Nema34 stepper motor delivers 12.00 N.m torque at 6.0 A for CNC axes

  • High torque 12.00 N.M drives demanding CNC axes
  • Nema 34 frame fits standard 86 mm mounting pattern
  • Two-phase four-lead design simplifies driver wiring
  • Low-noise operation keeps workshop volume down

High-torque Nema34 stepper motor

This Nema34 stepper motor delivers 12.00 N.m of holding torque for CNC XYZ axes and similar motion-control builds. It uses a two-phase, four-lead winding rated at 6.0 A per phase and has a body length of 159 mm. The 86BYGH5401 model suits integrators who need strong positioning force in a standard frame size. Builders requiring a different frame size or lower current draw should look elsewhere.

Low-noise thermal profile

The motor is specified as low noise, which typically means reduced acoustic output during high-speed stepping. Rated current of 6.0 A determines the driver heating and power-supply load in normal operation. Torque of 12.00 N.m is produced within the thermal limits of the 159 mm body. No active cooling method or thermal resistance figure is provided in the data.

Questions about this item

How do I wire the 4-lead Nema34 stepper motor to my CNC driver, and which step do builders often miss?

Connect the two phase pairs to the driver terminals matching the 2-phase 4-lead layout, then set the driver current to 6.0 A; the step most skip is verifying the motor’s 12.00 N·m torque rating against the driver’s peak current capability before first power-up.

What maintenance will the 86BYGH5401 stepper motor need after extended CNC use?

Periodically check the shaft bearings for play and listen for increased noise; re-grease or replace the bearings if the 159 mm motor body runs hotter than normal or develops vibration, and ensure the 6.0 A current setting has not drifted.
