I picked up these four Powermax II stepper motors (P21NSXC-LSS-NS-03) on eBay last week. They’re a lot heavier than I thought they would be and huge compared to my previous stepper motor. They have a holding torque of 116 oz-inch, which I learned is the number of ounces you could suspend from a 1 inch rod attached perpendicular to the motor shaft.
