The 110J18115-460 is a NEMA42 Stepper Motor, the shortest 110 mm-frame motor in this range at 115 mm, delivering 12 N·m of holding torque at 6.0 A through a 19 mm shaft. It is a 2-phase stepper that provides open-loop control for axes that need the NEMA42 mounting and shaft standard with a more compact body.
Twelve N·m is still a substantial figure for a two-phase stepper, adequate for medium rotary tables, indexing fixtures and CNC axis drives that must hold position against moderate loads. The reduced length trades a portion of torque for a smaller footprint.
For a rotary table divided into indexed positions, the holding torque resists angular creep while the part is stationary. For a CNC axis, the motor provides positioning authority within the limits of an open-loop system, where the application must not demand feedback-based compensation. It also suits heavier robotic mechanisms and large indexing conveyors where the 110 mm frame is already specified.
Standard NEMA42 bolt geometry simplifies retrofit into existing frames. The 6.0 A rating aligns with commercial NEMA34 and NEMA42-class drivers, reducing supply-chain constraints. Because the motor is shorter than long-body NEMA42 units, check that the coupling pocket and rear motor cavity still leave clearance for wiring and air circulation.
A precise rotor-to-stator air gap lowers heating and mechanical vibration, supporting consistent step accuracy across repeated cycles in production equipment. When selecting a drive, confirm it can supply continuous 6.0 A to keep torque available under sustained indexing duty. Lyenwsin can supply this motor with a matched drive and support for the full axis.
