8-Wire Bi-polar or Uni polar,

425 oz in.

1.8° /200 Steps Per Rev.

2.8 Amps Current Per Phase ( Bipolar Parallel) 4.17 volts and 6.8mH.

Attached is the PDF with the full specifications.

I believe it will work, but I want to be sure.

Thanks

My plan was to have it driven indirectly with a belt and pulley, and beyond that I'm at a loss for what motor would best suit my needs. I have practically no electrical or electronics experience.

I ran into an issue with my 1515 lead cnc machine...

I finished the setup and powered my machine, but soon found out only one Y axis motor (Nema 23) was working...

I then turned off the machine, and turned it back on again, and everything worked perfectly.

Everytime I turn on my machine, one of the two Y motors (its not alway the same side, but it seems to have a preference for Y2) won't turn on (there is also the (!) sign on the BlackBox X32 controller)... I then have to turn...

I’ve noticed some strange behavior with my stepper motors after turning on my controller to set up my new spindle, without moving any of the motors.

If I leave the motors idle for too long, one of the Y-axis motors shuts off completely. This doesn’t happen if I start using the motors right away—it only occurs when the machine is turned on and remains idle for a while. Interestingly, it’s always the same motor on the Y-axis.

On my BlackBox X32 Controller, a red light appears on the...

I am putting the BB and the power supply in a steel box with shielded motor cables. Everything I've read it seems like we're trying to protect the Controller from EMI so should I put the BB in the steel box by itself. I've also heard about how bad USB s are so I've been using WIFI, what's the best the interface?
Well this is a start I am taking every apart and trying to stop and avoid as much EMI as I can.

Is there a 24V (.5a) source available on the X32 that would accomplish this?

Max Slewing PPS: 2500 PPS
Max Starting PPS: 2500 PPS

Step Pulse Time is in micro seconds. There are 1,000,000 microseconds in a second (1/1e-6).

So I think that Step Pulse time = 1000000/2500 = 400 microseconds?

The default value is 10 microseconds..

I am looking into power supply for this motor. On the product page, it states 24-48VDC (Recommended).
As you know, most power supplies are 12V or 24V. How can I tell if 24V is sufficient? If I want to drive it at the highest torque, is 3A the maximum current I should supply before the motor gets damaged?

Also, are there gears inside this motor to make it about twice more torque than the standard NEMA 23 sold in the online store?...

I bought my spindle and VFD 5 years ago and never used them, however I've now fitted them on a CNC router and the VFD failed so trying to add the VFD YL620-A2.2KW 220V but don't want to damage the spindle.

I have done a factory reset P0.13 =10

many thanks
