CC Blower....Blows

[What's_nitro?]

What motor is that??? It has longitudinal fins....that's why you had to cut the shroud. A CC motor has the fins around the circumference and that allows the air to escape freely.

It's a Hobbywing 2000kv but I also have 2 CC motors and it's the same effect with those. Restricted air flow is one of the problems with this unit, the other is fan size..too small for the task at hand. A 30x7mm fan might do fine on a 540 but not the 670s.

The 30x30 fan that George recommended is still holding find for me in my Truggy.

Lost a blade on the fan in my ESC on my buggy and I'm going to use the same fan to replace it when I get a chance.

Very cool! Or should I say supercool..LOL The ones I installed in both my MMMs are still running perfect, even in all this heat

I also replaced the fan in my mmm with the fan listed above. Haven't done much with the car lately so no real testing.. thanks for the info..

I don't understand why the blower's made of plastic. Plastic is an insulator and will retain heat, why not have it made of aluminium so it can serve as another heatsink?

Because it doesn't make enough difference to justify the expense. We tried an aluminum shroud, but it didn't conduct much additional heat from the motor.

The fins built into the motor are pretty effective as a heat sink. The shroud is there to direct the airflow so it all goes over the fins.

I run one on my HV 4.5 in a hyper 10sc geared for 40mph...I ran 6 2s 30C 5200mah packs through it back to back to back etc etc...and the hottest thin on the car was the lipo at 110....the mmp was 120ish...the 4.5 was consistently 110 but 120 aroung the solder tabs...so the shroud is doing it's job IMHO ....before the shroud I would have to gear down on the motor BC 40mph gearing made the motor 155 consistently (pre-shroud)

Just thought I'd share what I came up with for fan mount for my Flux motor.

It is made so that it is keyed and fits tightly between the heat sinks on the motor. I have to lightly tap it (slide from the front) with a hammer to get into place.

Test ran it at a race last night, and it didn't move at all. Very happy with how it turned out. Motor temps were great too. I made some other changes that helped with motor temps, but I know the fan is helping too.

Thanks Patrick. Posted just incase someone was struggling like I was with how to mount a fan on this motor. Not sure there is a market for them, but feel free to use the idea if you want to make a fan mount for the Flux motor.
