I am currently sourcing stepper motors for my prusa i3. Is this motor ok? The holding torque looks alright (5.0kg/cm) but the motor is short length is only 34mm.
Is it fine?
No. Those are unipolar motors, and all standard printer electronics requires bipolar motors. Bipolar motors also provide greater torque. It might be possible to dismantle and modify those motors to be bipolar by disconnecting the centre taps, but save yourself the bother and buy bipolar motors.
