Model: NEMA11 Closed Loop Stepper Motor-JK28HSN(1.8 degree)
A NEMA 11 closed loop stepper motor is a compact, high-precision motor with a 1.1 x 1.1-inch (28 x 28 mm) faceplate size, designed to deliver excellent torque, stability, and responsiveness in tightly constrained applications. "Closed loop" refers to its ability to self-correct and optimize performance using feedback from an integrated encoder, unlike traditional open-loop stepper motors.
This type of motor ensures that every step is accurately executed, eliminating missed steps and enhancing reliability. The combination of compact form factor, high torque density, and real-time feedback makes it ideal for modern automation, medical devices, robotics, and precision manufacturing.
JKONGMOTOR Nema 11 stepper motor is a stepper motor with a 1.1 x 1.1 inch (28.0 x 28.0 mm) faceplate. Next smaller size is NEMA 08, next bigger size is NEMA 14.This micro motor is small enough to fit in the palm of your hand but still features 16.7 oz-in of holding torque. These NEMA 11 stepping motors for sale are perfect for small CNC machines, 3D printers, laboratory assistance, linear actuators, telescopes, pick and place machines, and prototyping machines. Dual shaft .187 inch (4.75mm).
