7.8 N·m Brake Closed Loop Stepper - NEMA 34 with Holding Brake

7.8 N·m Brake Closed Loop Stepper with a NEMA 34 Frame

The 86J12156EC-1000-60-SCG is a 7.8 N·m Brake Closed Loop Stepper providing 7.8 N·m holding torque in a 156 mm body at 3.0 A per phase on a 14 mm shaft, with 1,000 P/R feedback.

Recoverable, Not Lost Steps

Because the drive sees actual rotor position from the 1,000 P/R encoder, it can detect the moment a load spike pushes the motor toward stall and correct for it. This converts what would be a lost-step event in an open-loop system into a recoverable transient.

Brake for Compact Axes

The integrated brake holds the axis when power is removed, so vertical segments in packaging or handling systems stay fixed. It also supports safe stop behavior on lines that cycle frequently.

Specifications

• Motor type: 3-phase hybrid stepper, closed loop, with brake
• Frame size: NEMA 34
• Body length: 156 mm
• Phase current: 3.0 A
• Holding torque: 7.8 N·m
• Shaft diameter: 14 mm
• Feedback: integrated 1,000 P/R encoder

Applications

Packaging machinery, textile lines, and automated handling systems are the core fit. The motor also appears in factory automation cells where compact size and closed loop reliability are equally weighted. Lyenwsin supplies this 7.8 N·m Brake Closed Loop Stepper with compatible drives and brake wiring support.

Line Integration

Program the brake release to follow the drive enable so restart is smooth after a line stop. On vertical conveyor segments, verify the brake holding force exceeds the load under worst-case conditions. The 3.0 A rating allows this brake motor to share a drive cabinet with other NEMA 34 closed loop axes. If the line has frequent power dips, a small brake supply capacitor can hold the release signal long enough for a controlled stop. For packaging lines that cycle frequently, this 7.8 N·m Brake Closed Loop Stepper keeps registration repeatable between every cycle.
