Ruth's sister 40x40x11mm Aluminum Heatsink for 42 Stepper Motor internal power cable

SKU CH-6FMF-RG5CS

An aluminium heatsink sized 40 by 40 by 11 millimetres that draws heat away from a 42 stepper motor in 3D printers or CNC machines

  • Keeps 42 stepper motor cool with aluminium radiator
  • 40×40×11 mm profile fits tight printer frames
  • Single heatsink weighs little, installs in seconds
  • Aluminium construction resists corrosion in humid workshops
  • Direct contact draws heat away from motor windings

Aluminium heatsink for 42 stepper motor

This 40 by 40 by 11 millimetre aluminium heatsink is designed to draw heat away from a standard 42 stepper motor. It suits 3D printer and CNC machine operators who need to keep motor temperatures stable during long or heavy jobs. The part is sold new as a single unit.

Mounts directly on the motor frame

The heatsink fits onto the motor body without additional brackets or wiring, so it adds no electrical load to the system. By spreading thermal energy into its fins it frees the motor from throttling caused by heat build-up. No fan or active cooling is included in the package.

For builders running 42 stepper motors hot

Users who run 42 stepper motors at high current or for extended prints will benefit from the extra dissipation. The heatsink does not address electrical noise, driver overheating or mechanical vibration. Buyers needing active airflow or a larger thermal mass should look at alternative cooling solutions.

Questions about this item

At what temperature does the 40x40x11mm aluminum heatsink stop being effective for a 42 stepper motor?

The heatsink continuously draws heat away from the motor body; there is no fixed temperature limit where it ceases to function, but motor performance degrades as temperature rises, so keeping the motor cool maintains output.

Does the heatsink make any noise or need extra power when the printer runs all day?

It is a passive aluminum block with no fan or moving parts, so it adds no noise and draws no electrical power during continuous operation.

What mounting hardware or thermal interface do I need to attach this heatsink to my 42 stepper motor?

The package includes only the heatsink; you must supply your own thermal adhesive, thermal pads or mechanical clips to secure it to the motor housing.
