Need help with Bandsaw Motor Swap- Dake V16

Hi everyone. I am looking at buying a Dake V16 Bandsaw and was hoping to do a simple motor swap to take it from 3 to 1phase, since there is a hydraulic speed change and I don't love using VFD controls in place of the original on/off. I am not too worried about loosing access to blade welder/grinder. Unfortunately, the motor plate is not the standard Nema Plate. Can anyone decipher this plate and let me know if this is a plug and play situation? Thank you in advance.

The motor plate on the Dake V16 isn’t NEMA standard, which likely means it’s a metric frame (common on import motors). That usually rules out a direct plug-and-play swap with a standard NEMA motor. You’ll likely need an adapter plate or some custom mounting work. Also, double-check the shaft diameter and height. Those can differ too. That said, swapping to a single-phase motor is definitely doable, just not 100% drop-in.

Just keep the 3ph motor and use the vfd in a fixed mode or a rotary phase converter

Or, route the original bandsaw controls to the VFD's inputs.

If it is just run/stop then that wouldn't be a particularly onerous job.

If the OP was willing to do a bit more, they might even be able to have the grinder/welder working (assuming the grinder is driven by the same motor as the saw pulleys).

They are not, and never would be, since you need to weld and grind when the wheels are off. Mostly the welder allows inside cuts, cut the blade, put it through the hole , weld , grind, remount, then cut the piece.

But going 3ph would still allow them to use the grinder if it's 3ph wired into the bandsaw and not a sep. plug.
 
Thank you everyone for. your feedback. I was trying to avoid wiring a VFD to the original controls but it sounds like its not impossible. I have VFDs on my belt grinder and mill but they are all externally controlled. I feel confident that I could fab a mount for a NEMA motor but the metric shaft diameter sounds like the real hassle.

Re: welder. I never thought about that purpose (interior cuts) which is really neat. Maybe if I had that resource I would use it, but as of now, I have never had the need.

So there are two motors then, one for the grinder and one for the bandsaw pulleys?

If so wouldn't the grinder's motor have to have the same characteristics as the one driving the bandsaw, to be powered by the same VFD?

usually that would be the case. Unless it was treated as an attached unit, or wired into a separate outlet. In a fixed setting situation where the VFD is only providing 3ph conversion at frequency I don't think there would be a problem. BUT usually VFD's don't like switches downstream.
so you could not just turn the saw on, shut it then use the grinder or welder. It may be possible with a more complex setup.
for a rotary phase converter, no problem.
