This week I spent a lot of time practicing for the Design Review presentation and working on the Design Review Report. The Design Review presentation went fairly well based on the feedback. The next major thing I did as I was writing the Report was reviewing the basics of motor operation. In order to describe the differences between brushed DC motors and 3-phase brushless motors as part of the Report, I found a good source that described the basic operation of both types of motors. This review helped me ensure that I understood the operation of a 3-phase motor and how Field-Oriented Control relates to it. The next bit of theory that I will need to look into will be how to actually estimate the rotor position. This is a much more difficult and theory-heavy area that will require additional time to understand.
