LLG Micromagnetic Analysis of Perpendicular Recording Heads – Microwave-Assisted Magnetic Recording

Invited Lecture by

Dr.Eng.Yasushi Kanai

Date: Aug 10, 2015
Time:  2:00 PM– 3:00 PM
Address Department of Electrical and Computer Engineering Department, Florida International University, 10555 W. Flagler Street, Miami, Florida 33174
Room: EC-3753

Abstract: Microwave-assisted magnetic recording (MAMR) is one candidate for next generation perpendicular magnetic recording and its potential has been demonstrated by recording simulations and experiments. In a MAMR system, the spin-torque oscillator (STO) is the most important component. Some requirements for the STO in MAMR heads are: 1) the high-frequency field from the STO should be stable and as large as possible, 2) the STO should oscillate with a low injected current, 3) an oscillation frequency that excites the medium to resonance is preferable and 4) high-frequency switching following the head coil current is necessary. In this presentation a micromagnetic analysis of write heads with integrated STOs, including all interactions, will be discussed, to find head designs which satisfy these requirements.

 

Short Bio: Dr Yasushi Kanai is a Professor of the Information and Electronics Engineering Department at Niigita Institute of Technology , Kashiwazaki, Japan.He has authored and co-authored more than 130 peer-reviewedjournal papers, more than 180 international and more than 180 national conference records. He specializes in micromagnetic analysis, both in perpendicular magnetic recording heads and media, and electro magnetic field- heat transfer coupled computations of hyperthermic treatment.

Bearingless Drive Techniques

Invited Lecture by

Masahide Ooshima

Date: Aug  04, 2015
Time:  11:30 AM– 12:00 PM
Address Department of Electrical and Computer Engineering Department, Florida International University, 10555 W. Flagler Street, Miami, Florida 33174
Room: EC-3753

Abstract: Recently, the bearingless motors are receiving attention in some special cases, particularly, for high vacuum and the other environment where the lubrication oil cannot be used. In this lecture,the concept of bearingless motors and itsdrive techniquesare introduced. And then, as a recent topic, the bearingless motors with the integrated windingis focused, in which only a kind of winding is wound in the stator core for the motor drive and magnetic levitation. A novel technique of the bearinglessmotor with the integrated windingis introduced.

Short Bio: Masahide Ooshima (M’94-SM’13) was born in Aichi Prefecture, Japan, in 1965. He received the B.S. and M.S. degrees in electrical engineering from the Tokyo University of Science, Japan, in 1989 and 1991, respectively. He received the PhD degree in Electrical Engineering from the Tokyo Institute of Technology, Japan, in 2005.

He is a Professor in the Tokyo University of Science (TUS), Suwa. He has been engaged in research on bearingless drives, adjustable speed AC drives and super high-speed drives.

From 2004, he is the member of the Electric Machinery Committee and Motor Sub Committee in the IEEE Power Energy Society (PES). From 2013, he is the vice chair in the Motor Sub Committee. From 2010, he is the member of the IEEE Industry Application Society (IAS), Industrial Automation and Control Committee (IACC). From 2014, he is the vice chair of the Japan Chapter of IEEE Industry Applications Society. He is a senior member of IEEE from 2013.

Harmonic Domain Modeling for Power System Devices

Modeling Of Magnetic Devices : Transformers , Reactors

Invited Lecture by

Dr Aleksandar Damjanovic

 

Date: Feb  10, 2015
Time: 06:30 PM– 07:30 PM
Address: Department of Electrical and Computer Engineering Department, Florida International University, 10555 W. Flagler
Street, Miami, Florida 33174
Room: EC-2440

 

Abstract: The main objective of this research is to develop mathematical models in the harmonic domain for irregular or special shapes of transformer hysteresis loops including families of hysteresis loops. The research is focused on unusual shapes of hysteresis created by mechanical stress on oriented silicon steel, rectangular loops, perminvar loops, isoperm loops and composite hysteresis loops created by multiple magnetic phases. The models of this research should accurately recover nonlinear characteristics of the transformers that include hysteresis.
