NEMA17 JK42HS48 Stepper Motor, 5.5 kg-cm, D-Shaft

Description

This NEMA17 stepper motor (model JK42HS48-1684-03F) is engineered to deliver reliable and precise motion control, making it an essential component for various digital fabrication and automation projects. With a robust 5.5 kg-cm holding torque at 1.5A current per phase, it ensures consistent power and accuracy for demanding tasks. The motor’s inherent precision, achieved through a 1.8° step angle, is particularly beneficial in applications where fine positional adjustments are critical, such as 3D printer axes, small-scale CNC machines, and robotics.

The motor’s shaft features a D-type machining, specifically designed to enhance grip with attached components like pulleys or drive gears. This design significantly reduces the risk of stalls or slips, ensuring that the motor’s motion is accurately transferred without loss of steps. Control of this motor is streamlined by a simple open-loop mechanism, negating the need for complex electronic control circuitry and offering a cost-effective solution for motion systems requiring accuracy at lower speeds.
