Hi guys, I know this is somewhat of an old thread but I registered on this website because of it. I am looking everywhere for those C10, ER20, 100L collet chuck but I can't seem to find one... only found the 50L version and it isn't long enough for the outrunner I bought. I will try reusing this 50L somewhere else, but I need a 100L and was wondering where to get one? I'm trying on eBay, but I can't seem to find any, must be because I live in Canada...
If someone knows where to buy one new C10-ER20-100L collet chuck, please reply to this post, or if you own one and are willing to ship it to me that would be awesome! Thanks a lot and I hope I'll be able to make this DIY since it mimicks exactly what i've been looking to do
This is an ER16 collet chuck, I need an ER20 collet chuck, but thanks silyavski :)Quote:

Here is the link, for those interested in Canada (might work elsewhere too, but wasnt working for me with a .com.uk):
http://www.ebay.ca/itm/111501420293?...84.m1439.l2649
That's the seller I bought mine off....arrived quickly if I seem to remember correctly.
Yup, that link was from you, I just modified the .com.uk to a .ca because it wasnt working for me. I hope it doesn't take too much time to arrive here :)Quote:

Thanks in advance
What you trying to cut? This will influence what KV motor you use etc...
Hi there,
i'd like to be able to cut alluminium but also softer stuff like plastics and wood. Do you think it could be suitable for steel also? i thought it would be too weedy?
You'll never get one spindle to cut everything. Steel needs slower speeds, typically a few hundred rpm up to a couple of thousand, what it really needs is torque and lots of it! Wood and plastic on the other hand need higher rpm and feeds. You're best not thinking about steel on a router and just buying a mill if you want to do steel. In all honesty you're better off buying a 2.2kW water cooled spindle for just under a couple of hundred quid which will do all you want with consument ease...I've got a home made brushless spindle and I've not bothered using it. I will do on something but not sure what yet...
If you still want to make one then use a feeds and speeds calculator to work out what speed and power you want for the materials you're wanting to cut and then look at something like a 5565 brushless dc motor (look on hobbyking) 170kV to 270kV outputting approx 2kW coupled to a 100A ESC.
Cheers Neil,
Exactly the kind of info i'm needing

Hi guys, sorry to "revive" this thread, but I would like to know if somebody has been able to control this kind of spindle (outrunner with an ER collet) with an Arduino UNO to be able to achieve precise RPMs? As this would make it much more practical for the kind of use I want to make out of it... if so, how did you achieve it? Would it bother you sending the line of codes / diagram / pictures / videos or anything else to show what you did and all that? I am a newb when it comes down to electronics and really want to achieve this ! Thanks !!
Everything I try to go to on that site asks for a password, is it still live?Quote:

The VESC will hold the RPM very close under varying loads. I've only tested it on 6S batteries, but my CNC runs on 42V so that should be close to getting it to speed.
I cast the adapter tube in Urethane (again, stuff laying around). A lot of work, but not bad for only needing to spend $20.
The VESC BLCD software will show volts, amps, etc. live if it's hooked up via USB. I always thought it would be a neat idea to slow the feed rates down based on load. I'm running LinuxCNC but have no idea how I'd hook all that up.
did you attache the stub directly to the motor? or did you build bearings between them?
I put 2 additional bearings on the stub and then a coupler from the stub to the motor. It's all held together by the casting. Everything lines up good, I just made a solid couple (no flex) hopefully that will be ok. Can't wait to try some actual work with it.
What maximum rpm can be achived with external rotor motor
can I use VFD for speed control
I found 90 watt 415 v 50 hz external rotor motor. What
capacity VFD it will work with and max rpm
Regards
I recently bought a cheap Chinese CNC machine and I wanted to replace the stock 555 motor it comes with something like what you guys have shown. Max diamater for the motor that I can use is around 36mm for an inrunner and 35mm for an outrunner and uses a 25mm hole spacing for mounting the motor. I just want to be able to cut acrylic nothing else. what motor would you guys recommend?
Hi all
would this be any good as the motor, it has 10mm shaft and 200kv. I found a spindle that is 10mm URL="https://www.amazon.co.uk/dp/B07Q7473NH/?coliid=I1PB48BH2P8JSU&colid=1WM4D42BOQDI4&psc=1&r ef_=lv_ov_lig_dp_it"]https://www.amazon.co.uk/dp/B07Q7473NH/?coliid=I1PB48BH2P8JSU&colid=1WM4D42BOQDI4&psc=1&r ef_=lv_ov_lig_dp_it[/URL]
any other good ones around
Ta D
...I know it has been 10 years since the thread started... just wondering if somebody could make me one like Mark's with double bearing ?
I fancy doing a small drill press like this one -> https://www.youtube.com/watch?v=T-ieUwOoqgw
This will be used for drill wood and occasionally acrylic/ aluminium so maybe maximum of 4000 rpm.
