Performance Evaluation of Software-Controlled Switched Reluctance Motors
The Western Cooling Efficiency Center (WCEC) and National Renewable Energy Laboratory (NREL) evaluated the potential of an emerging technology — a high rotor pole switched reluctance motor (SRM) driven by a software-controlled inverter. WCEC conducted laboratory and field testing to measure the performance of the SRM system used to control the indoor blower of a packaged rooftop unit and compared the performance to: 1) an induction motor controlled with variable frequency drive and 2) a fixed speed induction motor. NREL evaluated the constant and variable speed operation of the SRM system as a retrofit for commercial refrigeration condenser fan motors.
