Distracted by my paying job, I haven't yet ordered my VFD. Glad to see this video. I'm hopeful to have my grinder running by summer. Thanks for this tutorial, Brian. I'm annoyingly slow and cautious when it comes to wiring. This has helped me feel confident to move this project to completion...as soon as I get the VFD.

I wired mine off an old video with all 10 gauge wire. This would have been way cheaper. But it also allowed me to run a 30 foot cord without having to ever worry about starving my motor for power and I can roll my machine outside when the weather is nice. Thanks for the updated video. Will probably just use 12 gauge next time.

[@GlennLaguna]

Just FYI. Those Yellow ring terminals are for 12-10 gauge wire, and you are using 14-16 gauge wire. You can buy the correct Blue ring terminals to fit that screw for the ground perfectly. For that 16 gauge 120v whip those Yellow ring terminals would be way too small to crimp correctly. Not that they will have stress on them, but the correct Blue ones fit 14-16. For KBAC or KBDA, the line terminals are #6 screw and the ground is #8 screw for the proper blue(14-16) ring terminals.

Thanks Brian for the information. I’m so glad I ran across your video about this setup. I have the same motor and same vfd , both still in the box. I’m finally ready to put somthing together. What 2 x 72 would you recommend to put with these two units? The best fit I guess I should say. Your instructions were very well spoken and easy to follow! Thanks again!

[@HouseMadeUS]

Happy to help. I am partial to my own setup which is the Revolution 2x72. You would need to build it from our kit or scratch. If that isn't an option I like Ameribrade as a pre built unit. Awesome gear. 🤙🏻

[@HouseMadeUS]

And if you want more info on the Revolution just head over to my website www.HouseMade.us thanks again Buckaroo.

[@edwardlance2379]

Understand that at 120v, 2HP is around 16-17 amps at steady state. Start up amperage is going to be higher, and depending on the exact motor, it could draw up to 200% of operating amperage on start up, so be sure your breaker, wiring, etc is rated appropriately. Exact amperage is going to depend on the motor's efficiency and power factor. Also, as load increases that induction motor is going to suck more amperage. This is why we use 220v in our shops, you can run more powerful motors without drawing lots of amps.

[@christiangrunewald46]

What about adding the reverse function switch? Thanks!

[@irahouseweart1204]

Thanks Brian!

[@HouseMadeUS]

Nice job Brian, the videos get more and more pro! Have you converted your Enco mill drill to 3 phase yet? I'm thinking about that now as it's such a pain to change the belts around for different speeds...

Was just thinking that exact same thing. Belt changes is a terrible design.

[@HouseMadeUS]

That would be a fun project. I'll add it to the list. Thank you Scott.

[@shed_7245]

Excellent description Brian! Any other video only half describes 118v & ignore 220/240. How do I install a reverse switch?? Heard it's stupid simple.. but I don't know how.

[@nuke6702]

It's a good idea to tape up the wire nuts. Keeps them from walking off and shorting to the motor case via any vibration.

[@fredfchopin]

If you aren't planning on re-wiring it ever, I'd just solder the wires together and put some heat shrink over them. A bit more work than a wire nut (and I'll typically start with wire nuts just to confirm everything is working) but once you solder it then you never have to worry about it ever again.

[@nuke6702]

@@fredfchopin Until you have to replace it. Motors don't last forever.

[@fredfchopin]

@@nuke6702 True, but in that case solder a connector on it. There are molex connectors (and plenty of others) that have a latch to keep them together. Easy to replace one side or the other if you ever need to.

[@simondoug]

This video is awesome. I learned a lot. Wiring up my first VFD and this just made the job a ton easier. Thanks a lot.

[@HouseMadeUS]

Thanks Doug! I appreciate that.

[@AZCampcraft]

great video and explanation on the process. I followed along for 110 and when i go to test out the motor and vfd, It engages for a second and then pops the breaker. This is set up in a garage that was a carport and upgraded later on to a garage, And only has one wall outlet out here that was tied into an existing line of the house. Should i just run a new outlet on a new breaker to avoid that problem? Beginner here with not much knowledge any info or tips is appreciated, Thanks!

[@HouseMadeUS]

Is the outlet a GFCI? If it is the VFD will pop the breaker. Replace the outlet with a standard outlet and it will work fine.

[@christopherlund1198]

Why the 50 Amp plug? The 14 gauge wire looks a bit anemic in relation the the plug. I have 220/20 amp outlets in my shop. Only one 50 amp outlet, and my welder already occupies it. Cheers! Nearly have my rev3 finally built. Need to fab the tracking mechanism and wire. And then a tune up.

[@HouseMadeUS]

I like flexibility, so I use 50amp plugs for a lot of things. Definitely not code, but my shop can be reconfigured pretty quick. Glad you're building the Rev! Cheers!!

[@trwhitford65]

Is it possible to convert a 220 single phase motor to 110 and have variable speed? Sorry for the crazy questions. I had a great deal on a 2hp single phase motor.

[@raysimon1368]

Hey Brian I was wondering will that k back 27d vfd be a good choice for my Bridgeport mill with a 2hp 3phase step pulley motor and is there any disadvantages using 110 in to the vfd to 220 thank you very much for your videos electric is my biggest downfall on my projects

[@HouseMadeUS]

It could work. With 110 you lose 1/2 hp.

[@307mtb]

All of my other grinders are single speed and one direction. I don't really have a need for forward and reverse or the speed adjustment could I just use the same iron horse motor but a single phase version and wire it to just a switch instead?

[@HouseMadeUS]

Yes, any single phase motor will work fine. I really enjoy having speed control.

[@roberthelman7838]

I’m having trouble locating a Kbac 27D do you know if the Kbac 24D will also work with the Iron Horse motor that you suggest? Thanks

[@HouseMadeUS]

I do not think it will. It supports 1hp or less.

