2016 Bosch motor 6004 RA3 194-06

Thanks Ryan!

I should point out that there is a thermal switch built into this motor. If you are running close to or at stall for long periods of time you will most likely trip the thermal switch. It will reset over a period of time but you would notice intermittent operation. Not to worry its doing it job to prevent catastrophic meltdown.

Well then, now I'm surprised that I never managed to trip it!

Perhaps a Round Two of testing is warranted, just keeping the motor in stall until the thermal switch trips and confirming that the motor retains its original performance characteristics after it has been allowed to cool back down.

Either way, that makes these motors seem practically rookie-proof...

Hold it at stall for around 5s and it should trip. Less/more depending on existing temperature. This switch is based on internal temperature alone.

Careful. Don't think it's "anyone" proof. Mount correctly to keep side loading minimized and you should be ok.

Does anyone know where to buy more?

Since we supply this motor "as required" by a particular Tier 1 we don't stock inventory and have it setup as a stock item in our system. We're trying to get a feel it teams find this useful this year. If it is we can look into something in future years. I'll do my best to donate replacement parts as needed but we cannot charge anything for it since we donate this to FIRST.

Two questions for you.
A) What does "Tier 1" mean? As opposed to "Tier 2"? (Not looking for names, just meanings)

B) Do you have a state space model of the motor you could share? I'd like to be able to simulate motors mathematically for some control system development & feedback tuning but getting the parameters can be difficult.

Is this a car part? If so, what car does it fit?

It's used in a seat shared across many GM vehicles for the recliner function. The list is quite extensive. The GM alpha is one:

Sorry I forget this is a common term for the auto industry but not so much for the everyone else. Tier 1 is first customer to the auto makers (we call OEM's). Tier 2 supplies to Tier 1, etc..

Not sure what you mean by "state space model". If you mean performance data you can find on Andy mark.

I wonder how one translates GM part numbers to Bosch part numbers? besides ordering one and looking at it?

I am not aware of a GM number with this motor, however, if we provide as a replacement part there must be. I'll have to check with our after-market group since I don't deal on that side of things. That is an option although quite expensive to go that way.

[MrForbes]

It would be nice to get a part number for one of them, but it's also possible that it's similar to many other seat recliner motors (I never knew there was such a thing! but I drive 50+ year old cars all the time) that might be useful.

$50 is a reasonable price for a nice slow powerful gear motor

They're pretty standard throughout the industry. Different picture going back 50yrs. The output profile varies quite a bit. This one provides one of the more FRC friendly interfaces. Maybe one of these days the auto industry will catch onto the hex craze.

FYI, the end motion of the seat recline is a result of the pretty low gearing in the motor and additional gearing in the seat mechanism.

I'll do my best to dig up the part number.

Turns out this one particular model is an exception and is not our motor. May have been an old design that carried over because this is no longer considered a replacement part. Since these are so deeply tucked inside the seat the cost of labour to replace the motor probably exceeds the benefits you would get.

We're looking into options for providing as a "purchase as needed" item but can't make any promises until we work through the details involved.

I'll do my best to offer replacement parts to teams that have received through first choice.

Hello, our team has decided that they would like to use this on an elevator component. We have a few questions on how we can implement this motor to its fullest.

1) Wiring. We have the motor +/- and have been driving them. However, we are not sure how to wire the two addition wires (additional to the motor power) to gain access to the internal encoder (Hall effect sensor?).

2) If this is a hall effect sensor what part of the RoboRio do we plug it into? Is it digital or analog?

3) If the "encoder" that is in this motor is a hall effect sensor what component do our programmers use to get information from it to base position on. Is this a Counter object?

Thanks all, and happy last week of build!
