Calling All Brainiacs!

With eagletree and similar products building a dyno is fun but only if at the end you plan to put sticker on BL motor with power ratings.

Math and software is simple, even electronics are not that bad. Spinning motor shafts at high RPM with high torque is the problem.

You can use 2 motors one as load and another as test. Monitoring shaft load with torque sensor, temperature and phase current and voltage on both motors plus encoders to monitor RPM will allow you to plot DYNO data. Data acquisition system must be at least mid-to-high end.

Or you can spin a drum, and only use data from one motor...

P.S.
For power use 1-3 12V Car batteries (cheap and easy)
