Hello to the All About Circuits Community . This is my first post.

My name is Ian ORRELL and am a retired Mechanical Engineering Associate/Technical Teacher and a Vietnam Veteran.

My interests are many. Since I retired in 2002, I don't know how I ever found time to go to work. Has anyone found days with 48 hours ?

I've knocked on Heaven's Door a couple of times and life is too short.

At the moment I am collecting parts for a 10 - 12.5 kW Induction Furnace.

General Information.

1. Incoming Mains Supply 415V 3 phase 59 Hz. 16 mmSq.

2. I have collected some 1000V 75A IGBTs

40 A 3 Phase Bridge Rectifier,
High Current Diodes
High Current SCRs

Refrigeration components for the cooling of the heat sunk electronics and Induction Working Coil and many more smaller components.

3. A foundary friend of mine runs a new commercial 125kW [Cast Iron] and 75 kW [Non Ferrous] Induction Furnace for a Technical College. The operating frequencies vary between 2.5 -3.5 kHz.

Has any one out there built any thing like this, as I would like to contact them ?


Kind Regards

Welcome to AAC.

The skills you are talking about may be in short supply, but then again, there may be some one around who can help.

Mars has a 48 hour day. Does that help? :D

The name of your thread is very important to getting the kind of help you want. I'm going to modify it a bit so people will notice your problem, no one can read every thread posted here, though some try.
