Need Help!- help with stepper motors

[surfjunkie]

hey. this is my second post, i hope i get as good a response as i did on the first one. OK, i found some cool stepper motors that i hope to use. they are SUPERIOR SLO-SYN type MO92-FD-8104, HOLD 300 oz/in, 200 steps/rev,
5.8 volts @ 2 amps.
i read a post that said i should connect (its an 8-wire motor) it for parallel windings for best torque/speed. but how do i know how much driver i need? is a driver rated at 3.5 amps enough? i plan to run them on a 24VDC power supply, and i know it controlls the current, but do i set the limiting resistor for the 2 amps, or is there a formula( there are lots of formulas i'm begining to realize) and i need to pencil some things out? what is the deal with the henries(inductance) of the motor? i had hoped to use the GECKO G540 drives for this, its a nice package and pretty simple,cost effective. will this work ?
im not asking for someone to do all the work, but if there is a post or web-page you can point me to to figure it all out...thanks!

Surfjunkie,

If the motors are rated at 2 amps, set the drivers for 2 amps.

A 2K set resistor will be required for each axis.

You will not get very good performance with a 24 volt power supply and those motors.

The old round motors like higher voltage, use at least 48 volts.

so, if you were building a machine, would you use these old motors, or just bite the bullet and buy new powerful ones that could run on 24 volts?
thanks

Surfjunkie,

I would run 48 volts or more with new as well as the older models.

Stepper speed is directly effected by voltage.

The new motors are a lot more efficient though.

The 2A rating is in all likelyhood the phase rating. In parallel it would be 1.4 the phase rating or 2.8A maximum. http://pminmo.com/PMinMOwiki/index.p...le=8wiremotors
