Powering and controlling Window Motors
We are trying to get the Window motors (2011 KOP) going. As lead mechanical and electrical, i am trying to figure out how to connect power and PWM(?) cables to control it.
The Window motor we have has a cable connect for power, but I cannot find any cable in the kit of parts that fits in the connector to power it up. Does anyone have any documentation for connecting/hooking up the Window motors? -Team 3481 |
Re: Powering and controlling Window Motors
They are run through a jag just like the cims. to attach power to the motor, we cut away the plastic and put a fitting around the little ends, I don't know the names for it, sorry..

Re: Powering and controlling Window Motors
How are you able to determine which one is positive and which one is negative?

Re: Powering and controlling Window Motors
You can get the connectors online at places like digikey, I've found hte PN by searching on chief before. You can also get them in some autoparts stores.
I'd reccomend just chopping it off and soldering wire right to it however. It does not matter which is "positive", as it's an electric motor. You can hook it up either way. |
Re: Powering and controlling Window Motors
Thanks for quick reply!
Plastic is stripped and crimp-on quick disconnect terminals are on, next question is what AMP should we connect the cables to on the PDB and what size(gage) on the cables to use? |
Re: Powering and controlling Window Motors
You should connect the Spike, Jaguar or Victor powering the window motor to a 20A breaker on the PDB. You should use the wire gauge specified in the manual for 20A circuits or larger (smaller gauge number) to make the connection.

We used the 40A breakers last year =/ |

Re: Powering and controlling Window Motors
Some teams have had issues with window motors + jaguars. If you search the thread there are a few topics on it. Some team don't have issues but the ones that do usually switch to victors and are fine.
Al, why would they stall at different currents with what appears to be identical specifications? Is the left less efficient? |
Re: Powering and controlling Window Motors
We used 40A Breaker with 12 gauge wire for both of our window motors with a Jag. We just used crimp on terminal connectors to hook it up. You can buy the real connector however, but only in a bulk of 1000

Re: Powering and controlling Window Motors
Trent,
My guess is that the left hand motors generally will get more use so they are built a little heavier. Economy of using slightly smaller wire in one design adds up when you are producing a few million units. |
Re: Powering and controlling Window Motors
Doesn't this have to do with the brush angle and phase offset?
Many brushed DC motors are more efficient in one direction than the other. |

I've been an electric motor designer for many years. Two general rules govern sizing of motors: (1) magnetic circuits (the magnets and steel cores) are sized to provide the required maximum torque, and (2) electric circuits (the windings) are sized to provide the required cycle of service without overheating, and without wearing out the insulation too soon. In this case, the service cycle of Left Window motors is indeed more severe than that of Right Window motors. |
Re: Powering and controlling Window Motors
the parts needed to make the connector for the motor are the following
Packard parts 1pc 12129487 connector 1pc 12077904 TPA(lock) 2pcs 12010293 seal 2pcs 12110845 terminal You should be able to get them anywhere you can get Packard connector parts you might need some wire |
