KH MOTOR 42BYGH101-1-15 / KH 2017 04 NEMA Stepper Motor

KH MOTOR 42BYGH101-1-15 / KH 2017 04 Stepper Motor

The KH MOTOR 42BYGH101-1-15 is a NEMA 17 hybrid stepper motor designed for applications requiring precise, repeatable, electronically controlled positioning. With a 1.8° step angle, it provides 200 full steps per revolution. When paired with a compatible driver, it can also operate in microstepping mode for smoother and more accurate motion.

This motor is ideal for automated systems, light-duty CNC machines, 3D printers, robotics, and linear motion mechanisms. The 42BYGH101 series is generally built with a 42 mm square frame and an approximately 40 mm motor body length. Available series specifications indicate a nominal voltage of around 2.5 V, a current rating of 1.7 A per phase, approximately 1.5 Ω phase resistance, and a holding torque close to 0.35 N·m.
