Tesla Patent # 577670

I think it was much better to replace the commutator with vibrating switch or relay.

I think it was much better to replace the commutator with vibrating switch or relay.

I think it can be done with mosfets and a timer circuit.

relay is better than mosfet in this circuit because it can handle large current, has low resistance and have fastest rising time.

Hi Everyone, thank you for your interest and responses, very much appreciated.

I originally posted this patent in another thread because I thought it would be interesting to make it if you could using off the shelf parts and an electronic controller instead of a commutator and brushes. 

Since I don't know enough about electronics I thought I'd ask if it was possible.

I think because of the short in the circuit at different points maybe using brushes is the only way this circuit would work.

At any rate it's an interesting circuit.

@Mags, hope you're feeling better, I agree with your push-push analogy, interesting.

@elementSix, I've read the 568,178 patent and agree with what you stated, it's interesting that patent 577760 was filed later and uses a totally different arrangement than the previous, is it like you mentioned that maybe "pulses both the negative and the positive at the same time??", that's an interesting thought. 

@Neo-X, when I look at the patent and the placement of the brushes I see a short in all three brushes then only two then three again, alternating both sides of the circuit with a short in between, could you time this sequence with relays?

Thanks everyone,
Paul

Maybe it can.. I noticed in the circuit that theres no spark gap. If it has no spark gap, the spark will appear in the commutator. Does this mean it was operate at low voltage or the commutator is a rotating spark gap and not really a commutator?
