That may be what he does. The lift motor is turning max spd but with a slow enough rpm out of the rgb, and enough practice,is able to dial in on his next cut accurately.

If that is the case, then i need a 10 vfd since im starting off with a 10hp motor and was going to upgrade to a 20hp in the future if the need of more hp was required. The guy i bought my mill plans off of only uses 1 vfd for both his 10hp and 3/4hp motor. I have no idea how he controls each...

That is a piss poor shame its cheaper to fly people in than hiring locals. My coworker is an aviation electrician/avionics tech but he know his chit on the avn elec side. Our acft has 3 220v ac 3 phase 400hz generators and a transformer rectifier for 24v dc. Minus the hz, its very close to the...

From that info @Guyfang i think i’ll build me a gen set with my mechanical 4bt turbo cummins and buy a new gen head that already has the recommended voltage regulator @87cr250r mentioned, built in to the new stamford head. If i can get an electrician to come out and take my money (hard to...

I don't know the difference between them. you have any input?

Oh yea, the power company will bring it out, for a 6’ tall solid gold monkey. Seriously though, no, not for 1 customer, even though there is 3 phase 4 miles to my west and high tension/voltage and sub station to my south. Bringing me 3ph also ties my hands to where i have to set my mill up...

gotcha. replying to one post can get intermingled all to easy. but i am NOT eliminating any VFDs, and I'm guessing he was replying to your post of eliminating the VFDs and direct wiring the motors, which I will not or can not do. from my initial post, i stated using VFDs with a 3 phase generator...

@87cr250r So the DOL is null since my plans are to use 3ph and VFDs, correct? I did find a 3ph power controller up to 24kw, regulating voltage. Is this what you are referring to as a voltage regulator? https://www.ato.com/4-wires-scr-power-controller A commercial sparky was suppose to have...

total watt draw with all 3 motors (15hp, 5hp and 1.5hp if i go with the 1.5) is around 14kW. Im not sure what DOL means, but i think it means direct operating load, correct? if so, i am not finding anything on any of the websites for any of the motors I'm looking at for potential purchase for a...

From what iv researched on band/blade spd, there is an allowable varying fpm band speed. Smaller cut width mills use single or three motors. The mill im waiting 11 months to take delivery of (lt 15 wide) has a 36” cut width and motor choices are 10hp 220v single phase, 220v 3 phase or 460v 3...

how would starting the 1.5hp (or 3/4 hp haven't decided yet) running through a 10:1 rgb to only lift/lower the sawhead help supply power to help start the larger motor? I also do NOT want the lift motor running full steam ahead, NOR do i want my main motor running full steam during initial start...

@Evvy iv only come across 1 15hp motor that is more likely to actually be single phase. https://www.mscdirect.com/product/details/89372825 $8,000, I'm sure it would SUCK the amps, vs. a 3ph, but no listing on amp draw. the other 15hp motor is confusing bc it says 3ph in the title, but 1ph in...

Happy or not, there isnt a 15hp 1ph and options are greater in the 3ph range. Edit: What does post 2 have to do with anything? If its how my “shop” is wired. Already answered.

@Evvy Please read post #1 and post #3 I dont know where you got i have or looking at getting a 15k.

Huh? im not understanding what you are saying.

Its a build in progress iv been working on for 3.5 yrs. I can either do a design change and spend a bit more $$$, or throw money at r&d and hope it works long term or throwing more $$$ at building it as the plans called for. Plus iv got 1000s of lbs of pecan logs i need to mill or pay half the...

Iv got drive shaft lord mount isolators off our helicopter that get replaced for the smallest of cracks yet are still very much in good shape. My plan is to put the ignition/gauge panel from the gen cart the eng came off of, back on and use 4 mounts top and bottom to absorb the vibes.

Before i would ever consider dropping that much $$$ i wanna now how reliable these thing are. But that is also way more than i want to spend right now. But thanks for the link.

Iv got a 4bt cummins rated at 100hp @2000 rpm for a power plant, and that wont change. As for the gen head im looking at, it is a stamford. I am wanting the KISS method of building my own generator if no one has any input regarding the 30k generators, let alone positive input for reliability.

What is the amp rating on that switch? Im sure its more than 60 amps. If so, great, that’ll allow me to feed into a pdp. Each motor has a different amp draw, requiring 3 different breakers. If i want to add later, as long as the main switch is large enough.
