IF we could convince mfg to install universal motors , that work on AC or DC , as found sometimes in chain saws , low voltage dock life would be easier.
The usual motor eats power in watts , lower the volts the amps go up, raise the volts the amps go down , the watts are the same.
The universal motors are happy with lower voltage , the just produce reduced power , but they work!
Since todays air cond is in a sealed can , and universal motors have brushes , no chance , unless you go big buck and build an air cond for yourself.
