New to me jointer!

[Jim Riseborough]

What did you end up paying for the jointer. It's always been high on my list of wants.

I got it for $1050. Seemed ok deal, Most Delta DJ20's I saw were over $1200. Does not have helical head though. 3ph too, so i have to get a VFD.

As you may know, HP is lost with a VFD. You can do the calculations, but you may want to consider swapping out the 3P motor for a single phase, unless you want to go the rotary phase converter route (where no HP is lost, if sized correctly).

The VFD I bought is designed for this I believe so I dont loose HP.

Newer VFDs with Sensorless Vector Control (SVC) or Flux Vector Control will allow a motor to produce at or near both rated torque and Hp, even at lower than 100% speed.

Simple (older) VFDs used just V/hz control, and if a motor was run at less than its synchronous speed, it would produce proportionally less than rated Hp. So if you plan to run slow with a old VFD, Jeff is correct.

However, I can't imagine why you would want a jointer or planer to be running at less than its rated speed. If running at 100% speed, even using a old technology VFD, this power loss should be a non-issue. ....You would basically be using the VFD as a soft start only, and presumably for phase conversion in this case.

Im pretty sure I got Flux Capacitor Control - It says fluxmaster on it. https://www.tecowestinghouse.com/pro...ives/fm50.html
