Hi everyone,
I am looking for high performance stepper motors for a project where I am trying to minimize the size of the device. Essentially, the Nema size of the stepper motor directly determines how flat I can design the device (the length of the motor is not important and the price is secondary). Now, the stepper should produce at least 0.27 Nm (= 38 oz-in) of holding torque and hold that torque well until about 400 rpm. The best I could find for these requirements was the Nema 14 stepper from oyostepper.com: https://www.oyostepper.com/goods-15-Nema-14-Stepper-Motor-Bipolar-18-deg-14Ncm-20ozin-04A-12V-35x35x26mm-4-Wires.html.
and I am looking to reduce the size even further beyond the 35 mm that this motor offers. Any suggestions on where I can find a small but powerful stepper (perhaps a Nema 11 with similar performance)? Or any ideas for other alternatives?
