help with a stepper motor, trying to find a holding torque on a certain motor..

[brucer]

A friend of mine comes up and says, heres a stepper motor, I can get several of them if you want or need them..

the stepper motor is
Parker PowermaxII
P22NRXA-LNN-NS-00
BIPOLAR
35VOLT
3.3AMP
Po: 62watt
1500rpm


I have looked on the internet and cant find a torque rating for the motor, any help would be great..

If they are surplus (and they probably are if they are really cheap) you may have a hard time finding any info for them. If you have one on hand you could always test it by powering one coil (this is the worst case) and clamping a lever to the shaft. Add small weights to the end of the shaft until the motor lets go, then measure the total weight and the length of the lever.

You could also find a similarly sized motor online and see what it's stats are, they will likely be similar.

This s crazy!

I searched just the part number, I see them all over the place but never a mention of the torque spec. Maybe try calling one of the companies that sell them.
