The 110J12161-360 is a 12 N·m 3-Phase Stepper Motor in a NEMA42 frame, rated at 12 N·m of holding torque at 6.0 A. Its 161 mm length is the short-body option in this line, fitting axes where axial space is the limiting factor more than torque. It is a practical choice for robotics and compact automation where an open-loop axis with modest torque is sufficient.
The short body frees panel and machine space while retaining the NEMA42 mounting interface. Open-loop operation keeps the system simple: the drive issues step and direction pulses, and the axis position is a direct function of the commanded steps.
Because it runs open-loop, the axis position is a direct function of the steps commanded, with no dependence on tuning gains or encoder scaling. Three-phase winding keeps the running smooth and the motor quiet, and heat rise stays low enough to sustain long dwell positions.
The 19 mm shaft couples to the load directly or through a belt. The NEMA42 flange offers a stable mounting interface. This is a practical choice where a machine already has a 3-phase stepper drive at 6.0 A and only needs an axis motor change.
It is sized well for compact CNC equipment, packaging machinery, factory automation, compact robotic mechanisms, textile machinery, printing machinery, and food processing. The short-body design is especially useful in robotic mechanisms and compact automation where axial space is tight.
Match it with a 3-phase drive output at or above 6.0 A. Open-loop control shortens setup, and the shorter body leaves more room for other axis components inside the machine frame. Lyenwsin offers drive pairing and mounting guidance to support your integration.
