Exploded CAD model of the axail flux motor

A high pole count axial flux motor allows for extremely efficient use of energy and a very powerful electromagnet motor. The motor is comprised, at its most basic level, of 3 parts: rotor, stator, and shaft. The rotor houses the specifically spaced, alternating pole, magnet configuration. There are two rotors on either side of the stator. The stator houses the wire coils, which are arranged so that they repel or attract a magnet on the stator at a precise instant in time to allow the rotors to spin while the stator remains stationary. All of this is fixed to a shaft to transfer the mechanical energy. The magnetic flux generated by wire coils repels (or attracts) magnets close to it, which done with specific timing allow the outside rotor to spin. However, the reason why these motors aren't in widespread use is because they are hard to control. The objective of this project is to design, and control, a high pole count axial flux motor using Hall Effect sensors and optical encoders. This project would not have been possible with out the help of Erik Bettis, Jesse Caldwall, Jeffrey Campeau, Joshua Saylor, Tim Waller, and Gideon Prior.
