This small size 28mm NEMA 11 stepper motor with 51mm body length has a good torque output 0.12Nm/17.04oz.in, which is combined with a 1000CPR incremental optical encocer & a gear ratio of 14:1 planetary gearbox. It is absolutely an ideal solution the applications require closed-loop servo control and low speed/high torque output.
