Complete written guides on pulse motors, Bedini SSG circuits, coil winding, back EMF, and more. Written by Papa Bale — self-taught experimenter.
Understand back-EMF spikes, pulse width, transistor switching waveforms, and what a healthy vs troubled pulse motor looks like on a scope.
N52 vs N35, disc vs block, how many magnets, polarity rules, and safety considerations for high-RPM builds.
How pulse motors differ from standard DC and AC motors — pulsed vs continuous current, back-EMF recovery, and why each type excels at different things.
Back-EMF charging, surface charge vs real capacity, honest measurement methods, and why supercapacitors may give clearer results than batteries.
How to wire, position, and tune a Hall effect sensor as the trigger in your pulse motor — replacing the traditional bifilar trigger coil for adjustable timing.
New to pulse motors? This is your starting point — recommended first build, tools needed, and links to every guide you'll need.
Definition, history, how pulse motors work, back EMF basics, and why the hobby is so compelling. Start here if you're curious but not sure what a pulse motor actually is.
Step-by-step build guide with full parts list, coil winding basics, transistor circuit wiring, and tuning tips from Papa Bale.
John Bedini's famous Simple School Girl circuit explained — components, how it self-triggers, and back EMF recovery built in.
Compare common transistors for pulse motors — switching speed, heat, current ratings, and Papa Bale's recommendations.
What back EMF is, why it matters, how to measure it, and how to build a BEMF recovery circuit to improve efficiency.
Bifilar vs single winding, core materials, winding direction, resistance targets — everything you need for a great coil.
16AWG vs 20AWG vs 22AWG — Papa Bale compares the tradeoffs and shares his personal experience with 16AWG coils.
Rotor types, magnet selection, placement polarity, balancing techniques, and bearing choice for a smooth-spinning pulse motor.
Not the same thing! Learn the real differences between pulse motors and Bedini motors — circuits, efficiency, use cases.
Papa Bale's honest take on the overunity debate — what experiments actually show, and why pulse motors are fascinating without overclaiming.
