Open Source Induction Furnace

Induction furnace circuitry and melt chamber design is sought. The bids will be judged on the demonstrated competence of the bidder, and upon the extent of design completion. The complete design would include any or all of the following: 1. Design of an induction furnace circuit scalable up to 50 kW in units of 1 or 5 kW 2. Design allows for power and frequency selection 3. Power source may be either 1 or 3 phase electrical power. 4. Specifications of a cooling or heat dissipation system 5. Adaptable design specifications for primary coil windings 6. Geometical design of melt chamber and basic power transfer calculations 7. Melt chamber includes provisions for loading and pouring. 8. Complete bill of materials 9. Fabrication files for circuit and other components 10. Sourcing information for components 11. System design and process flow drawings We have a budget of $3k for the design work. Please see blog post on this issue - [login to view URL]
