Motor & Drive Recommendation/Confirmation

[dan_jenson]

I'm looking for a motor around 3hp for my 2x72 grinder and looking for a drive controller as well. I've picked a Leeson & AC Tech combo with some help from a friend. Can anyone confirm that I have picked a good motor and drive?

Go with a kbac 27d VFD

If you go with that drive, make sure you order the drive in 220/240VAC single phase input and 240 three phase output.

The drive unit shown is not NEMA4, so you will have to mount it in a dust free space and operate it with the NEMA4 remote pad option.

A KBAC 27D in NEMA4 will be a better choice.

I don't see the 119418 on that chart, but it is a 3450RPM motor. I prefer a 1750 RPM unit. The VFD will run it at 120Hz, so it doesn't need the speed, and you most use the VFD to lower speed, anyway.

I wouldn't use AC Tech's SCM series drives as they are scheduled to be obsoleted on April next year. You'll run into some trouble if you were to need parts/support in the future. I would take a look at their SMVector series.

I believe the following drive would fit your application. It can take either single or three phase input.

Get the KBAC. You won't be sorry. I wouldn't bother with 3hp just because you need the bigger (more expensive) VFD. You can get a 2hp Leeson and a KBAC27D for much less.

Good catch count I didn't even look at the motor just saw the actech VFD figured I'd give him some advice on a bit better one
