NEMA17-05GM
The NEMA17-05GM is a compact bipolar stepper motor with an integrated 5.18:1 gearhead. Thanks to its reduction ratio, it is particularly well-suited for applications that require precise movements with high torque, such as in automation, positioning, and robotics projects.
With 200 steps per revolution on the motor shaft and, theoretically, 1,036.36 steps per revolution on the gear shaft, the motor enables exceptionally fine-grained movement. The integrated gearbox thus not only improves power transmission but also increases the positioning resolution at the output.
The gearbox operates with a reduction ratio of 5.18:1 and a specified efficiency of 90%. It is designed for a maximum permissible torque of 3 Nm and a maximum permissible holding torque of 9 Nm, providing a robust foundation for high-torque applications.
With dimensions of 42 × 42 × 70 mm, the NEMA1705GM remains relatively compact despite its integrated gearbox. The JST-compatible connector further simplifies integration into existing systems and makes the motor a versatile solution for precise and powerful drive applications.
