12 N·m NEMA42 Closed Loop Stepper Motor - Compact 135 mm Frame

12 N·m NEMA42 Closed Loop Stepper Motor in a Compact Body

The 110J12135EC-1000 is a 12 N·m NEMA42 Closed Loop Stepper Motor with a 135 mm body length and 12 N·m holding torque at 4.5 A per phase on a 19 mm shaft. It targets installations that need the stiffness of a 110 mm frame but cannot accommodate the longer body lengths of the 160 mm and 190 mm siblings.

Continuous Rotor Verification

An integrated 1,000 P/R encoder supplies rotor feedback so the drive can detect and correct position error. In practice this means the motor handles momentary load spikes without producing permanent positional error, and the system recovers to the commanded position automatically.

Performance Characteristics

Phase current is 4.5 A, which keeps the power requirement moderate while retaining a high-torque output for the frame size. The motor runs with low noise and low vibration, and closed loop control gives a fast response to step commands. It is a sensible choice when the drive’s current limit is a design constraint.

Typical Applications

Packaging machinery, printing presses, and automated handling systems that require dependable indexing benefit from the compact envelope. CNC machine tools and factory automation cells use this motor where axis space is limited but frame stiffness is still required. For heavy-load handling, CNC axis feed motion, and rotary table indexing, the compact frame keeps positioning stiff and repeatable. Lyenwsin stocks this motor with matching drives and can help with sizing.

Space-Saving Advice

The shorter rotor lowers reflected inertia, which helps tuning on axes with low load inertia. Confirm the drive can deliver 4.5 A and that the encoder connector is compatible with your cable set. For packaging machines with frequent start-stop cycles, the low-vibration profile reduces wear on the coupling and bearing assembly.
