35 N·m 3-Phase Stepper Motor with NEMA52 Frame

The 130J12252-368 is a 3-phase stepper motor on a NEMA52 frame with a 252 mm body length. It produces a 35 N·m holding torque, draws 6.8 A per phase, and turns a 19 mm output shaft. Operated in open-loop positioning, it gives repeatable step-indexed motion for machines with sizable but not extreme axis loads.

Torque and Frame Considerations

A NEMA52 frame with a 252 mm stack provides the rotor volume for a 35 N·m holding rating. As with all steppers, usable torque decreases as speed rises; sizing must leave the axis's running-torque duty inside the speed-torque envelope. The shorter stack relative to the 280 mm variant of the series trades torque for a slightly more compact body while keeping the same frame class.

Open-Loop Precision and Quiet Operation

High-precision stator and rotor geometry with small air gaps promotes consistent torque per step and low vibration, which helps keep open-loop movements smooth and position predictable. Constructed from high-quality materials, the motor is engineered to run with lower heating, supporting acceptable continuous duty within its thermal limits.

Electrical and Mechanical Outline

A 6.8 A phase current energizes the windings to their rated field for full torque output. The 19 mm shaft gives a rigid interface for direct, belt, or gear coupling, and the compact 252 mm body eases fit inside space-limited machine frames while preserving high load capability.
