Thanks Clive S,
you've saved me $420 AU. Does anyone else agree with Nema23 23HS45-3504S being the best choice for a steel gantry and Z axis?
that will likely weigh over 30kg?
I'm using these in a slightly larger machine, steel gantry probably weighs around 50kg, and I'm not expecting any problems. It's a very common setup. You do need to drive them with a suitable voltage - 60V or more.
Agree with 23's .. ball screws = 10 mm is ok (5mm better axial load deflection needs looking at )
I assume you are in Aust, so these links might be of assistance. Both are in Melb.
CHECK THE SCREW LENGTH This guy normally lists travel length ..
Thanks @Paul3112, saved in favourites. :)
This is the kit I ordered but had modified for my lengths: http://www.ebay.com.au/itm/331320314...%3AMEBIDX%3AIT
This is the motor kit I wanted to buy: http://www.ebay.com.au/itm/171994192...84.m1436.l2649
This is the motor kit I am considering now: http://www.ebay.com.au/itm/171937212...84.m1436.l2649
Before you start spending hard earned cash it might be better to do some research as these parts can make all the difference between a good machine and a duff...Clive
You are dead right about the affect of inductance on supply voltage, especially at higher RPMs. So I have found a reasonably priced torquey Nema23 model
inductance is 3.8mH - The lowest i've seen on ebay in that size.
What is everyones thought on this motor?
My 1000x700 build uses Mema 23 425oz 3amp at around £20 each, and they plenty of torque and speed, forgot to change DOC other day set to 3mm 6mm 2 flute for MDF (cuts MDF 6mm 2 flute at 15mm DOC Regularly), so ended up slot cutting 5083 aluminium at 3mm DOC 6mm 2 flute 1000mmpm FR, stepper torque was not a problem and it cut without incident but was working harder than it would normally.
