Inline duct fans [Fans, Pumps, Compressors]  Merits of inverter drives When you don't need 100% air-flow, you can decrease motor speed of 'Inline duct fans'. In this case, it will save a lot of energy. In generally, Airflow: proportional to motor rotation Load torque: proportional to the second power of motor rotation Energy: proportional to the third power of motor rotation ex. Motor rotation is changing 1500min-1 to 1350min-1 (-10%). Airflow: 90% Load torque: 81% Necessary power: 72.9% Actual necessary power: 72.9% / [inverter efficiency(95%)] = 77%. Constant torque and variable torque characteristics What is your impression of this page?
