Dínamo de corrente contínua — várias bobinas
A single-coil dynamo produces direct current, but a very lumpy one that drops to zero twice per revolution. This simulation adds coils to the armature and plots the combined output, showing how the ripple smooths into something close to a steady DC level.
Como usar esta simulação
- Set the number of coils in the armature
- Change the rotation speed
- Vary the field strength
O que observar
- Output ripple shrinks as coils are added, approaching a flat line
- The gaps where a single-coil dynamo drops to zero get filled in
- Faster rotation raises both the frequency and the amplitude of the output
A física por trás
Each coil generates a sinusoidal EMF that the commutator rectifies into a series of humps. With several coils offset in angle, their rectified outputs overlap so the combined voltage never falls to zero — the output is the envelope of the individual peaks. More coils means smaller ripple and a higher average voltage.
