110V 1.5kW Spindle With VFD Setup Guide and Testing

You deserve more subs, I'm building my own cnc and these videos are useful

[@MD-hu3il]

Thanks man, I'm glad the videos are helpful!

@@MD-hu3il I'm actually struggling with something you might be able to give me some advice on... I'm buying a 1.5kw spindle and am going to run it with vfd but it says it only runs from 8000-24000 rpm, I need the lower rpms so I don't understand why if its run by a vfd this limitation is here... I'll link it: www.amazon.co.uk/VEVOR-Spindle-Cooling-Engraving-Milling/dp/B08C2QG74X/ref=sr_1_2?dchild=1&keywords=1.5kw%2Bspindle&qid=1614259849&sr=8-2&th=1

[@MD-hu3il]

Im no expert but from my understanding you run the risk of overheating the windings. As speed decreases the cooling fan becomes less effective and (i believe) more heat is generated. The spindle can be programmed to run at lower speeds but you can find lots of accounts of guys burning out their spindles while cutting below 6000 rpm. What kind of speeds are you looking for? Whats the application?

@@MD-hu3il that's a good point however there water cooled spindle have the same strange rpm rating, well I think it's strange... Do you think I'd be better off getting a water cooled spindle if I'm running low speeds and feeds?

[@canardsalle7731]

Wow thanks for the trouble of making this video. I totally got mine to work in no time!!!

[@MD-hu3il]

Awesome man! I'm glad to hear it

[@ronessex6682]

Thanks! I just got the same VFD and video helped and your spot on with the setting. I did however go back and read the manual just to get familiar with it.

[@user-fj5he1ei4y]

my spindle just got smoke getting out today, it was good i test with the original vfd setting. i have 110v version, and i did a restore setting to my vfd. i think the factory setting defult is for 220v. when the hz going up, my spindle sheild wire is getting smoke and the spindle became hot.

[@Festivejelly]

You should be using crimped connectors with mains wiring.

[@DustinColemanCHMS]

Hi, I could not find the video where you show how to set up this VFD to be automatically turned on and off from the CNC's controller. Do you have a link? Thank you!

[@teodormircea]

I have the same spindle. What it bothers me is the lack of ground connector on the spindle

[@MD-hu3il]

That is definitely an issue, I considered grounding the body on mine.

[@muskokamike127]

@@MD-hu3il To be honest, the body of the spindle should be grounded to the cnc gantry, so you should be able to simple run a ground wire from anywhere on your cnc to the case to the ground wire on the vfd.

[@victorloera9]

Thanks!!! Great video!!!

[@rayjohnson4395]

I did everything but I don't have potentiometer control, it run straight to 24,000 rpm quickly, I have PD001 and PD002 both set to 0 Everything else set to match info plate on motor. What do you think I'm doing wrong. I have jumper on 2 - 3 vr. The first time I hooked it up Everything worked but it would on get to 12,000 rpm probably because it was set to 4 poles and I have 2 pole motor, but potentiometer worked. And it took 10 seconds to get to speed now it gets to 24,000 rpm in 2 seconds

[@watsonstudios]

I'm thinking about getting a spindle to replace my router and want to know what's the advantage of a 220v over a 110v. Is it just power & torque? Would a 110v 2.2kw spindle work just as well as a 2.2kw 220v spindle?

[@MD-hu3il]

I'm not sure. I don't have a 220 circuit available so it was off the table for me. 220 should run more efficiently though. I have had some issues with cooling on multi hour, sustained spindle load. 220 would be slightly better on that front generally speaking. I'd go 220 if it's an option personally.

[@Levisgil47]

Hello, tha,ks for the video what mounting plate did you use to install your spindle? Thanks

[@MD-hu3il]

Sure thing man, I'm working on a video showing how I installed the spindle right now but here's the important part. I printed a new Z axis (grabcad.com/library/1-5kw-z-carriage-v1-1). It's not perfect but it got me up and running quickly! One note is that I removed the bearings from the old carriage but they fought me all the way, if you don't have access to an arbor press you might be better off buying new bearings online. Let me know if you have any thing else you'd like to see a video of, I'd like to make videos that are as helpful to people as possible.

