It is estimated that 38.4% of the total U.S. electrical energy consumption is used to run motors.1 

Annually, 45 billion kWh are used by 1-10 horsepower motors, alone. Even a small increase in 

motor efficiency could greatly reduce energy consumption. Software Motor Company (SMC) has 

developed a patented High Rotor-Pole Switched Reluctance Motor (HRSRM) system that can 

achieve up to 95% peak motor efficiency and maintain similarly high levels of performance over a 

wide range of operating speeds. From the beginning, SMC has focused on retrofit applications for 

heating, ventilating, and air-conditioning (HVAC) systems including commercial rooftop units 

(RTUs). Its 1-10 horsepower product line is well-positioned to replace most commercial RTU 

supply fan motors.
