Diy Brushless Spindle

[njhussey]

Well bought the motor today, got a 320kV one http://www.giantcod.co.uk/xyh5065-32...-p-404606.html so hope to have that early next week! Still waiting for my bearings from the US, been over a month now :-(

Still will give me a chance to finish off the bearing housing!

My intent is primarily to machine aluminum and hard plastics. I'm designing for 500-4000 RPM with hefty torque to use with 3-12mm end mills.

Anybody have an idea if these type motors will deliver decent torque at 500 RPM?

i dont cut with a 12mm endmill however i do cut a lot of acetal/delrin and a bit of alli with the larger of these spindles(250kv) 2.5mm to 6mm + fly cuting without any major problems, i personally believe you would struggle to make use of any more low speed power/tourque without having your gantry shake rattle n roll

thats asuming your going to run it on a router ?

i just had a look at where you live to see if it was worth nipping over to you so you could try one :lol: san francisco !!! thats a looooooong way LOL sorry man
