ABB - Energy efficiency. A solution

Intelligent motor control methods -- variable speed drives -- can help in solving the energy challenges we all face. Variable speed drives regulate the speed of a motor and can reduce energy consumption by as much as 30% to 50% in many applications and in extreme cases by as much as by 90%. Pumps are one of the most common motor applications and offer the biggest potential for saving energy because at half the speed only one-eighth of the power is needed.
