Hmm. Good thought. I should check. I think I have a manual around here ... the redline was in the 5500 range but I'm sure I have something about Netgain testing the motor balance into the 8000 or 9000 range.
The AC motor is only rated for 9700 rpm.
If I can't locate anything that states 'the DC motor will do 9000 rpm' then I will decouple it before the next test.
