Re: 12v vs. 24v Globe gear motors running at 12vdc: what's different ?

The wire in the windings for the 24 volt motor is thinner but longer.
The cross sectional area of the wire is half as much, but it is twice
the length, so you get double the number of turns. The total
volume of the windings is the same.
That explains it perfectly to me! Now I think I understand how essentially
the same size package can have different voltage requirements:
more turns = more EMF
longer & thinner wire = more resistance so you need more voltage
Right ?
Right.
The real limits on DC motors are current (amps) and power
(watts).
