Re: pic: How we cool our compressor
This is not a joke this is really the configuration of our compressor.

Re: pic: How we cool our compressor
Wow, that looks "cool" lol. quick question, today after my team was doing some neat re-wiring our compressor would not go on, after rigorous checking with the multimeter, the pwm cable leading to the compressor practacly exploaded, and the black cable was the only one that melted like crazy, do you think it happend because of how hot the compressor gets, or of some other reason.

Re: pic: How we cool our compressor
Thanks for the cool comment, lol. The first thing i would say is that the compressor should be hooked up with at least 18 guage wire, i used 14 to wire our compressor. Also electricity is the flow of electrons, which are negatively charged. They flow from positive to negative, and since the black wire is the negative thats why it melts. Also if you wire your compressor and it doesn't turn on but just melts the wire then you probably have a bad compressor or something has jammed in the motor causing the charge to build up and melt the wire. If you have more questions im me at etakto738

We were so glad that we had not fried the RC nor anything else for that matter. |

Make sure all cables and power leads are hooked up correctly polarity wise, and when they are right, make sure they're tight! It'll save you alot of headaches later. |

Re: pic: How we cool our compressor
to be honest with you....that is really not necessary. The compresssor is built to perform.....so it is inevitably going to get hot...but it is supposed to do that. We run our test board with the compressor and we push that little thing pretty hard, it gets so hot you cant touch the top but its fine. And the match is very short, only a few minutes, so the compressor will only be on a max time of the match time, which is pretty brief, but still very demanding of the compressor. If weight is an issue for you guys, i would consider removing that.

On a side note (in the past) COTS fans have been considered motors and are illegal. I looked around the Q&A and didn't find anything, so you might be okay, but don't be surprised if you fail inspection at your event(s) and have to remove it. If your compressor gets too hot to the point of where you need a heatsink after running it for 2 minutes (or less) then something is probably wrong with your compressor. Our pneumatics demonstration board has ran for several hours straight before when the programmers were working with it .. and the compressor got warm/semi hot to the touch, but nothing worth being concerned over, and nothing that could cause any burns or raise any safety concerns (although common sense is a different story) JMHO :) |
Re: pic: How we cool our compressor
if the compressor is running in reverse, it will still work but not as well and it will get very hot very quickly. you might want to check that it is running the right way.

Re: pic: How we cool our compressor
Since I didn't want to start a new thread, I thought I would go off of this one since it seems to be pretty relevant to my question.
Can a compressor burn out? I know that all of ours will get very hot with extended use. I want to know because we are rebuilding our T-Shirt Shooter robot. We are going to use 3 compressors to reduce the stress on the compressors and to speed up the fill time. Back to my original question though, can a compressor get so hot that it ruins the gaskets inside the compressor? Also as a side note for any other teams that look at this. I took apart the compressor yesterday just to check things out (this is our 2004 compressor and it is missing a bolt in the back and a bolt in the panel on the front. The front panel isn't air sealed at all, it's just a sound dampener. If you take the front panel off, you will see the piston and the motor output. Theoretically it shouldn't matter if you run the compressor in reverse, it should heat up in the same time. Also for the motor, there is no diode to control the flow of current. The "Thermal Protection" is just for the motor and not for the compressor itself. The "Thermal Protection" is a circuit breaker inside the compressor that trips if the current exceeds it's limit (I'm not sure what that limit is though) I have a way to attach a thermistor to the top of the compressor to detect the temperature, but it wouldn't be legal in competition because I took out one of the top screws on the compressor and torqued it back down, so it would be modifying. The thermistor seems to be fairly accurate and shuts the compressor down at the same temperature as it's programmed to do. The only reason I asked if it can burn out is because this adds a lot of complexity to the system with programming, visual alerts to the OI, and then the custom circuitry (the circuitry is the easiest part though :D). But please help me. |
