High Torque Stepper Motor With Brake - 28 N·m NEMA 42

High Torque Stepper Motor With Brake in a Manageable NEMA 42 Package

The 130J12205EC-2500-SC is a High Torque Stepper Motor With Brake in a NEMA 42 frame with 2,500 P/R feedback. Its 205 mm body produces 28 N·m holding torque at 6.8 A per phase on a 24 mm shaft, a high torque-to-length ratio that leaves space for couplings and guards on the axis.

Verified Rotor Position

The 2,500 P/R encoder reports rotor position to the drive, allowing the loop to correct any deviation before it becomes a positioning error. The closed loop also lets the motor hold torque efficiently at standstill, since the drive can reduce current once position is verified.

Integrated Brake

On power loss, the brake engages and holds the rotor. This is important for rotary tables and CNC axes where the load can otherwise rotate or sag, and it eliminates the need for a separate locking mechanism.

Where It Works

On a CNC machine tool the motor drives ball-screw axes carrying heavy workpieces, where the closed loop removes the step-loss risk of open-loop drives and the brake secures the axis when the machine stops. Rotary tables and indexing stations use the standstill holding torque to keep off-center loads locked during machining, while automated handling mechanisms rely on the brake to prevent drift when power is removed.

Selection and Operating Notes

Size the drive for the 6.8 A phase current and check the torque-speed curve at your operating speed. Confirm the brake release voltage and timing with the drive vendor, and verify the mounting dimensions match your axis.
