Stepper motor specs

Hi
Would these stepper specs be OK for a prusa mendel. or would they not have enough torque as I think the V is a little high.

Step angle 1.8, Rate Volts 3.4V, Rate current 1.7A, Phase R 2R, Phase inductance 3mH, Holding torque 48oz/in, Rotor inertia 54 g/cm sq

Torque .22 kg/cm, motor weight 240g, 4 cables.

As here [www.ebay.co.uk]

Thanks.

Those specs look pretty similar to these, which is the motor I use: [www.zappautomation.co.uk]
I think voltage isn't too important, the stepper driver sorts it out. Amps are more important, and your motor looks to be in the right range.

Thanks for the info, that is where I have bought them from before but it would be nice to have another opinion regarding the torque as I will putting these into a Mendel 90 ( Nophead grand design) I have followed his blog for that last 2 years.

I have built all the MDF parts and designed all the ABS parts with a 70mm spacing for the X and 30mm for the Z. all with 10mm bearings everything is printed and I am looking forward to see it running.

I have decided to go for Zapp auto motors as I am thinking that the torque is aabout 20% higher. The Mendel 90 is now just waiting for them to arrive.
