KST-42B30-D-0002 NEMA 17 5-Phase Stepper Motor – 0.72° Step Angle, 0.75A, 0.24N·m Torque, 42mm Frame

The KST-42B30-D-0002 is a high-precision 5-phase stepper motor featuring a 42mm frame size (NEMA 17) and a 0.72° step angle for fine-resolution motion control. Designed for applications requiring both accuracy and moderate torque, this motor is ideal for CNC machines, semiconductor equipment, medical devices, and 3D printers.

With a rated current of 0.75A, it delivers a holding torque of 0.24N·m and a rotor inertia of 68 g·cm², enabling stable performance under load. The 5mm shaft diameter, 20mm axis length, and 48mm motor body length make it easy to install in space-constrained environments. At 360g, it balances power and compactness, making it a reliable choice for precision motion applications.
