• ### Variable Frequency Drive Efficiency

At 1/4 of its rated operating speed, the fan delivers 25% of its rated airflow, but requires only 1/64 of full load power. Even with the low VFD efficiency of 47%, with adjustable speed operation the power required by the fan and the variable frequency drive is only 0.66 hp. hp 25% = (20 hp x (1/4) 3 / (47/100)) = 0.66 hp.

• ### The efficiency of a machine is the ratio of the work done

Efficiency is the ratio of work output to the work input, where Work output = work done on the load Work input = work done by the effort So, efficiency is the ratio of work done on load by the machine to the work done on the machine by the effort.
