I was wondering if anyone out there could tell me the difference between wiring up the power supply to the drives in series or parallel. I have 4 drives,
and a 24v 4.5 amp power supply

Which is recommemnded?

I don't know which method effects current(amps) and voltage

series: 24v to all drives but shared (divided)current?
parallel: 4.5 amps to all drives but shared voltage (6 volts per drive)?
Is this correct or is it the other way around?

Which way gives more speed but less current per drive?
-or-
gives more current(for torque) and less speed(voltage) per drive?

I would rather have power than speed. how can I get more amps to the motors?
