How much does a VFD cost?

$200 to $500 per horsepower
Typical installed costs of VFD systems range from $200 to $500 per horsepower (HP). Suppliers can assist users in selecting a VFD that is properly sized and that includes any necessary filters and reactors.

Which VFD is best?

In low voltage VFDs, we think the best VFDS on the market are the WEG VFD, the Yaskawa VFD, the Toshiba VFD, the LSIS VFD, and the Teco VFD (especially in the high horsepower low voltage models) All of these are good companies with well designed reliable equipment. We stock both medium voltage and low voltage VFDs.

What size VFD do I need?

Sizing of a VFD is based on the rating of the VFD and the motor load. When the VFD is rated in horsepower (or in horsepower and output current), the VFD must be sized to be greater than or equal to the horsepower rating of the motor (or motors).

Can you oversize a VFD?

An oversized VFD can be used for a smaller HP motor. The advantage of this application is that if the motor requirements increase, the VFD may be large enough to still handle the increased load.

How many types of VFD are there?

There are three major types of VFDs here, all of which convert AC input into DC, followed by changing DC into a variable AC output with the help of an inverter. The three different AC VFDs are Current Source, Voltage Source and Direct Conversion drives.

Who makes ABB VFD?

ABB VFD drives are developed, manufactured and sales by ABB Group, it’s a famous brand VFD. It’s mainly used to control and adjust three phase AC motor’s speed.

Can you use a VFD on any motor?

Summary. While we’ve solved the single-speed problem of AC induction motors by introducing the variable frequency drive, not all motors are VFD compatible. Some motors are specifically designed to run on VFD power, while others need a few components added to the system to be compatible.
