S Series Nema 34 Closed Loop Stepper Motor 8.0Nm(1132.89oz.in) with 7.0Nm(991.28oz.in) Electromagnetic Brake

This is a S series Nema 34 closed loop stepper motor with a holding torque of 8.0Nm(1132.89oz.in) and rated current of 6.0A. Enquipped with a 1000ppr optical incremental encoder and a 24V 7.0Nm(991.28oz.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.
