STEPPERONLINE Closed Loop Stepper Motor 1 Axis CNC KIT 3.0 Nm/424.92oz.in Nema 23 Motor & 0-8.0A 24-48VDC Closed Loop Stepper Driver CL57T V4.1

These are quality solid motors. We have them on a heavy long arm quilting machine and they have performed perfectly. I would definitely buy again. I do not know any of the technical data as my son, who is a mechanical engineer, installed and did all the connection and calibration.

StepperOnline is a quality and longterm supplier of CNC motors, controllers, and other accessories. I have 3 CNC machines and use StepperOnline gear on all of them after trying other manufacturer's gear. Highly recommended

Excelente motor muy eficiente

After hooking it up like they say, the driver would just freak out, make some noise and shut off, finally got the thing to work in open loop mode. Started the return process, and while waiting, found online several issues with the encoder cable being wired wrong, indicated by the driver showing 7 red blinks when in closed loop mode. The solution is to rewire the encoder, or reverse the motor. See picture- wire it this way if yours doesn't work, not the way the manual sais.

I'm using two of these on a CNC converted G0704 mill. They work great. I set them up to 800 steps per revolution and they seem incredibly smooth and precise. The hall sensor works great and the stepper motor smoothly catches up after binding. I found out the hard way that you need true HD15 connectors that have straight through wiring. While VGA cables share the same connector, you cannot use a VGA extension cable because of the cable wiring and connections do not match. Looking to build a 4th axis and plasma cutter. I'll definitely use this motor and controller again.

Easy to set up and connect to the driver. more specs are available on the manufacturer website along with 3d models if you need to fit the motor in a custom designed project. The motor doesn't slip and isn't too loud when running at 16 microsteps. The noise is noticeable in a computer science lab environment at speeds around 1500+ pulses/second but is almost silent below that. The driver is completely silent to my ears.

The stepper encoder connection was not wired correctly on 4 of these steppers I purchased. I did a continuity test on each wire and it confirmed the manufacturer soldered the DB15 plug upside down. I don't know if its just the wire to the first DB15, or the wiring inside the encoder itself. But this purchase was a waste of $$.

Good quality product.
