This is the schismatic of a brush-less DC Pulse
Motor/Generator that collects back EMF.
Back (EMF) Electromagnetic-field
The source return collapsing magnetic field that, if allowed to return to the source would annihilate the source.
An inductor, also called a coil or reactor, it is a passive two-terminal electrical component which resists changes in electric current passing through it. It consists of a conductor such as a wire, usually wound into a coil. When a current flows through it, energy is stored temporarily in a
magnetic field in the coil.
Building the Coil
First we need wire to make the coil. We then wind both coils at the same time, they will have equal lengths, a 1 to 1 ratio. In order to make the coil we need a spool so the wire keeps its shape made out of 4 inch PVC pipe. Then we hot-glue the wire together to the pipe.
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical
power. It is composed of semiconductor material
with at least three terminals for connection to an

The function of my Motor/Generator.
- Reuse the back EMF to run lights, or charge
batteries. Changing the resistance changes the
trigger time of the sensor coil allowing to tune
the motor to optimal speed. Also to create a
more efficient motor.
- The lights use .7 watts each so we are getting
almost 3 watts of light energy off the coil after
the transistor turns off the pull of the coil.
