What kind of Power Supply for my 6 N m NEMA 34 Stepper Motor

Using Arduino Motors, Mechanics, Power and CNC

I want to operate my NEMA 34 stepper motor that sadly has very limited documentation, only stating that it operates at a torque of 6 N m with a max current of 7.2A, with its driver MA860 operating between 18-80V DC or 30-110V AC. I've had success on running it with regulated power supply and it drew a current of 0.6A at 24 V at no load. Now, I want it to run on an unregulated supply as it is a part of a more compact system, and my question is :

  1. Would using an unregulated power supply, such as the pictures attached, be feasible?
  2. What voltage of power supply do I need for its operation? I'm worried if i use an unregulated power supply of 24V it may draw out too much current when it's operating with load. I prefer using a 24V as it is cheaper but I may opt for a 36V PSU if necessary.
  3. What kind of safety do I have to use for the circuit? The only thing that comes to mind is using a fuse.

Thanks in advance.

For the electrical specs of the motor you basically only need to know coil resistance and max current. Resistance can be measured. Max current you already seem to know.

The motor driver regulates motor current, so you don't need to worry about voltage damaging your motor. Not enough voltage is worse. It reduces performance at higher speeds.
Post your resistance measurements first.

Sorry that is a regulated power supply. Wawa answered the rest of your question.
