Comparative Power/Weight Ratio
Comparative Power/Weight Ratio
(OP)
Is it correct to say that, given a common set of criteria, a heavier (larger) motor will provided a greater power/weight ratio then that of a smaller motor?
The criteria would be that of a modern high performance motor that is brushless, has rare earth magnets and perhaps is an outrunner.
Thanks,

Some smaller motors could easily have a higher P/W ratio. They can afford to have those exotic magnets. They don't need massive shafts and mechanical structures to transmit the power.
