  • Directly Fits Nema 17 Stepper Motor: considering the wide application of the stepper motor, this harmonic gearbox comes with a customized flange to connect with Nema 17 stepper motors.
  • Easy to Assemble: compared with most harmonic reducer in the market, we optimized the structure and connection method of the speed reducer, it does not need to assemble the units of the harmonic gearbox, you only need to connect the stepper motor to the reducer, ensuring the accuracy and stability of the reducer.
  • Main Specification: Reduction Ratio: 50:1, Torque at 2000r/min Input: 7 Nm/ 5.16 ft·lb, Peak Torque at Start and Stop: 23 Nm/ 16.96 ft·lb, Max Value for Average Load Torque: 9 Nm/ 6.64 ft·lb, Permissible Max Momentary Torque: 46 Nm/ 33.93 ft·lb, Permissible, Max Input Rotational Speed: 8500 r/min, Permissible Average Input Rotational Speed: 3500 r/min, Moment of Inertia: 1.4 x 10-2kgc㎡, Backlash: less than 20 arcsec, Design Life: 7000 hours, Weight: 0.5 kg/ 1.1 lbs
  • Why Harmonic Reducer: harmonic reducer utilizes a unique operating principle that is based on the elastic mechanics of metals, comes with the advantages that the harmonic drives approach to features like low backlash, compact size, excellent positional accuracy and repeatability accuracy, compared to other reducers (like planetary gear reducer), strain wave harmonic gearing is widely used for industrial robots, CNC equipment, medical instruments, and the automation industry.
  • There are 3 reduction ratios (50:1, 80:1, 100:1) to choose from. If have any questions or need files, feel free to contact us.
