Stepper Motor - NEMA-23 Size with 9mm GT2 Pulley - 140 oz/in 2.8A

Product ID: 5117


These NEMA-23 Size Stepper Motors come to us from X-Carve, they're used by folks to make CNC machines so they're very strong, fast and reliable. In the X-Carve, these run the three axes on their routing machine and have pulleys pre-attached (see datasheet for the pulley specification). For wiring, there's a snap-in wiring harness

This 4-wire bipolar stepper has 1.8° per step for smooth motion and nice holding torque. The motor was specified to have a max current of 2.8A  so if you have a stepper driver with current limiting, set the max to 2.8A (or less). You can use our DRV8833 driver chip with this stepper, it's limited at 1A so you wont get the max torque. Or you can go with a real CNC driver board like the gShield or tinyG CNC controller for multiple stepper control!
