Exciter size

[JohnR]

Mr Bach-man -

It was difficult to determine the size of the exciter in the Porter due to it's placement.  If it's not infringing on a trade secret, how big is the actual exciter?

Thanks

Dear John,
It's about the size of a dime.
Pretty cool!

A dime is about 3/4 of an inch in diameter.

excuse my ignorance, but what is an exiter?

Instead of a speaker!

I take it this means essentially the locomotive's body becomes the speaker?

Does this mean that an exciter is essentially the magnet and coil so that the body of the porter sis actually the "cone" of the speaker?

Thanks , it clear to me now.
essentially a speaker coil with magnet and you use the body of the loco as speaker cone.
