Tom's motor and controller (AC Drive) are industrial standard equipment. It's the sort of thing designed to run a big electric motor in a factory.
Buying anything that is designed for a very specific purpose, with a very small target market, is always VERY expensive - such as EV AC setups.
I don't remember what Tom said the value of the motor and drive were, but they were relatively inexpensive. The trick is to know how to modify them to make them work for this application.
I think that the controller (AC drive) will be one of the next things installed when we are all done with the battery boxes.
When we do that, it should be a good time for another video with Tom explaining how it's all going to work. At that time, I will try to get some budget numbers and motor/controller specs as well.
