Parts for Synchronous Spark Gap

Another box arrived swiftly from the US. Eagerly unpacked to find a synchronous salient pole motor from Teslastuff.com. This will drive my rotary spark gap. I am informed this is the best way to go for a reasonably large Tesla coil.






As far as I understand (limited but growing knowledge) this motor rotates directly proportional to the AC frequency. This allows the spark gap to be timed so the gap is presented as the capacitor bank reaches an optimum charge level. I found an excellent article on the different types of spark gaps used explaining how they work and pros and cons. The article is by Richie Burnett and can be found at http://www.richieburnett.co.uk/rotary.html






Will need small step down transformer to power it at 115v.
