28 N·m Stepper Motor With Brake - NEMA 52 with 17-bit Feedback

28 N·m Stepper Motor With Brake in a Space-Saving NEMA 52 Body

The 130J12205EC-17BC-SC is a 28 N·m Stepper Motor With Brake rated at 28 N·m holding torque in a 205 mm body at 6.8 A per phase on a 24 mm shaft. It offers most of the torque of the 225 mm variant while leaving more space for coupling and mounting hardware.

Locked When De-Energized

The built-in brake engages when power is removed, so a vertical spindle or a heavy rotary load cannot drop or drift after a stop command or an emergency stop. This makes the motor a practical choice for axes that must remain position-locked without continuous energization.

Encoder and closed loop Control

An integrated 17-bit encoder reports rotor position to the drive. Because the control loop sees actual position, the system can recover from momentary overloads rather than accumulating step loss, and torque output can be managed against the measured load.

Specifications

Target Applications

Rotary indexers, textile machinery, and automated handling mechanisms benefit from the combination of brake and closed loop feedback. This 28 N·m Stepper Motor With Brake is also well matched to CNC axes that need fail-safe behavior during a power outage. Lyenwsin provides this motor with compatible drives and brake interface guidance.

Installation Tips

Mount the motor on a rigid plate so the brake reaction torque is fully supported, and leave clearance for the brake connector. During first power-up, test the brake release without load before commissioning the axis. The shorter body simplifies alignment of the coupling and reduces overhung weight on the machine frame. Check the 24 mm shaft keyway and thread depth against your coupling hardware before final assembly.
