This might be a long shot but does anyone have any idea of the specs/ possible replacement for this stepper motor?

4PS Precision & Speed
PST342-1A8
Current 7.5 Amp
Voltage 1.73 Volt
1.8 Deg per step

What type of stepper is this considered?

• Permanent Magnet Stepper
• Variable Reluctance Stepper
• Hybrid Synchronous Stepper

I found an old listing for the company but there number is out of service.

Thanks

this looks like a "normal" stepper motor. Stepper motors have permanent magnets.
does t have 4 wires then look at the size and find a motor the same size if possible the lowest inductance ( for speed )
If you can find one the same current I would just replace it. Otherwise you have to adjust the current in the driver.
