i want to build a small cnc lathe, i have a 120mm chuck and i’m planning to use this ac-servomotor, i have no idea if it will work. what do you think?
i’m guessing i’ll have to set it open loop…
@iuliancalin That motor looks like a beast. What controller do you plan to use? I don’t quite understand your comment about setting it to open loop. I didn’t see anything in my very quick scan of its specs about it being open or closed or either one.
Pardon my ignorance but is it normal for a CNC Lathe to use a servo as the drive motor? My lathe uses a bi-directional drive motor.

@gwilki , a servo motor is considered a closed loop since it has a feedback sensor, i believe its a hall sensor, not sure. you probably thinking of a stepper motor, that one is different
also, it doesn’t need to be closed loop since it will spin a spindle shaft. the only thing is, if you take a look at the plugs, the CN1 is the pul and dir , the CN2 in the feedback loop
also @whitewolf, a Stepper motor or a Servo one can spin both directions , and your question was basically my question above just different
also i wasn’t sure ether and wanted to know if someone else had the idea to try, or maybe even more understanding of this type of motor, i only have had in hand a closed loop stepper

Gotcha, misunderstood. With that speed and torque, it should “work” but not sure that it would be the right choice as opposed to a more standard motor but if you have a specific application then go for it.
I am familiar with both stepper and servos as I used them both in my robots and projects. I only specified a bi-directional AC motor as these can be manufactured as both uni and bi direction.
My lathe spins both although I have only ever used it in a single direction.
