yep, same type of thing really, one option is to do a normal ramped acceleration run on the moto dyno (as per the ones in my last post)
and another more torturous but controlled option is my lathe as a dyno, i can set its own motor/gearing to run at say 55rpm, you then apply throttle measuring phase
amps and torque output from the load cell etc and the motor/lathe rpm stays right where you first set it with the test motor now attempting to overdrive the lathe.
theres no audible change in note from this effort so you have to keep an eye on power levels cos last time i ran 7ish kw of power in and oddly the lights went really bright and i shut it down, turns out there was about 5 or 6kw going into the grid and the 240v ac had risen to over 270v and nearly blew the house fuse the wrong way
-handy though cos many kw of heat can be a real pain to get rid of during an extended test, and it was dissipated by my good neighbors..
anyway if people want it tested ill do it, working our way up to whatever max amps you like, i dont really plan to just blow it up, so all going well someone can still use it. -i might see what luke reckons?
