KST-28B18-0001 NEMA 11 28mm 5-Phase Stepper Motor – 0.72° Step Angle, 1.2A, 0.05N.m Torque

The KST-28B18-0001 is a compact and high-precision 5-phase stepper motor featuring a 28mm (NEMA 11) frame size and 0.72° step angle, ideal for applications that require fine positioning and smooth operation. With a rated current of 1.2A, it delivers 0.05N.m holding torque, ensuring reliable performance in space-constrained environments. The rotor's low inertia of 9 g·cm² allows for faster acceleration and deceleration, while the 5mm shaft diameter and 15mm shaft length ensure easy mechanical integration.

This motor is particularly suitable for medical devices, semiconductor equipment, camera systems, optical instruments, and other automation systems demanding precision and miniaturization. Its lightweight design (110g) and motor length of only 32.2mm make it an excellent choice for OEM solutions where compactness and accuracy are key.
