Stepper Motor – NEMA23 – 166


SKU: ROB-191 - Mfg Part Number: 57STH56


Stepper motors are great motors for position control. They can be found in desktop printers, plotters, 3d printers, CNC milling machines, and anything else requiring precise position control. Steppers are a special segment of brushless motors. They are purposely built for high-holding torque. This high-holding torque gives the user the ability to incrementally “step” to the next position. This results in a simple positioning system that doesn’t require an encoder. This makes stepper motor controllers very simple to build and use.

This large NEMA 23 Stepper Motor offers a massive 166 of torque, making them suitable for higher loads than their smaller NEMA 17 counterparts. The motor has 200 steps per revolution and features 50 cm leads.
