im looking to get 2 identical large stepper motors must be 5 , 6 ,8 wire set up not 4

i would like to mount motors directly on the mill drill lead screw

double shafted would be a bonus

anyone know anyware to buy some at a good price

j-fetting has some but they are 4 wire wich will not work with fet-3

[ger21]

What's a good price? Vexta has some for about $140.

I bought a 650 oz-in steppers for $79.95 new!!

I went to Web-Tronics.com Those motors you bought were 450 oz-in steppers for $79.95 new!! You had me excited about 650 !

[davereagan]

OK,
I looked further at the description, not the product code and realized the holding torque is 665 in. oz. I am the one in error.

Motor number 8 on the list, 425 ozin torque, 8 wire with a double shaft. $54 USD

+1 for Keling motors. THe 425oz-in motor is great. I got that thing running over 1000RPM during testing.

Here I tried to paste a short cut for you the price is still the same as it was when I bought them. web-tronics.com / motion control / Stepper motor Nema 34 (85BYGH450B-03) if the shortcut didnt work.

Anybody with some experience/information on the webtronics steppers? I'm just starting to gather info, but one thing I noticed... They now list 85BYG450B as 665 oz-in, and the spec sheet attached claims 6.0v/2.0A. Somethings screwy, and even though my first guess would be the claimed 665 oz-in, it seems wasteful to put a 12w/phase motor in such a large package.

I had been eyeballing their 874oz-in for X&Y and the 277 oz-in NEMA23 for Z on my RF-31 until I noticed that.

The holding torque is a very poor parameter to judge a motor by. What matters more is the phase inductance. If it's too high, you won't be able to get any useful speed out of the motors.

I think all the high torque (ie: >1000oz-in) motors are a waste of money for a typical cnc application. They will deliver much less power than a 400 oz-in nema 34 one.
