What does a variable frequency drive do?

A VFD matches motor speed and torque to the process demand. The result can be smoother control, lower mechanical stress and reduced energy use—especially in variable-torque applications such as pumps and fans.

Match motor output to the process

Instead of running a motor at full speed and restricting the process mechanically, a VFD regulates frequency and voltage to deliver the speed and torque the application actually needs.

Why pumps and fans can save energy

In variable-torque loads, a modest reduction in motor speed can produce a much larger reduction in power demand, while soft starting also reduces mechanical and electrical stress.
