Original Twotrees Brand Nema17 Stepper Motor. High quality Motor ensures better accuracy, step angle and torque. Specifically designed for 3D Printers and CNC.

The Nema 17 Stepper Motor 17HS4023 from Twotrees is a compact, high-quality 2-phase stepper motor specially designed for 3D printer extruders, CNC machines, robotics, and plotters. Despite its small 23mm body length, it delivers a strong 14N·cm (1.24 lb·in) holding torque, making it a powerful yet lightweight choice for precise motion control applications.

This Nema 17 17HS4023 stepper motor is widely used in 3D printer extruder systems to feed filament into the nozzle with accuracy and stability. The 1.8° step angle ensures smooth, precise movement without the need for encoders, offering high repeatability and easy integration with stepper motor drivers. Its low current draw (1.0A rated) and 12V operating voltage make it energy-efficient and suitable for compact and lightweight machine designs.

Perfect for mini desktop 3D printers, CNC routers, engraving machines, and automation projects, this motor provides excellent performance, low vibration, and consistent torque output. Built with durable materials and Class B insulation, it ensures long service life even under continuous use.
