35 N·m Stepper Motor With Brake - NEMA 52 closed loop Heavy Load

35 N·m Stepper Motor With Brake for Heavy-Duty Positioning

The 130J12225EC-17BC-SC is a 35 N·m Stepper Motor With Brake in a NEMA 52 frame, delivering 35 N·m holding torque from a 225 mm body at 6.8 A per phase on a 24 mm shaft. It is among the largest motors in the closed loop stepper catalog and is intended for axes that carry substantial mass.

Integrated Brake Function

The integrated brake holds the load when power is removed, which is critical for vertical axes and rotary tables where gravity or process forces would otherwise move the load. The brake engages automatically on power loss, converting the motor from a positioning device into a static support.

High-Resolution Feedback

Position feedback is provided by an integrated 17-bit encoder. The high resolution allows smooth low-speed motion and precise final positioning, while the closed loop detects and corrects any deviation from the commanded path.

Application Fit

CNC machine tools, heavy factory automation, and precision robotic mechanisms are the natural territory for this 35 N·m Stepper Motor With Brake. The brake removes the need for separate mechanical locks on vertical axes, simplifying the machine design and improving safety during power interruptions. Lyenwsin offers this motor with a matched drive and brake wiring support.

Brake System Planning

Confirm the brake release voltage and the timing sequence in your controller so the axis is unlocked before motion begins. On heavy vertical axes, size the brake holding capacity against the static load plus a safety factor. Our team can provide the wiring diagram and the recommended release-current settings for your drive family. A separate brake supply is recommended so the brake releases even if the main DC bus is de-energized during an emergency stop.
