As you can see in the photo. The junk equipment I bought cheap-if I can get it to work varies. The Ac Sine wave power applied to the motor all the way to 20 thousand volts. That means I can vary the static thrust from low to maximum within the 20 thousand volt spectrum. That sets aside any skeptism about the motor being useless junk NASA rejection letter you received. The Fact of the matter is the device passed on to the skunk works long ago and there are some drone UFO’s being tested in secret at much higher voltage potentials.