[@MD-hu3il]

Here's the video if you're still interested! kzbin.info/www/bejne/qYekoYmMp9h3fpo

[@Xander054]

Could you please let me know the lowest RPM it can run at? Can it sustain 1000RPM without overheating. The concern is the cooling fan won’t run fast enough

[@MD-hu3il]

I don't run it below 6000 and I generally don't cut below 8000-10000. It all depends on the load. If you're at zero load maybe it would be fine at 1000

[@canardsalle7731]

6,000 me too

[@jesolitojunio4074]

Hi sir how about the spindle not run or work

[@jamescullins2709]

how long can you run this spindle before overheating?

[@EnergySeeker]

hi am getting error ELu 5 what am i doing wrong >?

[@MD-hu3il]

I wish I could help but I havent seen that error, a quick Google shows some people have gotten replacement vfds after that error but at least one person solved this by correcting a wiring issue in his supply voltage with a 220v system. All that is to say im not sure man. Hopefully someone else can chime in with better input than I can give on this one

[@EnergySeeker]

@@MD-hu3il so the input voltage have to be 220v i was using 120 that is why thanks a lot

[@MD-hu3il]

No that was just the only example I saw online. My input voltage is 110 not 220 if you have the same vfd and spindle I have you will only need 110.

[@EnergySeeker]

@@MD-hu3il its says 0-220 volts 11 amps on it mine is 2.2 kw model

[@benzhuk876]

How does the sound compare between the 400w and the 1.5 kw?

[@MD-hu3il]

The 400w i had was almost as noisy as a router. Compared to that, the 1.5kw is a whisper. The noise from the spindle its self is comfortable with no hearing protection

[@Eric-yx1gs]

I’m setting up my first cnc and of course I wasn’t to sure what I had purchased. I ended up with a 110v 2.2kw water cooled spindle and a vfd. I ran a 12/2 wire and added a 120v 15amp outlet. Will the machine run on that or do I need to swap out my wire, outlet and breaker for 220?

[@RandomMan1]

You need a 20A breaker for 2.2kw @ 110V (110*20=22000). In general 220v would be preferred. It's better to run more volts than amps, the risk of fire and overheating problems are less, since you're not at the max ampacity of the wire. 12 gauge Romex wire is rated at 20a, so you should be fine with unless you messed up a junction somewhere though.

[@RandomMan1]

Actually for a real 2.2kw motor you would need more because of start up current draw, but these Chinese motors are so very over-rated from what I've seen. (Like the 2.2kw rating is a big exaggeration in my experience)

[@hosr888]

Dude nice music, what is it?

[@jdy5556]

I have the same setup and think I have things correctly hooked up however the max RPM's I can get is just under 12000?? It's rated for 24000. Could this mean something isn't wired correctly?

[@satgod]

I am having the same issue

[@daverassbot5869]

Same issue here..

[@muskokamike127]

Now I'm not an electrician so take this with a grain of salt but a 220v service is just two legs of 110. So if you have 2 circuits running to your garage, you have 220. For eg: in your breaker box, if you have two single pole breakers for the garage side by side, and you have an outlet with a split (red black white and ground wire) and the tab is broken off connecting the two outlets, you have 220v running to the outlet. Just change the duplex recepticle to a 220v 20 amp 3 wire and voila. Now the "proper" way is to replace the two single pole breakers with a 20 amp 2 pole, so if either leg has an issue, they both trip, but it does work. I did that when I picked up a stacked apartment washer dryer. I had 2 free 110 breakers and just wired it up that way.

[@RandomMan1]

I've never seen 2 circuits wired to the same box, usually the tab is broken of to make one of the outlets switched

[@muskokamike127]

@@RandomMan1 well, the tab is normally broken off so each outlet is a separate circuit with its own breaker. The vast majority have one circuit and one breaker though. All the ones in my shop are wired independent (top outlet 1 circuit with its own breaker and bottom with it's own breaker) because many of my tools have a huge spike when turned on. My compressor alone pulls 13 amps when it kicks on. Same as my table saw, miter saw etc. Each outlet got a 12/3 run to it, shared common, individual hot.....

How i can reach you, for an advice

[@razvantrece1501]

Hello, I just made my CNC and on my first test something does not seem right. The CNC uses 2.2 KW air cooled spindle at 300 Hz speed. and a Makita drill bit with one cutting teeth as you can see in the picture from the end of my video. Could you please explain why do I have that whistle noise when it cuts? Also the spindle motors is getting very hut, after the cut I could barely hold my hand on it? Cut federate is 800 . The diameter of the drill bit is 6mm. kzbin.info/www/bejne/mqS1fIWraNV7eNk
