35J1834-407 NEMA14 Stepper Motor - 0.11 N·m, 34 mm

The 35J1834-407 is a NEMA14 Stepper Motor in the 35 mm miniature frame, 34 mm long, rated 0.11 N·m at 0.7 A with a 5 mm shaft. It is built for the most space-constrained precision mechanisms, where the value lies in step repeatability and quiet micro-motion rather than sheer force.

Miniature Precision Actuation

The 0.11 N·m torque drives light optical registers, laboratory fixtures, and small adjustment axes. Its 0.7 A current keeps driver requirements low, and the standard 5 mm shaft connects to the common couplings used in micro-instrument hardware. Because the frame is only 35 mm, the motor fits high-density layouts where even a NEMA17 would dominate the design.

Specification

• Frame: NEMA14 (35 mm)
• Body length: 34 mm
• Phase current: 0.7 A
• Holding torque: 0.11 N·m
• Shaft: 5 mm
• Type: 2-phase, open-loop

Medical and Laboratory Fit

Small medical instruments and laboratory mechanisms gain precise, quiet micro-motion from the low-vibration construction. The precise stator-rotor air gap reduces resonance and noise, supporting stable measurement environments in optics and diagnostics. The motor’s small footprint preserves compact device layouts.

Where It Works Best

Typical roles include light optical registers, filter drives, calibration fixtures, and adjustment axes in analytical equipment. In each case, the motor delivers repeatable open-loop stepping without the complexity of feedback hardware.

Mounting and Integration

The standard NEMA14 interface with a 5 mm shaft suits high-density, small-footprint instrument applications. Confirm the available torque at your working speed, since 0.11 N·m is a static rating, and keep moved mass low to maintain clean step response. When laying out the axis, also consider the driver: at 0.7 A a compact driver board is sufficient, and microstepping can further smooth the low-speed motion for applications such as filter wheel alignment and probe indexing. The motor’s light rotor also helps it start and stop cleanly, avoiding overshoot on short positioning moves.
