These are high current - low voltage motors made for demonstrations. However they can make good base for industrial use. I have principle of operation explained by circuit diagram. Enjoy!

![Universality of Free Fall (UFF) debunked ?
The following video shows the experiment,
inside of the (aluminium) drop capsule
in the drop tower (110 m) of ZARM.
During the fall of the test bodies
(Lithium [Li], Beryllium [Be], Boron [B],
Carbon [C],
Aluminum [Al], Iron [Fe], Lead [Pb])
you can see the different accelerations
Mainstream physics says that all bodies
should all have the same acceleration,
which is equal to the formulation
“inertial mass is equal to gravitational mass”
which is clearly not the case here..
So the Universality of Free Fall (UFF)
is not so Universal after all ?
Or maybe there is only inertial mass?
