legality of PG gearmotors with obsolete part numbers
 
Below is the text of an email exchange with AndyMark tech support, PM me if you would like me to forward you the email in case you are considering using the same parts and need to show documentation to the inspector. I'm going to communicate this to the other LRI's as well. Please note the answer is for these specific obsolete part numbers - there are a lot of different PG part numbers with different motor combinations.

Hi - 2 questions regarding old gearmotors we have.

1) I have an am-0914 gearmotor that says "PG71 w/ RS775 Motor" on the label. Is the motor on this gearmotor the same as am-2161 (RS775-5), a legal motor for FRC this year?
2) I have an am-0915 PG27 gearmotor. Is the motor on this gearmotor the same as am-2194 (RS775-125), a legal motor for FRC this year?
The descriptions for those motors indicate that they are the replacement motors for the PG's, but I can't find anywhere in the description of the old PG part numbers what the motors are.

Thanks

Hi Gary
1) yes, those two motors are the same
2) yes, another match

Please let me know if there is more I can help with.
Thanks
Danny

I'd say that they are not legal. R32 states "The only motors and actuators permitted on 2017 ROBOTS include the following" and then lists the motors. This rule makes it such that motors not explicitly mentioned are not legal for use in FRC. This is not good in my opinion but I'm not on GDC so that doesn't really mean much :D. I think that it would be a worthy question to ask on the Q&A though.

He's not asking if they are legal, he's specifying they are by posting an email with AndyMark's engineers. They're the same motors that are legal, just with a different part number.

Sounds like something to ask Q & A. It could potentially get added to a team update if they truly are the same motor.

Let me clarify - the old AM part numbers said in their description that they included an RS775 motor, it just didn't say which one. The email from AndyMark confirms that the motors in those old gearboxes are RS775-5 and RS-125 and are the same as currently used in the new part numbers.

And yes, this is the correct way to go about verifying a products legality. There's no need to go to the Q&A. We've heard of other random actuators teams find with built in motors. Some teams say "it looked like a CIM motor when we opened it"... but that's not good enough. You need to contact the manufacturer and get a statement from them identifying the part number for that motor so you can verify and prove its legality.
