Product Positioning

The 110J12190EC-1000 is a 3-phase closed-loop stepper motor in a NEMA 42 frame. Its 190 mm body length and 20 N·m holding torque place it at the high-torque end of the NEMA 42 range, a size class normally reserved for machines where load margin is the primary design constraint.

Closed-Loop Feedback and Missed-Step Control

How Position Is Verified

An integrated 1,000 P/R encoder closes the position loop. Where an open-loop stepper can lose steps when the load exceeds torque capacity, the drive here compares commanded and actual rotor position continuously, so transient overloads are corrected rather than accumulated.

The benefit is most visible in applications with variable friction or rapid acceleration profiles, where tuning an open-loop system becomes a compromise between stability and throughput.

Thermal and Torque Behavior

At 6.8 A phase current the motor develops its rated 20 N·m holding torque. Operating temperature is a function of duty cycle, ambient conditions, and mounting surface; adequate air circulation or a cooling plate is recommended when the axis runs at high duty for extended periods.

Specifications

  • Motor type: 3-phase hybrid stepper, closed-loop
  • Frame size: NEMA 42
  • Body length: 190 mm
  • Phase current: 6.8 A
  • Holding torque: 20 N·m

Application Guidance

Typical installations include CNC machine tool axes, rotary tables, and automated handling mechanisms where the combination of holding torque and closed-loop positioning avoids re-homing after a stall. It is equally suited to packaging and printing lines that run continuous production schedules. Heavy load CNC axis feeds and rotary table indexing stay accurate cycle after cycle.
