    Motor cooling

    Anyone have any luck with running just a small cooling fan on the back of there vented motors { NEU} for cooling rather than useing water coolers?

    I have though of doing it with the 12v fans from radio shack, but havent done it yet, using jackets. Seems like it could work, since the Neu's are so efficient to start with and you would constantly be vacating the heated air from the motor. Just remember though, in an enclosed hull the air would also heat up as the run increases, thus decreasing the cooling of the motor to some degree.
    NEED PARALLEL CONNECTORS?? QUALITY 5.5MM, 8MM, 8 AND 10 AWG, GET THEM HERE: http://forums.offshoreelectrics.com/...est!&highlight=

      I've had good luck with them on my monos and cats. Depending on what power I'm running, sometimes I have to use a UBEC to power the fan because pack voltage is too much (6S/8S). I have 5v fans and 12v. I know Jay is a fan (pun intended) too as well as others. Its been well proven as a viable cooling system.

      The fact that the Neu motors have open end bell lends itself to this type of cooling method. And its very effective. You cool both the rotor and the windings. Unlike shell (case) cooling or motor mount cooling where all you do is cool the outside of a motor. If you were going to build boats with 10 or 20 minute run times then a fan would probably not be a good choice but with our 3 to 5 minute runs? Theres enough air in most mid size boats to make fan cooling a serious, yet so simple, contender to get the job done.

          Here is one of my setups with a 40mm 12v fan and 4S/800 mAh power. The switch lets me turn the fan on before I tape up.

            Dual cooling Neu motor

            I have used a fan to air cool a multilayer esc and dual cooled the Neu motor with water and air.

              Something I vac pulled...a little tweaking but pulls air thru the motor not just blow on it.

                Anyone know how much air volume is squeezed through the windings and rotor gap in CFM??
