Banebot 775 versus FP motor

de1 · January 30, 2011, 1:21pm

Anyone have any good comparision data of the 775 running at 12v compared to the FP motor ?

Attached is the motor curves data sheet from the FIRST website.
hope it helps.

I believe the 12 volt RS775 data in that PDF is incorrect. See this thread.

…or this one.

yeah its 18v but the motor is still run at 12v, the motor running at 12v is what is in the data sheet

Yes, it appears this document has been updated. The initial motor curve sheet posted by FIRST used the wrong 775 specs.

Yes, it was updated on the 26th

Has anyone here measured the locked-rotor inductance for the RS775, or seen a spec for that anywhere?

If not, how about scope traces of the locked-rotor motor current when running with the Jag at low duty cycles (like say 20% or so).
