I have the opportunity to pick up this stout grinder local for $100. I want to run it with a vfd. Here’s the catch. I don’t want to spend a lot on the vfd. It’s a 1/3 hp motor. Can anyone recommend a cheap vfd to power it?
Might look at the Teco L510, inexpensive ($125) and available with either 120V or 230V single phase input. They are easy to setup, I would go with the 1 Hp model, you can use it on other equipment at a later point. You will need a sealed enclosure, I recommend steel to dissipate the heat. Many people use the KBDA-24D on grinders which are sealed and fanless, but 2X the price of the Teco. https://dealerselectric.com/L510-101-H1-N.asp https://dealerselectric.com/L510-201-H1-N.asp
