Ah, Glorious Motors...
These new motors are definitely some that I will not just hook a battery up directly to get a torque and vibration feel. Thank you so much for getting these in the kit, Joe. You are indeed a saint.
Oh, are we allowed to use the motors from previous years not included in the 2002 kit? I'm unclear on that point. |
No additional motors.
There are no motors on the additional hardware list, so we can only use the ones that came with the kit.
P.J. |
The motors are used to drive a gearbox, the output of which turns a nut which makes a screw go up or down.
As to whether these motors are mainly torque or speed, of course, they are both. These motors are powerful. That means that the product of speed and torque is a high number (peaking at about 300W). Compared to many motors these motors are fast and not very torquey compared to many others they are slow and torquey. For a FIRST motor they are about as torquey as an armature gets without a gear reduction. I think we will grow to love them. Joe J. |
Hi All,
We decided to have our kit shipped to us this year and since we are in Hawaii, 2nd day air usually takes an extra day or two. The new motor sounds really great. Could someone who has received their kit please describe to me the gear that they included to mate to this motor? I believe Joe mentioned that the motor itself had 9 teeth and that the mating gear had 44 teeth. From what I understand, this 44 tooth gear also has a 32 DP gear attached to it. How many teeth does that gear have? Also, what's the diameter of the motor shaft? Does anyone think its reasonable to pull the 9 tooth pinion gear off of the motor and replace it with something more common? I'm starting to regret that we didn't pick up our kit at the remote kickoff! |
I Believe the mating gear is 44 tooth, 36 DP, with an attathed 16 tooth, 32 DP probably with a 20 deg. pressure angle gear.
Hope this helps. |

It is made of bronze
The gear appears to be made of some type of bronze. It is a gear 'cluster' with the 44 tooth and 16 tooth gears next to each other, and has a 1/4 inch hole through it.

Marc and Kit,
Thanks for your reply! At least our team can start thinking how we might use the new motors! Alan |
what about dimension
does anyone have the scematics for the chipewa motor
I am mostly looking for the radius for the center of the gear out thanks dahl home of the chalupa |
Solid Model of Chiaphua
I sent several file formats of the Chiaphua motor solid model to Ed Sparks. After he reviews it, he will most likely post it on his web page. I created it in SolidWorks, but saved to several other formats.

Oh, that's what the 2 brass gears in the bearing bag are for...
Boy, we were having a heck of a time trying to determine what the brass double-gears in our bearing bag were for. That sure clears that up. Now if they had put them with the Chiphwa motors, where they belong, it would have been clear. It's all so clear now that the brainfog has been lifted...

Using Chiaphua motors for high torque?
Hi,
As a part of rookie team, those new black motors certainly have appeal but I have no idea how to implement a drive train with them. Is there anyone out there who can give us an idea of how to use them for a two-wheel drive high torque configuration for pulling goals? |
