I’m in process of constructing a rotary for my laser. I am trying to rule out whether I can use a NEMA 17 stepper motor I have in hand, when the laser cutter likely is sending power for an expected NEMA 23 stepper motor.
I think my 100w laser cutter from omtechlaser.com uses “NEMA 23” Stepper Motors.
The existing Y axis stepper motor is definitely a 2-phase motor. That’s known both by examining the aviation style plug (4 holes, not 3) and info from one of the seller’s websites.
According to some NEMA 23 specs on this site: NEMA 23 Stepper Motor Datasheet, Specs & Applications
“Each phase draws 2.8 A at 3.2 V”
Now, I have some NEMA 17 motors that are designed to draw 1.5 A.
However, according to the above website I used for specs earlier, the NEMA 17 specs shown are:
Rated Voltage: 12V DC.
Current: 1.2A at 4V.
My bottom line question is, would I burn up a NEMA 17 motor if I connected it to the laser machine’s wires that are routed to (apparently, normally) a NEMA 23?
My sense is I would overheat the motor, but the details of electricity and motors are way outside my wheelhouse.
