Default Motor Dyno's

OK problem number one is that power numbers are difficult to understand. No matter if they are in kv or watts. Second the numbers are differrent from manufacturers, perhaps by the way they are measured or calculated, which further skews the meaning of the power rating.

So how do we as a whole hobby/community/industry come to a standard way of measuring power for both brushed and BL motors? There should also be a standard for the construction of a motor dyno. This is probably a question that is more toward engineers than hobbyist, but still we need to find a solution so that the numbers you get for a power rating are the same across the board.

As far as measurement goes, power is power no? I agree that a standard way of presenting power data is needed though, such as a power vs rpm graph and a similar torque curve. Without those curves comparison of peak values etc arent really useful. A standard test rig would help alot too.

Power numbers don't mean a lot anyway. The numbers you see on the packet is a peak figure which represents a single point in the power curve. Best test has and always will be to put it on the track.
