Testing of Coils in Pulse Motor
Three coils are tested here. Each coil contains exactly 50 feet of 22 gauge wire on 3 1/4 X 3/8" bolts. Each bolt, nut and 2 nylon washers were weighed to check for consistency. They all weigh 1.90 ounces. The coils are made exactly the same, except for how they are wrapped.

Coil 1 is a normally wrapped full length coil. Wrapped from bottom to top, top to bottom. |
![]() |
Coil 2 is wrapped full length except the wire is pulled down (see wrapping coils here) so all wraps go from bottom to top. |
![]() |
Coil 3 is wrapped like coil 2 except each layer is staggered making the coil conical in shape. |
TEST 1
The repulsive force of each coil is measured with a lever and a digital scale. One end of the lever has (2) 1" magnetic disc glued to it. When the coil is powered, it pushes against the magnets, which in turn push down on the digital scale. The coil voltage is controlled from a Precision power supply. The coils are supplied with 12 volts, at 2.5 amps. Below is the Setup.
