Favored (because these qualities allow the machine do quick and nimble things for a longer time)

mechanical power

angular acceleration

torque/volume

torque/mass

torque

longevity

Neutral

resistance

voltage

loops, wire

length, wire

charge capacity

area per loop

diameter, wire

Disfavored (because these qualities prevent the machine from do quick and nimble things for a long duration)

current

mass

volume

The chart below consists of the solutions by a Microsoft Excel add-in. What the chart below shows is that in order to follow the criteria above, you have to increase certain parameters at a faster rate than others, while decreasing others in the process. The rate is r, where x=(1+r).

x^9: resistance

x^8: voltage

x^7: mechanical power

x^6: angular acceleration

x^4: torque/volume; wire loops; torque/mass

x^3: wire length

x^1: torque, longevity

x^0: charge capacity

x^-1: current

x^-2: area per loop

x^-3: wire diameter; mass; volume

Consider x=2. We would have:

512 times the resistance

256 times the voltage

128 times the mechanical power

64 times the angular acceleration

16 times the torque/volume; wire loops; torque/mass

8 times the wire length

2 times the torque, longevity

The same charge capacity

50% of the current

25% of the area per loop

12.5% of the wire diameter; mass; volume

The above suggests that while the possible mechanical power is limited by electrical power, its possible have negative relationship between power and volume, power and mass, power per current - SIMULTANEOUSLY. It's only a matter of engineering as to how small, and powerful, and how long lasting the motor can be.
