Use variable speed workouts

Electric drives are an essential component in industry. Electric motors are used everywhere (pumping, conveying, ventilation, etc.).

The International Energy Agency (IEA) estimates that 70% of industrial electricity consumption is used to power equipment. Reducing operating costs therefore requires the use of energy-efficient drive systems.

Most applications use fixed-speed motors. Using a variable-frequency drive (VFD) to control a fan or pump is a more efficient way to regulate flow than using simple control valves or inlet or outlet dampers.

For a motor operating under variable load, speed control is a key factor in achieving energy savings, given that 95% of operating expenses are energy costs.

Variable frequency control adjusts the frequency of the power supply, which affects both the motor's speed and torque (or power consumption), allowing the output power to be tailored to actual demand rather than maximum demand.

This document is intended to help identify the benefits of this technical solution, assess the expected energy savings, and apply regulatory and standard requirements.
