This paper reports a new design topology of 4 pole hybrid electromagnetic levitation system in conjunction with linear synchronous motor. The mover, 4 pole hybrid electromagnet, is levitated underneath of the linear motor with zero power control algorithm. Propulsion and one-dimensional planar motion of the hybrid electromagnet is provided by the vector controlled linear motor. The new design of 4 pole hybrid electromagnet has several improvements over older systems, such as weight reduction and less material usage. Diagonal drive integration of mover and linear motor is proposed and experimental results are presented.
Frederic joined as a Research Engineer in July 2015. Prior to DeepMind, he was a research engineer at the Foundry, a VFX software company. Frederic’s job is to accelerate research, and take the lead on the engineering side of projects. He mainly focuses on generative models, which is a family of models belonging to the field of unsupervised learning. He describes his job as trying to teach a computer to process data like the human brain: "To dream and imagine things that it has never seen before. One way to achieve this is to show the computer a lot of data and let it figure out why things look like they do.” Frederic joined DeepMind to be a part of our exciting and challenging mission to solve intelligence. His favourite DeepMind memory was watching the AlphaGo vs Lee Sedol match: “The suspense and atmosphere in the office was amazing.”
