We did a break test on the PG71 and broke it with an input of 88 ft-lbf of torque.

Can the PG71 handle side loads? For example, a sprocket mounted on the shaft?

The FIRST tables show 273W for the 775-18. Isn't that the 18V number? This motor (at 12V) is much less than what FIRST states (less than half of this, or 120W) isn't it? Not too much different than the 775-12 operating at 12V

Hi Tom,

Looks like they updated the Motor Data spread sheet. I still don't think it has all the correct FP part numbers as it doesn't match Team Update #2 but I think it's correct on the years at least.

Yes, it can. There are two 10mm id ball bearings supporting the output shaft. The bearings are pressed into either side of the face plate, so that the outside to outside dimension of the bearing faces is 0.55".

As far as we can tell, the 9013 does not exist. No one has one, it cannot be purchased, and there are no specs on it anywhere. The only sources we have for this part number are from FIRST, I think its only a matter of time before FIRST finally purges any mistaken references to this mysterious part number. Until then, I'm not too worried about it since I don't have any 9013s that I want specs for. It would just be nice to know that they aren't jumbling specs for all the other motors too.

[jason701802]

We, as well as a number of other teams have received 9013's in our KOP. We have also found at least one in our bin of motors, indicating that they have come in a previous KOP as well, although it would have to be pre-2006 because there is a different FP listed in the KOP checklist for 2006 and later.

Could I talk you into taking a close-up picture and posting it please?

Thanks.

[jason701802]

I'm not in town, but I will get someone else to take a picture at our meeting tonight. The model number is very hard to read as it is etched and not printed onto the casing. We actually didn't find an old 9013 motor, but we did find a flux ring from a 9013 motor, although I have been reminded of a possible non-KOP source for the old motor.

I shouldn't sat that many other teams have received a 9013 in their KOP, but I have read a couple posts where people indicated that they received a 9013 in their KOP.

Here they are, and yes these are from this years kit of parts. (I didn't even realize we had 9013s until a few minutes ago)

Thank you.

I'm finally getting one or two Google hits on this.

PAR_WIG1350 posed better pictures than we have, so I'll leave it at that.

Does anyone have a table for 2012 Motor Specifications? From a know source.

Motor Name, Free Speed (RPM), Stall Torque (N*m), Stall Current (Amp), Free Current (Amp)
