@stuartfram inverter hardware

So I have started a project to design an open source logic board for the Tesla Model S large drive unit. Basic idea is to use the Heubner inverter system as the heart of a new logic board that will be a drop in replacement for the tesla original. Already proved the motor will run on the bench in slip control and just today worked out the connections for the igbt driver boards in the inverter. I'll use this thread and github to keep track of progress and discoveries. Things learned so far : Motor is 4 pole Encoder: 36ppr , 5v supply and has internal pullups to 5v All internal board connections made by JST connectors (pdf attached). Readily available from mouser. IGBT driver boards have 8 connections. GND , +12v , High drive , Low drive , High fault , Low fault and 2 unknown. Suspect they could be a temp sensor , fault reset or maybe both. Pinouts to follow.
