According to the U.S. Department of Energy, motor-driven equipment accounts for 64 percent of
the electricity consumed by U.S. industry. Incorporating energy efficient motors and variable
frequency drives (VFDs) into your facility is a great way to reduce energy costs and boost your
bottom line.
The National Electrical Manufacturers Association (NEMA) has developed a premium motors
program, designed to save energy and money. By incorporating these energy efficient electric
motors you can:
- Reduce operating costs - NEMA Premium® motors reduce electrical demand over standard motors by up to 18 percent.
- Increase reliability - NEMA Premium motors often carry longer warranties than other motors.
- Increase productivity - energy efficient motors generate less heat than standard motors, reducing downtime and maintenance costs.
Variable frequency drives (VFDs) control the rotational speed of an alternating current
(AC) electric motor by controlling the frequency of the electrical power supply to the motor.
VFDs offer many benefits to your electric motors, including:
- Reduced operating costs - VFDs offer greater control over the speed of
AC motors, enabling the removal of throttling devices, valves and dampers, all of which can waste energy.
- Increased reliability - by regulating speed, VFDs prolong the life
and reduce the maintenance costs of motors, driven equipment and switch gears.
- Increased productivity - VFDs give users a finer degree of control,
resulting in more precise process operations and improved product quality.
