Stepper Motors

Stepper motors divide a full rotation into discrete angular steps, enabling precise position control without a feedback encoder. Each step corresponds to a fixed angle, and the cumulative step count directly maps to angular position, making steppers ideal for open-loop motion control.

The range includes the NEMA 17 bipolar stepper widely used in 3D printers and CNC machines, the larger NEMA 23 for higher-torque applications, and the compact 28BYJ-48 unipolar stepper with integrated gearbox for low-cost Arduino projects requiring modest torque at reduced speeds.

Stepper motors are used in 3D printer X, Y, and Z axes, CNC router and laser cutter positioning, camera slider drives, telescope mounts, Arduino-controlled focus mechanisms, pick-and-place machines, and STEM projects demonstrating precision motion control.
