Match the torque or power of a drive to the process requirements

Improve the working environment
Lower noise levels, for example from fans and pumps
Reduce mechanical stress on machines to extend their lifetime
Shave peak consumption to avoid peak-demand prices and reduce the motor size required
In addition, today’s drives integrate networking and diagnostic capabilities to better control performance and
increase productivity. So, energy savings, intelligent motor control and reduction of peak-current drawn are three
great reasons to choose a VFD as the controller in every motor-driven system.

The most common uses of a VFD are for control of fans, pumps and compressors, and these applications account
for 75% of all drives operating globally.
Soft starters and across-the-line contactors are other, less sophisticated types of motor controllers. A soft starter
is a solid-state device and provides a gentle ramp-up to full speed during startup of an electric motor.
An across-the-line contactor is a type of motor controller that applies the full line voltage to an electric motor.
