idea for current limiting of MOTs



Original poster: "D.C. Cox" <resonance@xxxxxxxxxx>



Tesla coil list members looking to limit MOT current might explore this idea: Tractor Supply and Farm and Fleet stores or other farm co-op type stores usually carry "stock tank heaters". These are 220 volt and usually run at 20 Amps in normal service. They are very inexpensive and an experimenter could connect several (3-5 pcs) in parallel to lower the resistance to a value that might provide excellent primary current control with MOT type transformers. An experiment is in order.

If any one does this please advise the list on what you find works well with single MOTs and a pair of MOTs with the secs series connected for higher output voltage.
