Discover how Yaskawa AC Adjustable Frequency Drives (AFDs) improve pumps, fans, conveyors, compressors, and industrial machinery through energy savings, precise motor control, and advanced automation integration.
Yaskawa AFDs: Industrial Applications Across Pumps, Fans, Conveyors, Compressors, Machine Tools, and More
Yaskawa AC Adjustable Frequency Drives (AFDs), commonly known as Variable Frequency Drives (VFDs), are among the most widely deployed motor control technologies in modern industry. From water treatment plants and HVAC systems to conveyors, compressors, machine tools, and packaging lines, Yaskawa drives improve process control, reduce energy consumption, and extend equipment life.
Industrial facilities often discover that motors account for more than half of total electrical energy use. Applying Yaskawa AFDs to variable torque and constant torque applications allows operators to match motor speed precisely to process requirements instead of running equipment at full speed continuously.
This guide explains how Yaskawa AFDs operate across major industrial applications, highlights selection criteria, and outlines the benefits that make them a preferred solution for pumps, fans, conveyors, and industrial machinery.
What Are Yaskawa AC Adjustable Frequency Drives (AFDs)?
Yaskawa is a global leader in motion control and drive technology. Its AFD product families—including GA800, GA500, A1000, P1000, U1000, and specialized industrial drives—provide precise motor speed and torque control across numerous applications.
An AC Adjustable Frequency Drive controls:
Motor speed
Torque output
Acceleration and deceleration
Energy consumption
Process stability
The drive converts fixed-frequency AC power into variable-frequency output power, allowing the motor to operate exactly at the required speed.
For example:
A pump requiring only 70% flow can run at 70% speed.
A ventilation fan can adjust airflow dynamically.
A conveyor can synchronize with production demand.
A mixer can maintain precise process consistency.
This flexibility significantly improves efficiency and operational reliability.

Precise flow control improves operational efficiency while reducing equipment wear.
Pump Affinity Laws
Pump power varies with speed according to affinity laws:
Flow ∝ Speed
Pressure ∝ Speed²
Power ∝ Speed³
A 20% speed reduction can lower power consumption by nearly 50%.
This explains why AFDs often deliver rapid return on investment.
Yaskawa AFD Applications for Fans
Fans are another ideal application because airflow requirements frequently change.
Instead of using dampers to restrict flow, Yaskawa drives adjust fan speed directly.
Typical Fan Applications

Fan power follows cube law relationships.
Reducing fan speed:
100% speed = 100% power
90% speed = 73% power
80% speed = 51% power
70% speed = 34% power
The savings are substantial.
