Stepper Motor – NEMA17 –


SKU: ROB-139 - Mfg Part Number: 17HS8401


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 specific NEMA 17 Stepper Motor offers 73 of torque and 200 steps per revolution. Additionally, the motor has a handy JST connector, meaning the included 1000mm wires can be disconnected directly from the motor.
