Motors and variable speed drives | energy.gov
Speed control allows motors to be oversized to meet extreme requirements without wasting energy during low demand. Pumps and fans typically have variable torque loads subject to the ''cube law'', meaning that reducing motor speed by 20% can reduce power required by 50%. Constant torque loads occur where torque is independent of speed.
