Greetings!
I'm currently still waiting to hear back from the electric motor company. I think waiting is the hardest part considering that the project should work considering the math involved. Once the electric motor is in, I should be able to get the compressor housing back plate made as well as mount the compressor wheel to the shaft and ultimately the compressor housing.
When that is done, I will do some fitment tests to make sure that the wheel is not hitting the walls on the compressor housing and then I will proceed to attach the electronic speed controller on to the motor and Arduino board.
After that's done; the batteries would be the only thing left to start some real bench tests! I'm thinking of using 4 car lead acid batteries for the sake of testing and then finding something more compact for real world applications.
Then there's the matter of cooling the motor.
Still have a ways to go!
