Vastly improve the thermal management and power handling of hub motors with ~200% better overall thermal dissipation allowing much higher power levels or endurance to be achieved. Much better Thermal Dissipation & Performance in combination with Ferrofluid. Thermal Paste is included.

HubSink will fit any of the ‘standard’ hubs with a 222mm ØD Magnet ring and at least 18mm free space between spoke flanges, like MXUS, QS 205, Leaf, Crystalyte, 9C (as a side note, thinner hubs like the 29mm stator MXUS will see a higher increase in thermal dissipation as a relative value).

We designed the HubSink in 6 pieces so even on a 17” moto rim with 10a spokes, they should be easy to slide in then install.

Black anodisation will improve the emissivity factor from approx 0.09 to 0.89, so we did.

Turbulent flow has a much higher rate of heat transfer than laminar, combined with the centrifugal action of the fins we have found this design to be the most effective.



STEP 1 - Clean the outer magnet ring surface of all dirt and oils before applying the thermal paste or tape, don't use any petroleum based cleaners (WD-40, and many automotive degreasers) This oil, which is engineered to not evaporate, will fill the microscopic valleys in the metal and significantly reduce the effectiveness of any subsequently applied thermal compound.
Keep the surface free of foreign materials and do NOT touch the surface after it has been cleaned. A hair, piece of lint, and even dead skin cells can significantly affect the thermal interface's performance. Oils from you fingers can adversely affect the performance by preventing the micronized silver or ceramic fill from directly contacting the metal surfaces. (Fingerprints can be as thick as 0.005”)

Step 2 – Test fit the HubSinks around the Hub with the included mounting nuts and bolts, ensuring the fit is snug and no movement is noticeable, if they don't bolt up tight due to difference in motor tolerances, sand or linish 1mm off the mounting tabs on each sink until they tighten snugly around the hub. Once the HubSinks fit snugly, remove and proceed to step 3

Step 3 – Apply the thermal paste generously to the hubsink piece (we want to use the entire 5G tube across the 6 peices) insert the coated piece between spokes and push down firmly, give the piece a slight twist to ensure the thermal paste has coated the entire connection, continue around the hub in the same manner then tighten down.

Step 4 – Turn the amps up and go for a ride, try to get the hub as hot as possible on the first ride to get the thermal paste to seat correctly and efficiently, re-tighten the hub and ensure its all fitted well, performance will increase over the first few rides as the paste fills all the microscopic gaps.

Step 5 – Enjoy

Customer evaluation for "HubSink V2 Improved Thermal Dissipation for Hub Motors"

HubSink V2 ist genial !!!

Ich empfehle den HubSink V2 jedem , der mehr Leistung aus dem Motor rauspressen will !!! Ich fahre den MXUS 3K-Turbo 4T , befüllt mit Statorade Ferrofluid bei 8KW Leistung . Beim häufiger Beschleunigung oder bei hoher , dauerhafter Geschwindigkeit wurde der Motor nach einiger Zeit zu heiß . Das ist aber keine Überraschung , weil dieser Motor nur für 3KW ausgelegt ist . Aus diesem Grund habe ich den HubSink V2 bei FASTERBIKES bestellt und das war eine super Entscheidung . Jetzt dauert es deutlich länger bis die Temperatur im Motor steigt und sie sinkt auch schneller . Die Temperatur im Motor ist jetzt im Durchschnitt mindestens 20° Celsius niedriger als bei der gleiche Fahrweisen ohne den HubSink V2 . Der Motor ist meiner Erfahrung nach auch etwas effizienter geworden , weil er nicht so heiß wird . Bei der Installation empfehle ich , es mit zwei Personen zu schrauben . Der eine hält fest und der Andere Schraubt ruhig . HubSink V2 ist sein Geld wert . Jetzt kann ich noch mehr spaß haben , ohne , dass ich ständig auf die Temperatur Anzeigen schauen muss .

Great thing
