Joint PES-IAS/LMAG Meeting: "Magnetic Levitation and Bearingless Motors"

We each interact with no fewer than a dozen different electric motors every day. These electromechanical devices have become fundamental to our existence, pumping the water we drink, generating the electricity we use, aiding in heating and cooling our homes, and even providing our means for transportation. Electric motors are estimated to consume 45% of global electric energy, making them the single biggest consumer of electric power and an important technology to target for efficiency improvements in an effort to decrease our global energy footprint. Typically the first point of failure in electric motors, and a source of significant energy loss, is the bearing system used to support the motor's shaft.

This talk will investigate using magnetic levitation to eliminate bearings from motor systems and create ultra-efficient, high speed, "bearingless" motors. This technology is specifically targeted towards overcoming obstacles in bearingless motor technology so that it can be used in large systems across the industrial and energy sectors where it has the potential to offer tremendous energy savings, size reductions, and intelligent, self-monitoring capabilities. A new type of motor winding technology, referred to as "dual purpose no voltage" windings, is proposed to overcome critical challenges that limit the efficiency and manufacturability of legacy bearingless motor systems. The proposed windings are able to re-use the electric motor's coils to create magnetic levitation forces on the shaft in addition to torque. The end result is a highly integrated, electromechanical device that is easy to manufacture and uses little raw material.

Eric Severson received the B.Sc. and PhD degrees in electrical engineering from the University of Minnesota in 2008 and 2015, respectively. He worked as a post doctoral researcher at the University of Minnesota from 2015 to 2016. He then had a brief stint in industry as a principal electrical engineer at McMillan Electric Company. Dr. Severson joined the University of Wisconsin-Madison in August 2017 as an assistant professor. He is a fellow of the Grainger Institute for Engineering and associate director of the internationally recognized Wisconsin Electric Machines and Power Electronics Consortium (WEMPEC). His research interests include bearingless electric machine design, power electronics, and flywheel energy storage.

March Section Meeting: "Thorium and the Waste Issue"

Dr. Steeves will review fission, actinides, fission products, and a comparison of thorium with uranium, especially with regard to thorium’s use in molten salt reactors instead of light water reactors. His remarks are directly relevant to our concept of nuclear waste, which is so badly misunderstood by the media and most of the public

Bio:

Dr. Richard Steeves is an Emeritus Professor of Radiation Oncology at the University of Wisconsin School of Medicine with interest in reducing carbon dioxide emissions and the severity of future climate change. Since 2010 he has been leading a discussion group, called “Pathways to a Sustainable Planet”, for the University’s Participatory Learning and Teaching Organization. His experience in handling X-rays and radioactive isotopes, both in the USA and at the Curie Institute in Paris, prepared him for delving into the potential benefits of atomic energy for solving our impending climate crisis. Cleaning up our generation of electricity is a good way to start, for transportation as well as for home and industrial use. Richard drives an electric car and flies an electric airplane. He would much rather plug into a grid like Illinois’ than Wisconsin’s, and he believes we will need more than renewable energies to accomplish this.

  • First Tech Challenge Donation to Sector67: Chris Meyers writes: "A little belated, I wanted to send a THANK YOU! for your generosity in sponsoring our FIRST Tech Challenge robotics team this year.  We participated in the regional competition in Appleton two weeks ago and the students had a great time. We were able to bring 3 students to the competition, with roughly 6-8 students working on the robot at various points in the construction.  They participated for the first time in the competition and learned a lot!  The students are all excited at the opportunity to compete again next year, and are looking forward to improving on what they learned this time around.  Ultimately we placed 12th of 14 teams, and with a little driving experience before the first time in the competition we expect to boost performance next year 🙂  They were able to program the robot to complete some objectives in the 30 second autonomous period that scored a lot of points, as well driving remotely to score some more points and help their partners. In short, I wanted to thank you for your donation to support the team, I look forward to updating you on next years progress! "

Reviews of Past Meetings

Review of January Section/LMAG EMB Meeting

Dr. James Lattis presented an interesting historical talk on the significant development of electronic light measurement instrumentation and techniques for astronomical observations. Prior to electronic measurements, a system of comparative visual observation was used to rank the brightness of astronomical objects, particularly stars. Later, photographic emulsions were able to characterize object brightness, but measurement was tricky due to variations of emulsions and non-linear effects in exposure.

Enter the electronic age.  In 1894, a selenium photocell was first used to measure astronomical light intensity, but sensitivity was limited.  In about 1907, George Stebbins at the University of Illinois used a chilled selenium photocell and sensitive galvanometer to measure astronomical objects, with the first accurate measurements of the variation of light from the orbiting binary star system named Algol. With and estimated accuracy of 2%, this was much better than visual or photographic measurements.

After the discovery of the photoelectric effect, Professor Jacob Kunz at the University of Illinois was able to make tubes with a metal-hydride cathode and argon gas that achieved a modest ionic amplification. The result was an instrument that had better than 0.4% sensitivity, better noise performance, and very fast recovery time when coupled to a string electrometer for readout. Stebbins brought the Photoelectric Photometry  (PEP) technology to the University fo Wisconsin in 1922 and continued to develop it here. The Kunz tube design was improved and coupled to GE electrometer tubes, immediately improving sensitivity by a factor of 4 or more.  This Kunz tube/Whitford amplifier was the best scientific light detector available until after WW2.  Washburn Observatory alone was producing good science with them and training other astronomers in PEP. Washburn continued the advance of PEP with the addition of the photomultiplier tube in 1936 and later added image intensifier tubes.

Review of January (cancelled) February 12th (rescheduled) ECN Meeting

The "Polar Vortex" hit causing the initial meeting cancellation.  A rescheduled meeting at Sector67, held on February 12th reviewed the presentation and discussed the results.  Though it looks like the device is ready for any HVAC technician to install, the general consensus among those attending was that they were not convinced Rossi had a real device.  Most present wanted independent confirmation of the extraordinary results.  The presentation is available at this link.
