In some situation, the machine need a low speed or high torque output from NEMA 17 stepper motor so a NEMA 17 stepper motor integrated with one gearbox(reducer) will be a good choice. Frankhumotor provides some kinds of NEMA 17 gearboxes from economy to precision types as below. NEMA 17 stepper motor with economy planetary gearbox is suitbale for the application that doesnot need accurate positioning. On the contrary, NEMA 17 stepping motor with precision planetary gearbox has better performances such as lower backlash, lower noise and longer lifespan. And the selflock can be achieved when the NEMA 17 stepper motor is integrated with a worm reducer(gearbox).
