Conect lathe stepper motor ID

[DerryUK]

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.

Well thats helpful in doing the conversion from Sigma part # 20-3424D200-F1.8 The 3424 is width/length 3.4"/2.4" so these are Nema 34 size, the 200 is steps/rev and the 1.8 is probably phase amps as surmised. The HY200-3424-0170 is a 1.5Nm when wired bipolar parallel. This is higher performance than mentioned for the Sigma part so I guess thats a later (yet also now obselete) drive.

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
