Hello Everyone,
My friend and I are considering an EV project down here in Geelong Australia. We've done a little bit of homework, purchased the Donor Car and have got our hands on a few Industrial 415VAC 3-Phase Motors.
Here is the Summary,
We would like to Build a 3-Phase controller ourselves from Open source plans or using PLCs, arduino, or something similar. The Power side will use Industrial IGBTs.
We have found a great abundance of Cheap almost new condition Industrial 3-Phase Motors and found in nigh impossible to find anything sizable in DC, these motors come with encoders for RPM, electronic clutches, mounts, heatsinks, sometimes even controllers! I have picked up one for free and other for $50. there are heaps around.
Batteries will be the last phase of the project and depending on Budget, Voltage requirements etc, I will design a pack either from AGMs or LiFePO4 (price dependant). I will be designing a cell BMS or buying a cheap kit form BMS.
As for the Vehicle, the EXA is just a starting point and may not be the final vehicle, we want to have a working powertrain before we commit to spending money on the Donor Vehicle.
Does anyone have experience building a controller for a 3-Phase AC motor? I have close friends that are electronic engineers and electricians at a large motor company, several friends that are mechanics and I work in a small industrial company. I also have access to tooling where I can have work done on lathes etc for mates rates. I will have access to VFDs IGBTs, wiring etc.
I don't want to be told that it can't be done etc. or any negative comments about my approach, I would appreciate any helpful advice from other people running 3phase AC.
I would also appreciate all the help I can get in finding any open source controllers that are AC 3-Phase. I also have access to be able to rewind the motor to lower the voltage requirements / increase RPM etc.
Initially I will be building a DC power-source to use as a simulated traction pack to test the controller design.
Sorry if that was a long first post. I do have a fair amount of techinical apptitude and tend to read and research for hours on end if something interests me.
Regards,
Adam
