86J1880-460 Medium Torque NEMA34 Stepper Motor - 4.5 N·m

A Compact Medium Torque NEMA34 Stepper Motor at 4.5 N·m

The 86J1880-460 is a Medium Torque NEMA34 Stepper Motor, the shortest 6 A member of the series at 80 mm, producing 4.5 N·m with a 12.7 mm shaft. Its compact length suits machines with tight electrical and mechanical envelopes.

Torque Density in a Compact Package

At 4.5 N·m from an 80 mm body, the motor offers a high torque-to-length ratio for compact industrial automation. It is appropriate where a full-length NEMA34 motor cannot be accommodated but NEMA34 torque is still required.

Data

• Frame: NEMA34 (86 mm)
• Body length: 80 mm
• Phase current: 6.0 A
• Holding torque: 4.5 N·m
• Shaft: 12.7 mm
• Type: 2-phase, open-loop

Packaging, CNC and Gantry Positioning

Packaging cells, compact CNC axes and light gantry systems benefit from a motor that keeps a low profile while delivering steady torque. The reduced length also lowers rotor inertia, which can improve response for rapid, short moves. In CNC duty the compact body is easier to enclose, while gantry axes keep a slim profile over the travel length.

Vibration Control

Precise stator-rotor geometry with a small air gap keeps vibration low, supporting accurate registration in intermittent-motion machinery. Low vibration also reduces wear on couplings and leadscrew supports over the machine lifetime.

Retrofit Perspective

The 80 mm body is noticeably shorter than the 118 mm and 156 mm NEMA34 options, so it can replace a longer motor where space was previously the constraint. Because the frame, current and shaft family remain NEMA34-standard, the retrofit keeps existing drivers and mounting hardware in most cases.

System Design

Select a 6.0 A-capable driver and verify coupling fit on the 12.7 mm shaft. The NEMA34 interface keeps mounting uniform across the series, simplifying spares and interchangeability. Confirm the torque-speed curve at operating speed, since the short stack limits peak torque at higher RPM. Lyenwsin can supply this motor with a matched drive for space-constrained automation builds.
