S Series Nema 23 Closed Loop Stepper Motor 1.2Nm(169.97oz.in) with 2.8Nm(396.51oz.in) Electromagnetic Brake

This is a S series Nema 23 closed loop stepper motor with a holding torque of 1.2Nm(169.97oz.in) and rated current of 4.0A. Enquipped with a 1000ppr optical incremental encoder and a 24V 2.8Nm(396.51oz.in) electromagnetic brake, it combines the precision and reliability of closed-loop control with the safety and energy efficiency of a power-off brake. It is primarily used in automated equipment such as vertical axes and robots that require power-off locking and precise positioning.
