Re: Steppers

Run as fast as you can away from those 24V motors. Here is a rule of thumb.
The higher the motor coil voltage rating ( not to be confused with the power
supply voltage rating) the slower the motor will run. The reason is
inductance.
Some manufaturers don't need much speed so they look for very low current
draw. The 24V motors usually only darw ffrom .2A to .6A

for example a 6v 1A motor will run a lot slower than a 1V 6a motor . On a
36VDC power supply the ^v motor may run at ~300RPM max. The 1V motor would
probably run about ~900 RPMs A 24 V motor would be luck to run at 90RPMs
