NEMA17 Stepper Motor (HS17)
Product Overview
The NEMA17 (HS17) is the most popular and widely used frame size in the stepper motor industry, featuring a 42mm × 42mm faceplate. Adampower's HS17 series offers a comprehensive range of models with holding torque from 0.160 N·m to 0.500 N·m across motor lengths of 33mm, 40mm, and 48mm, making it the go-to choice for countless applications in 3D printing, desktop CNC, robotics, and general automation.
The HS17 series includes eleven distinct models with carefully optimized electrical characteristics. Short-length options like the 17HS3601 (33mm, 0.160 N·m) provide a compact solution for space-constrained designs, while longer models such as the 17HS5604 (48mm, 0.280 N·m) and 17HS5425 (48mm, 0.480 N·m) deliver more torque for demanding applications. The diverse range of rated currents (0.4A to 2.5A) and voltage ratings (1.8V to 12V) ensures compatibility with a wide spectrum of stepper driver technologies, from low-voltage A4988-type drivers to professional-grade DM542 and similar drives.
NEMA17 motors are the industry standard for motion control in the maker community, light industrial automation, and professional equipment. Adampower's HS17 series undergoes rigorous quality control to ensure consistent performance, precise step accuracy, and long operational life. Each motor is wound with high-temperature rated copper wire and assembled with precision bearings rated for tens of thousands of operating hours.
