I got my motor from this thread, but that was a year agoBadkad wrote:Where can I get that Z-force motor from?
Can't do that because motor has opening around encoder in one side and opening in the edges in sprocket side. So rotor itself using tsentrifugal force will push air from encoder side to sprocket side.amberwolf wrote:As an experiment you might try flipping the fans and expanding the duct so that they suck the air thru the motor instead of trying to force it in.
Or use a single larger fan shaped just like those but with it's intake the size of the outlet ring on the motor, and place it directly against that outlet ring (or spaced a short distance away with a ring between them).
When I did acceleration test last year I had old hard tires and outside was 11 degrees.Hillhater wrote:Very impressive 0-100 run.....mainly because i dont figure how you got enough grip.
Every kart i have used (regular 2t race karts) have always had more power than grip..even with good warm tyres.?
Yeah, I know this, but this is 4WD and not comparable to kart. They also have suspensions and bigger tires (wider and bigger in diameter)Hillhater wrote:Also , depending on your definition od a "kart" , im sure you are aware of the 1.51 sec time from this...
Thats the issue...Once you diverge from the common FIM/CIK specification a "Kart" , (motors, chassis, wheels , tyres etc) then you are in an "unregulated" area and as such there is no restrictions on what you use or what you call it.nuxland wrote:[Yeah, I know this, but this is 4WD and not comparable to kart. ......Hillhater wrote:Also , depending on your definition od a "kart" , im sure you are aware of the 1.51 sec time from this...
I'm using two of these fans 09533GA-12Q-AA-00 and according to specs they provide good airflow against pressure.craigcalfee wrote:Your fan size seems too small. When we bench tested that motor, a lot of air pressure is generated. That fan doesn't look like it would add much velocity to it. And the ducting is not so good for laminar flow. But good progress! Looking forward to the next improvement!
