Built the Electromagnetic Systems team that was responsible for development of the Hyperloop One propulsion motor and levitation system. Designed, developed, manufactured, and tested Hyperloop One's Gen 1 propulsion motor, going from concept to prototype/test in less than 8 months. Watch the 1st public test:https://www.youtube.com/watch?v=1e-Po9C8Kj8Later developed the Gen2 propulsion motor, solving how to operate a MV motor in a low pressure environment and ultimately delivering over 300 m of linear motor to support the Devloop Test program. https://www.youtube.com/watch?v=yCVHtJ6yJxo
