The 110J12220-360 is a three-phase open-loop stepper motor producing 22 N.m of holding torque at a 6.0 A phase current. It fits the NEMA42 frame, a common size for CNC and industrial axis loads that need more torque than a NEMA34 but do not require full servomotor closed-loop control.
Three-phase operation lowers torque ripple, and the 6.0 A winding is wound to keep resistive heating in check. This matters when the axis holds position under load for long periods, as lower temperature rise preserves both torque repeatability and bearing life.
The 19 mm shaft delivers torque through standard couplings. The NEMA42 flange gives a rigid, repeatable mount. Open-loop control means the drive issues step and direction pulses directly, so no feedback loop or tuning is needed.
Its torque and frame size fit Compact CNC Equipment, Packaging Machinery, Factory Automation, Compact Robotic Mechanisms, Textile Machinery, Printing Machinery, and Food Processing.
Pair the motor with a 3-phase stepper drive rated for at least 6.0 A output. The deterministic open-loop response makes it straightforward to tune cycle times, and low vibration suits machinery where smooth output affects product quality. Heavy load CNC axis and rotary table indexing work rely on its 22 N.m holding torque.
