The PG71 IS an RS-775. It is significantly different from the one from Banebots, but my comparison was size (as in ability to be stalled momentarily without overheating) related.

Today I expect to receive several PG71 units for testing at my lab. (They were shipped on Monday.) We are working on the test set-up now. It may be tomorrow afternoon before we complete all tests, review the results, and are ready to post.

It makes sense to me....we don't want people using the power window pump motor out of a 1950 lincoln, for example.

That is what Al told me a year ago, it is a cost/benefit scenario, so they build the left versions to slightly higher quality.

Team Update #2 (2012-01-13) has added FP-9012 to [R48] and kept FP-9013.

Yes, it would be a shame to damage a car like that :D

Does anybody know the specs for the M7-RS775-18 banebot motor? The specs that FIRST gives are significantly different than the specs from BaneBots.

The 12 volt specs for both the 775-18 and the 775-12 are in the motor calculator located here.

The link you posted for the Banebots specs was for the 775-18 at 18 volts.

Here's the Banebots spec for the 775-18 at 12 volts:

The FIRST specs are for the 775-18 at 12 volts

Here is the FIRST file converted to an excel spreadsheet.

I did not make any changes to the data from the FIRST site.

All,

I have updated the web page for the PG71 gearmotor (am-0914). It now has the actual test results performed by Richard Wallace's staff at Whirlpool in Benton Harbor. Many thanks to go Richard and his colleagues for this testing and service to the FIRST community.

Copying from this page, here are the Performance Specs: (updated Monday, Jan. 16th):

Gearbox Reduction: 71:1
Voltage: 12 volt DC
No Load Free Speed: 75 rpm
No Load Current: 0.6 amps
Tested Gearbox Output Power: 44 Watts*
Stall Torque: 16.6 ft-lbf*
Stall Current: 22 amps*

Sincerely,
Andy Baker

Can we get some specs on the PG71 gearbox, i.e. efficiency and max torque?

I believe the specs you are looking at are for the gearmotor, i.e., at the gear output shaft.

Look at the pictures in the report.

The motor calculator has been updated with the new specs for the am-0914.

Still looking for specs for the FP-9013.

Re: Official 2012 Motors Models and Specs Thread

I am asking about specs for the gearbox alone. Supposing it is attached to a more powerful motor, how much torque can the gearbox take before it breaks and how efficient is it?
