Thread: Conect lathe stepper motor ID
I have a conect lathe with no electronics and this motor attached on the x axis:
and an unmarked smaller motor on the cross slide.
I can't find any documentation for the motors on the web. I'm guessing that the 1.8 at the end might indicate current per phase.
Does anyone have one of these lathes and/or data on the motors? I'm trying to specify driver electronics and need to know what drive voltage & current they need.
As best as I can find: 1A coil, 200 step, 110oz-in. Drive voltage is immaterial, they'll be a 3v - 5v coil, but any modern current limiting driver will do the job. High inductance probably so go for 30V at least. Or better, check with what others have done...
If you can afford it replace the motors with the modern square type, those old round ones are really last century technology. There have been great strides made in motor technology in the last few years.
It will pay off in the long run is speed and reliability.
Every Denford we have done we have had to swap motors to get anything like decent speeds out of them even with decent drivers and high voltage.John S -
1.8 I'd guess is step angle, which equates to the normal standard of 200 steps per revolution suggested by Irving above.
My Conect is a beige one, and used different motors, however I think the controls were pretty similar, so I'd doubt they would change the motor specs too much between the versions. The motor details for mine are in the first couple posts at http://www.mycncuk.com/forums/mills-...ion-grows.html
Or take John's advise, and let me know how you get the motors of the ballscrews!
The motors on my Conect lathe are MAE HY-200-2220-100 A8 for the cross slide and HY-200-3424-170 A8 for the leadscrew.
On the larger motor it also says 1.7A and 1.7ohms.
Although my lathe is still in bits I am going to use the original motors.
Here's a data sheet: http://www-app.etsit.upm.es/departam...pap_hy_lab.pdf
A suitable modern replacement could be this one on eBay, however I'd consider redrilling the mounting plate and using a modern Nema23 which will do the same job and be lighter/quieter/cheaper... for example this one
The cross-slide motor therefore is a 2.2" (Nema23?) 200 step, 1A per phase, and from the data sheet, 0.7Nm... A modern replacement might be (check the hole dimensions) this one
