## Main Question or Discussion Point

Given an unconstrained (suspended without contact to anything) electric motor with its own power in total has mass m1

Given the motor shaft is connected to a payload of mass m2

If m1>m2 then: m1 no-spin + m2 spin

If m2>m1 then: m1 spin + m2 no-spin

What happens at the unit ratio (m1/m2 = 1 or m1=m2)?

Aside from the unit ratio are there any other non-trivial ratios which determine which mass spins the other?
