On March 2nd, 2018, Dr. Wang Yawei was invited by the IAS Wuhan Section to make a speech. He was an outstanding graduate of the Center for Advanced Electrical Machines & Drives (CAEMD). After graduating from HUST, he is now a candidate doctor at University of Padova. He made a report entitled “Design and Application of High-Performance Synchronous Reluctance Motors” at Room 502, West 9 Building.
In the lecture, Dr. Wang shared his research during the doctoral period, following the three sections:
1. Dr. Wang analyzed the rotor structures of synchronous reluctance motors and permanent magnet assisted reluctance motors and introduced a machine design with magnetic barriers. The magnetic barriers generate higher d-axis inductance and lower q-axis inductance, allowing high output torque and power factor.
2. For the purpose of the rotor topology optimization, an automatic optimization program for designing the rotor structure is proposed. This program can also quickly analyze the influence of certain motor structures on the motor performances and guide the motor design.
3. Dr. Wang introduced an isolated independent power generation system using a magneto - resistive or permanent magnet-assisted generators. Analytical model, steady-state performances, self-excited ability, etc., were introduced. The performances of the machines were compared.
At the end of the report, lecture participants had discussions with Dr. Wang on various topics.
In September 2012, Dr. Wang entered the CAEMD of Huazhong University of Science and Technology to pursue a master's degree and studied under Prof. Qu Ronghai and graduated in June 2015. During his Master's degree, he mainly studied the design of permanent magnet synchronous motors for electric vehicles, especially fractional-slot concentrated winding permanent-magnet synchronous motors. In October 2015, he joined the Electric Drives Laboratory (EDLab) at the University of Padova, Italy, and his supervisor was Professor Nicola Bianchi. The main research directions include: design and analysis of synchronous reluctance motors, research on self-excited synchronous reluctance generators, and optimization design of magnetic gears.
