86J18156-460 High Torque NEMA34 Stepper Motor - 12 N.m

The 86J18156-460 is a 2-phase stepper motor on the NEMA34 (86 mm) frame, 156 mm long, rated for 12 N·m holding torque at 6.0 A with a 16 mm shaft. It delivers torque normally associated with larger frames from a package sized for compact machine bays.

12 N·m in a NEMA34 Footprint

By producing 12 N·m from the 86 mm frame, this motor suits compact industrial automation where floor or cabinet space is limited yet the duty requires meaningful torque. The 16 mm shaft carries the torque with a coupling shoulder sized for robust transmission.

Engineering Specification

• Frame: NEMA34 (86 mm)
• Body length: 156 mm
• Phase current: 6.0 A
• Holding torque: 12 N·m
• Shaft: 16 mm
• Type: 2-phase, open-loop

Fit for Packaging and Textile Machinery

Packaging lines value holding torque for intermittent indexing of transport and infeed mechanisms; textile machinery requires smooth, low-vibration motion to maintain registration. This motor addresses both: sufficient standstill torque plus minimal vibration from a precisely gapped rotor-stator assembly.

Thermal Behavior

Low motor heating preserves rated torque through sustained cycling, which is relevant where packing cells run at high duty factor.

Open-Loop Control Logic

As an open-loop stepper, it accepts step/direction commands directly, simplifying the control path in established machine designs and avoiding the added wiring of a closed-loop system.
