Can anyone help me identify my z axis stepper motors. They are from a blue and white chinese 100 watt co2 900x600 laser. They have no identifying marks as regards volate or amperage. They do have a model number (which after 1500 google searches shows nothing other than who made them www.JMC-motion.com and even they cant help! ive attached some pics, if anyone thinks they might be able to help message me and i’ll post some dimensions. Thnk in advance
First of all, it is a type 57 stepper motor from China, which needs to be used together with the stepper driver
Whether the motor is open loop or closed loop, your picture is not very good, I can not tell.
I need to see all the wires on the motor
I looked at the manufacturer and they have a 54, but not a 57. Maybe an older motor. That’s the link above.
He appears to have the machine, but no mention of an issue except to ID the motor… This is in a 9060 100 watt laser, so he probably has the drivers. That should give you a clue about the current requirements.
The US National Electrical Manufacturers Association (NEMA) standardises various dimensions, marking and other aspects of stepper motors, in NEMA standard (NEMA ICS 16-2001). NEMA stepper motors are labeled by faceplate size, NEMA 17 being a stepper motor with a 1.7 by 1.7 inches (43 mm × 43 mm) faceplate and dimensions given in inches. The standard also lists motors with faceplate dimensions given in metric units. These motors are typically referred with NEMA DD, where DD is the diameter of the faceplate in inches multiplied by 10 (e.g., NEMA 17 has a diameter of 1.7 inches). There are further specifiers to describe stepper motors, and such details may be found in the ICS 16-2001 standard.
