I appologize if I have hosted this in the wrong area. Old age has fogged my memory of formulas and other things.
I am restoring a 1940-50s vintage firehouse klaxon made by IBM. This si for my son who owns a small company custom building off-road firetrucks.
The electromaget which runs the klaxon is fried (open, not shorted). In this device a horseshoe shaped, 12vac electromagnet vibrates a small hammer into a metal sounding plate. The buzzing racket is transported out two megaphones to wake up the crew and send trucks down the road.
I need to rewind both legs of the horshoe magnet. The magnet is laminated like a transformer core. Here's what I have been able to determine:
12vac, 1.6 amps, 60 cy.
Legs of themagnet are 0.45-0.46 square
Length of wound coil on each side is approximaely 1.1" long
Outside thickness of the wound coils are approximately 0.85" and are square in profile.
Wire guage and lenth is presently unknown and is what I hope to determine.
Thanks in advane for any assistance o this project. I have photos of the mechanism I could post if it would help.
