Description
Introduction
The 17CS07A-180 is a two-phase Nema 17 stepper motor from Cloudray that has a step angle of 1.8°. Each phase draws 1.8 A at 3.49 V, which enables a holding torque of 71Ncm. The motor has four color-coded wires for the two coils.
You can find the same stepper motor with a connector instead of fixed wires here.
