CNC stepper motors are the one thing that seem to be an interesting area of the CNC machine. What I mean buy this is that the CNC Machine Stepper motors are not a real standard, like race cars, it seem to be, buy the most horse power you can.
In CNC Stepper Motors, horsepower is measured in oz and basicly is the amount of torque and the amount of holding power. So how do you decide on how big you need?
I was watching a video on iTube and noticed a person who put their home built CNC machine stats on the video as it was playing and they put that their stepper motors have 640oz holding. I was sure it was a typo and it was 64oz holding, but then when I saw their homebuilt CNC machine run at 120 inches per minute, I thought "Ok this homebuilt CNC machine may have 640oz".
But I paly in the NEMA 23 size motors, which is the mounting standard not the amount of power. I am use to NEMA Stepper Motors 23 in the holding power of:
CNC Motor with 495oz
CNC Motor with 425oz
CNC Motor with 282oz
CNC Motor with 270oz
CNC Motor with 185oz
CNC Motor with 156oz
So buy as much oz's as you can afford, it is like in a computer, you want to improve speed in your computer, increase the RAM, this is the same, buy as much oz's as you can.
I will be listing a group of places to buy motors as soon as I find them.
If you have any suggestions please e-mail me, I will assemble the better ones I find.
