Wiring 8+ Motors
So 870 is bagged and tagged, but in one of our cleanup meetings, one team member had a good idea. Without getting into specifics, we need to put on another motor. We traditionally shy away from pneumatics, and so we already have 8 motors running, 4 CIMS, 2 Van Doors, and 2 Fisher Price. Most likely, we'd be adding another Fisher Price. We have the Van Doors running vacuums. It's all done through CAN. My question is can we run the jaguars/Van Doors through the lower current slots on the power distribution block and add the driving Fisher Price motor to a 40 Amp slot without losing too much performance on our vacuums. Thanks.
tl;dr: Can we run van door motors through smaller ports on power distribution with a 30 amp breaker. |

Re: Wiring 8+ Motors
I personally don't see why not. Last year, we were running out drive CIMs using a 30 Amp breaker, but those tripped a lot. I think van motors will be fine. Wasn't the maximum current allowed on the smaller ports 20A? I am not too familiar with it.

Re: Wiring 8+ Motors
You can run ANY motor through ANY circuit breaker slot.
However, you may want to run those motors that car actually draw 40 A or more through 40 A breakers. What that means is, motors that cannot draw 40A do NOT need 40A breakers. So take a window lift motor and run it through a 30A instead, for example. |

Re: Wiring 8+ Motors
I know this has already been said, but you CANNOT use more than 2 fisher price motors this year.
That being said, AM-0912 and banebots' RS-550 have the same dimensions and mounting geometries and similar power ratings. You can have up to 2 of the Andy mark motors and 4 Banebots motors. Since you haven't used any Banebots motors yet, you can use 4 550s or some other combination of allowed banebots motors. The RS-775-18 motors are nice, but they are heavier than 550 sized motors and have a greater shaft diameter and different mounting features. |

Re: Wiring 8+ Motors
Fred,
I have to ask how you are running a vacuum through the van door motor? |

To the OP: What type of van door motor is it? If it is the one from FIRST choice, how does it run the vacuum? Either way, Could we have pictures? |

Re: Wiring 8+ Motors
Alan,
I am thinking that any van door motor will be in the sub 100 RPM range and not easily adapted for use in a vacuum mechanism. |

Re: Wiring 8+ Motors
I have a feeling that the OP is referring to a vacuum cleaner brush.

But that is all irrelevant. Since motors supply mechanical power instead of just speed, if they had a high powered van door motor it would be easy to gear it up to achieve a higher speed if necessary as long as the power needed is within the motors capabilities. Seeing by the model plane reference, my first thought is a large, relatively slow, ducted fan. Either that or large, multi-bladed propellers which can move a lot of air at only a few thousand RPM, and still probably quite a bit at a few hundred. Personally, if I were using Van door motors to generate a vacuum, I might just use a lead screw and a giant syringe. |

Re: Wiring 8+ Motors
Fred,
Your team number is low enough that you should remember 2009. If you are planning on using a prop, it must be protected as was required in 2009. The UL Standard Finger was the guide then and would be again in this application. |
