The 86J12126EC-17BC-SCG is a 6.8 N·m Stepper Motor With Brake with a 126 mm body, rated at 6.8 N·m holding torque and 4.0 A phase current on a 14 mm shaft. It is a compact, higher-current member of the NEMA 34 brake family.
An integrated 17-bit encoder closes the position loop. Unlike an open-loop stepper, the drive sees the rotor position and can compensate for load-induced error, so the axis maintains its commanded path even when friction varies.
The brake holds the rotor when power is removed, preventing a vertical axis from drifting or a mechanism from moving during setup. This is valuable in factory automation and robotic cells where personnel may work near the axis while it is stopped.
Packaging machinery, printing systems, and precision robotic mechanisms where a compact axis must hold position without continuous power. The motor is also used in food processing equipment that requires repeatable, drift-free indexing. Lyenwsin offers this 6.8 N·m Stepper Motor With Brake with compatible drives and wiring support.
Confirm the drive supplies the higher 4.0 A phase current and that the brake connector is routed with strain relief. During initial setup, test the brake while the machine is unloaded, then verify the holding force with the real payload. The short body suits Z-axis assemblies where vertical travel space is limited. Contact Lyenwsin for the encoder wiring diagram and the recommended drive parameters for the 17-bit feedback. This compact 6.8 N·m Stepper Motor With Brake is frequently selected for packaging stations where both precision and a positive stop are mandatory.
