Watson coil design

[brodonh]

Hi All,

Any ideas on the long thin coils seen on the Watson machines.

Reason for length - increased core material?

Small wire for thin coils?

What do I want for current from the coils to pulse charge a pair of golf cart batties?

#of winds?

I'm doing testing but have no intuition on these coils.

4 big neo's and 3 aircore/500ft #18 wire coils did much better than 6 ceramic ring mags and 5 of same coils/bolt cores.

Neo's spun at 2000rpm
Rings at 1500

Concluded: smaller wire to get voltage up with rings and r60 cores.

Ring mags are about same D as Pittsfield spools and we're spaced with ID and distance between mags the same.

Rings were mounted on wood rotor 1 flew off and went into the sheet rock.
