Re: 8-Wire Stepper wiring

Hi Stan,
Some info from a non-guru: With a stepper system, there are
generally three main components that need to be specified: The power
supply voltage & amperage rating, the stepper drive amperage &
voltage rating, and the stepper motor amperage (and voltage, but not
so much) rating.

A given series wound 8-wire motor will give the same performance at
half the amperage when compared to the same motor parallel wound, if
the supply voltage for the series wound motor is twice as much as
what the parallel winding gets. Thus a stepper drive that could
handle 1.5A/phase at 48V (max on both Amps & Volts) would give the
same performance for the series wound motor, as a stepper drive that
could handle 3.0A/phase at 24V, when the motor is connected as
parallel wound. In this case, with two different drive amp/volt
ratings you can get equal performance from either type of winding.
Of course the above assumes that the power supply can handle the
given voltage/amperage.

Your stepper drive and power supply ratings will define which winding
method is better (while maintaining power/speed equivalance).
