This is a Nema 17 closed-loop stepper motor with a 1000ppr(4000cpr) incremental optical encoder, a rated current of 2.0A, and a holding torque of 52Ncm(73.64oz.in). Compared with open-loop stepper motors, it has higher precision, higher torque, less motor heat, lower power consumption, and better response to external factors.
