Variable frequency drives (VFDs or inverters) now play an important part in major industry.
Within the last 10 years they have been perfected to control and vary the speed of 3 phase electric motors. They serve many purposes, besides speed control.

Great motor and VFD, June 9, 2017 By Anonymous (Grassflat, PA)(Verified)
Perfect for my belt grinder. Gives infinite speed control easily with no need to change pulleys. Should also work great on lathes and drill presses and many shop tools for the home workshop with only 115 volts available.

Fantastic vfd you can virtually do anything you have to without adding a potentiometer because it has one built in. its simple Easy to use the booklet makes sense and doesn't complicate how to program the vfd from start and stop time and just endless programmability for the price I would recommend this to anyone thinking about getting it. You are getting a great vfd for the price it's a great deal. P.s I'm not an electrician I do have some safety training but it's simple enough that even I can wire it up and use it I'm an aspiring knife maker and saved thousands on building my own 2x72 belt grinder with a vfd
