This Nema 23 closed-loop stepper motor delivers a holding torque of 1.20Nm(169.93oz.in) and features a compact magnetic incremental encoder with 3-channel output and 1000ppr(4000cpr) resolution. Compared to other closed-loop stepper motors of the same size, this motor delivers higher output torque, making it ideal for applications requiring precision positioning control in space-constrained yet high-torque scenarios, such as collaborative robots, medical equipment, rail transit, and aerospace systems.
