the market. The project goal is to develop a version of the DynaMotor{trademark} variable speed motor for use in residential HVAC systems. The motor will have performance similar to existing VS motors used in HVAC systems but will sell to HVAC OEM's for 40-50% less than existing VS motors thus bringing energy saving VS motor technology to middle tier HVAC systems. The DynaMotor is a unique, patented variable speed motor/drive technology that has significant advantages over other VS motor/drive technologies including low cost. Prior to this project development was focused exclusively on the factory automation market. The project goals included efficiency, speed range, audible noise, reliability and cost. All goals except cost have been obtained. Cost cannot be finally determined until a manufacturing partner is selected although the cost goals appear to be achievable. Negotiations with two potential manufacturing partners are underway. Although the project technical goals have been achieved, further improvements in audible noise,more » torque ripple and simplicity of controls are being explored. The project is moving from the R&D phase to commercialization. In addition to the previously mentioned negotiations with potential manufacturing partners, approximately ten motors have been supplied to HVAC OEMs for test and evaluation. Reaction has been largely positive. If the cost goals are met it is expected that significant sales of the motor will result thus increasing the utilization of VS motors in residential HVAC and resulting in significant national energy savings.« less
