Bedini Motor & SSG Circuit Guide (Beginner Bedini Explained)

A Bedini motor (Bedini SSG / Simple School Girl) is the most documented pulse-motor-style circuit in the hobby. If you searched for a Bedini motor, Bedini SSG, or how the Bedini circuit self-triggers — this is the guide.

Core idea

A bifilar coil: one winding drives, one triggers. A single NPN transistor switches drive current. Back-EMF routes through a diode into a secondary battery.

Why it's popular

• Self-triggering (no separate Hall sensor required)
• Huge community documentation
• Great for learning mutual inductance and recovery

Caution

SSG does not create energy from nothing. Treat battery readings carefully (surface charge). Measure with discipline.