[@gabrieldenton2020]

Are these all 3 phase motor (t- labeles the same.? I have the Chinese vfd you recommend in another video and a 1.5 hp 3 phase motor.

[@Ihatezidiotz]

Pretty sure KB sells a fwd/rev switch you can add to the unit.. very nice if you're making a buffer, etc

[@HouseMadeUS]

Yes they do. Easy to install too.

[@garyboardwine3349]

I'm sure aware of the reverse, forward switch at the vfd , and also the single or double motor speed in the vfd, to get your preferred rpm if needed

[@HouseMadeUS]

Yes, definitely a good upgrade!

[@Immolate62]

How much actual power is delivered when limited to the 120v source? Does it need 20 amp? Sorry if any of this was asked and answered. I listened to the whole video. I don't think 120 is viable for me as I have a 3HP motor on my Evolution. Is there a KBAC that can convert 220 1 phase to 3 phase sufficient for a 3HP motor? I see ones that are for 380v-480v but don't want to go there.

[@HouseMadeUS]

You do lose a 1/2 HP when you run 110, which is negligible. There isn't a 110 VFD that can power a 3hp (that I know of)

[@michaelprue9024]

Just checked on the vfd, not in stock on Amazon. Will keep checking until available

[@HouseMadeUS]

Sold out for months now.

[@camerongeorge4246]

Can you wire the cheaper vfd that you recommend with 110v?

[@HouseMadeUS]

Unfortunately no.

No 60hz is fine.

I'm thinking about ordering one of your Revolution ultimate bundles and I have a three-horsepower motor that meets all the other specs for this build will that be okay

[@HouseMadeUS]

Yes you will just want to pair it with a VFD that can accommodate 3 hp. The cheaper 220 version I have on my resources page will do it just fine.

We watch your video it was good, but we have a 1 and a half horse power motor with 110 cord do we half to rewire inside the motor

[@stevem53]

I intend to buy the plans. Question: Is it better to use an 1800 rpm motor and vary the speed over 900-4000 rpm, or use a 3600 rpm motor for the same speed range? The motor would be 2 hp, inverter duty 3 ph in either case. Thanks for you response

[@HouseMadeUS]

I only use 3600 RPM motors. Much better speed range.

[@garetkonigsfeld2]

I know this is kind of an older video. But I can't find any good video showing how people set the red jumpers. The reason I ask is because I don't feel like I'm getting the full power out of my VFD. Power at the cord is correct but no mater how I set the start up it's slower than my other type of VFD with a longer wind up time. I don't quite understand where it's saying to place the red jumpers for 220. I'd just like to see a close up of the red jumpers. I'll watch again maybe I over looked you setting them. Thanks for your time.

[@josh4058]

If you find your motor is running the opposite direction that you want couldn’t you just switch the black and white wire in the vfd? Is there any reason to do it one way over the other?

[@HouseMadeUS]

what should I do(can it be normal) for my motor to come with No instructions No labels No wires coming out I'm using this motor for a different application, But I'm assuming the wiring should still be the same the most I can see this thing has is 2 main labels directly on the motor. One is a warning label and the other is The spec label which says NBK 20609 1/4 hp 115v 60Hz (PH1) (SF1.35) 1725RPM Reversible (CL.B) (AMB) 40°C Continuous Thermally protected (the parenthesed are the ones i dont know there meaning, can anyone tell me there meaning?? i think PH1 means single phase?) same label also has a connection diagram which reads simply RED____○5 BKACK___○2 ○4____ LINE 1 ○1____LINE 2 under a faceplate on the motor I found some kind of interface with 3 open pairs of prongs 2 of which has a nut an bolt I assume for a loop connector(if choosing that route)along with 2 single prongs with a red an black wire attached that leads toward the Stator, on the outside is a yellow green lined wire for the ground, and that's it. I see total of 6 numbers pointing to the prongs, with line 1(○4) and line 2 (○1) each pointing to a pair of prongs Each are the ones that has the bolt and nut other than that. I see a couple other numbers(6&7) that point to small open holes then an extra pair of prongs that say 3. But I don't see anything that says what three does. I'm no electrician but had the motor come in the condition that you had yours in. I could easily wire it up. But I have no idea what leads to where or what goes to where especially given the fact that if what you're saying i's true then I can't rely on the colors of the wires which is what I was banking on until I saw this video. I mean, I know definitely what the ground wire is. But it safe to assume the black wire is the negative and the red is live. But even if that were true, I don't know what line one or line two means Nor do I know which prongd would connect to the red or black wire which are connected to the prongst they're not open so I don't know now😬 You are anyone else's help would be very much greatly appreciated PS. I'm going to try to contact the seller on Amazon, but the amazon site contains some more specs about the motor but nothing on how to wire it up.

The only reason to do this is if your grinder is running reverse in the forward position. All you do is put the black wire where the white wire is in the motor case and vise versa.

[@born2late568]

Iron Horse buyers be aware...these are cheap motors from China. Ive worked with crap tons of these and have found that the windings in these produce noisy and leaky frequencies. What happens is the bearings end up arcing out and pitting that results in extremely noisy conditions. I ended up changing all these motors over to a hybrid ceramic bearing that has eliminated this problem.

[@woodwoman9130]

Both the electronic components are not available which are the hardest to compare. Why don’t you offer the complete set up it’s useless without a motor

I can only guess that Brian would have the same logistical problem that AutomationDirect would run into, the supply chain has been suffering since the start of the pandemic. Also, he would have to invest more $ in order to carry the stock, kind of hard for a small business. AutomationDirect will take orders on out of stock items, I placed my order and they eventually fulfilled the back order but it did take something like 12 weeks, it could be longer.
