RE: [CAD_CAM_EDM_DRO] volts?

Steppers are normally driven on 5 - 10 times the name plate voltage if you
are using a current limited driver. This is to help overcome the torque
drop-off that occurs with increasing RPM due to the inductance of the
windings. So, you don't need to find a 4.5 v power supply.

Take a look at the great white papers Mariss has on his site at
