All,
When my contact first told me about it being a six volt motor I was a bit disappointed, but I asked him a few questions. Disregard his question to me in the quote below. The Excel grid I attached in my previous post does have the data for 6 volts, too. That data is on another tab in Excel. I can test one of the motors I have and see what it can do, but I bet limiting the voltage to the FP motor is probably a good idea. The thing that bothers me the most is the engineer from Mabuchi did not jump up and down and say, "No way! Do not use it at 12 volts or you will destroy the motor." In my experience, however, the motor will fry near stall conditions at 12 volts. I am confident that the information I have received is accurate, but the missing piece is the robustness at 12 volts.

Paul,
It was nice speaking with you earlier today and Mabuchi Motor is pleased to
support programs which challenge the young minds of tomorrow's work force.
I had an applications engineer, Mr. Dustin Ridgeway, pull off the
performance curves from our data base on the
PF # 74550-0642 , motor RS555PF-8021 you requested. Per our discussions,
the motor is basically a 6.0 V nominal motor
as compared to the 12.0 V RS555PF-6534 you are accustom to.
It can be operated upwards to 9.6 V and for short time duration 12.0 V may
be acceptable.
Can you downgrade the battery to 6.0 V ??
If you have any further questions, please feel free to contact us for
assistance.
