In early 2001 I spent two months in Thailand creating a plan for maintainable and sustainable small-scale stand-alone photovoltaic systems to be used to power educational tools in order to improve education in rural hill-tribe villages of Thailand.
My website dedicated to the project can be found here: iqp.andrewkeefe.net.
Upon graduating in 2003 I was offered a job at DRS Power Systems as a Systems Engineer, a continuation of part time work I had been doing at DRS for six months while finishing up my senior project. At that time we were developing the world's largest permanent magnet motor and drive, a 36 MW six-phase machine with segmented stators, to be used on the Zumwalt class destroyer for the Navy. My job was to model the motor and drive (in Matlab/Simulink and Ansoft's Simplorer) and use simulations to validate design criteria such as torque ripple, modes of operation (torque, speed, and power), and emergency braking distance known as crashback.
After two years at DRS I was contacted by Raytheon Integrated Defense Systems, who was looking for an electrical systems engineer who was familiar with the power distribution system onboard the Zumwalt destroyer. As lead systems integrator Raytheon was responsible for charactarizing all of the onboard electrical systems on the destroyer and submitting that information to the company who was developing the power distribution system (which coincidentally happened to be DRS Power Systems). I joined the team at Raytheon and acted as the primary interface between the Raytheon and DRS teams.
About two years later, as that work was coming to a close, I was contacted by BAE Systems, who was looking for a systems engineer with electric drive controls experience to work at a new facility in Massachusetts developing and integrating hybrid vehicles. At that time BAE Systems HybriDrive system made up the four largest mass-transit hybrid fleets in North America. My work was to adapt both their commercial and military systems to various platforms including the Army Stryker, Marine Corps Humvee, Freightliner Class-8 truck, and the new Joint Light Tactical Vehicle (JLTV). I architected the control algorithms on the new military vehicle systems while leading a development team of systems engineers, controls engineers, and software engineers in their implementation and testing.
BAE Systems closed down that facility in 2009 for budget reasons. BPG Motors was my next stop, this time as the lead engineer developing a new form of transportation known as the Uno. Traveling on two side by side wheels and balancing similar to an iverted pendulum the newest prototype also transforms into a low-speed electric motorcycle. As the lead on the project I am responsible for the overall engineering approach, testing, and development of requirements. I am also the controls lead, developing and testing the algorithms for balancing, tilting, and transforming.
The following video is of me transitioning from Uno to Motorcycle mode without having to put my feet down.
