The idea behind Statorade is brilliant and simple. A direct drive hub motor generates heat internally at the stator, but this heat has no easy path to escape since it is surrounded by trapped air. It is possible to cool the motor with vent holes and active airflow from outside, but this exposes the motor to the elements. Alternately, filling the motor with oil will cool the stator windings quite well, but with significant increase in motor resistance from fluid drag and an enormous sealing challenge to keep the oil from leaking Statorade is a unique ferrofluid from Grin Technologies that is designed to increase dissipation heat from hub motors. This increases power output capabilities, efficiency, and longevity. This 10mL Syringe of Statorade ferrofluid is for use in cooling direct drive hub motors, with convenient Luer Lock plastic nozzle for injecting into holes as small as 2mm diameter. Approximately 5mL of this fluid injected into a hub motor will more than double the ease of heat flow from the stator of your motor to the motor shell without any noticeable increase in motor drag.
