For applications that require a high torque, Nanotec offers new planetary gearboxes in two sizes and many reductions: the GP42 gearbox is designed for all motors with NEMA 17-flange, as well as the DF45 external rotor motors from Nanotec. The GP56 gearbox can be combined with all brushless DC and stepper motors in sizes NEMA 23 and 24 (56/60 mm).
