Re: 2.5" CIM Motor stops when climbing

Alternatively you could buy this 16:1 BaneBots Gearbox from AndyMark that comes with all the parts you need (though costs more). You could also use a ToughBox Micro with a 12.75:1 ratio and add a sprocket reduction using a 12 tooth and a 15 tooth sprocket. I believe both Vex and AndyMark ship internationally.

If you want to continue to use your current setup, it shouldn't be too difficult to integrate a Versa Planetary into it as it has the same mounting holes as the CIM ( you'd would probably need to use a different sprocket). You might not have enough time to get it done before Bag day, but I'm sure there would be plenty of teams who would be happy to help you get it working at the NYC regional. |

Re: 2.5" CIM Motor stops when climbing
Just realized you guys will be at the nyc regional. I'll be there all 3 days without too much to do so if you need me to I an bring some versaplanetary parts and I can help you guys get running.

Do you have someone local (a physics teacher, perhaps) who can help you with the math? |

Re: 2.5" CIM Motor stops when climbing

I was responding to someone from Turkey who appeared to have neither an engineering background nor English as a first language. Assuming that, I tried to frame my response in simple terms. "Gearing up" is a phrase that typically refers to changing to a higher gear, either in a car or a bicycle, resulting in more speed and less hill-climbing ability. And, vice-versa. I did not think that a treatise on work per unit of time, torque or RPM was necessary - or helpful - in this instance. Similarly, given that the team is in Turkey, it might not be helpful for any of us to advise ordering this or that gearbox from AndyMark. (he asked, "Can we find another solution but using gearbox? On the motor side small gear, on the shaft side big gear possible?") Just sayin'. Last edited by chapman1 : 08-02-2017 at 11:47. |

Re: 2.5" CIM Motor stops when climbing
I understand you were trying to help, and I applaud that.
But I guess we'll just have to agree to disagree whether it is clearer or more confusing... especially for other students reading this thread who are just beginning to understand the concepts of torque and power and gearing. No treatise is necessary. Maybe just a footnote. |
