110J18150-460 20 N·m NEMA42 Stepper Motor - 150 mm

Heavy-Duty 20 N·m NEMA42 Stepper Motor in a Shorter Body

The 110J18150-460 is a 20 N·m NEMA42 Stepper Motor on the NEMA42 (110 mm) frame, 150 mm long, with 20 N·m holding torque at 6.0 A. Its shorter stator stack compared with the 165 mm variant yields slightly less torque while retaining the full NEMA42 mounting interface and 19 mm shaft.

Heavy-Load Torque in a Shorter Body

At 20 N·m, this motor still moves heavy loads at low and moderate speeds, covering rotary table indexing, gantry positioning and ball-screw-driven CNC axes. The shorter body eases integration where machine depth behind the mounting face is limited.

Specifications

• Frame: NEMA42 (110 mm)
• Body length: 150 mm
• Phase current: 6.0 A
• Holding torque: 20 N·m
• Shaft: 19 mm
• Type: 2-phase, open-loop

Where the 20 N·m Rating Is Needed

On a CNC axis the motor holds position during static phases and delivers torque through the stroke without losing steps, provided the driver supplies rated current, which suits heavy workpiece feed axes. In rotary table service, standstill holding torque secures the table against off-center workpiece inertia during machining. Packaging and textile lines use it where a large-diameter roller or a heavy transfer mechanism demands torque that smaller NEMA frames cannot supply, and printing presses rely on its steady low-speed torque for registration of heavy reels.

Selection and Operating Notes

Match the driver to the 6.0 A phase current and size the axis on the torque-speed curve rather than the holding value alone, because torque falls as speed rises. Mount the 110 mm frame on a flat, heat-conducting surface; low motor heating extends the usable torque envelope across continuous production shifts. Verify the 19 mm shaft keyway and coupling rating handle the applied load before commissioning.

Construction Quality

High-precision stator and rotor geometry with a small air gap reduces vibration and keeps running noise low, supporting dependable repeatable motion in packaged systems. Lyenwsin supplies the motor with matching drives and technical guidance for large-axis builds.
