Post-Doctoral Research Fellow
Dr. Hao Ge
From humble beginnings in a very small village in southeast China, engineering was in Hao’s blood. As a child, he liked taking things apart and trying to put them back together again. In most instances he was unable to put these things back together, which made him the black sheep of the family. Even though he knew nothing could be perfect, he still wanted to pursue perfection within imperfection, which just happens to be a part of his engineering philosophy. Inspired by an aerocar inventor, Hao has wanted to be an automotive engineer since he was in his second year of high school. At the time, he looked at it as the perfect job that was not only of great interest to him, but could also help him acquire great wealth. Though he attended the Electrical Engineering Department in university, he had the chance to study automotive systems at the Institute of Electromagnetic and Electronic Technology, Harbin, which was named the Electric Vehicle Research Center.
Hao started his research on a variable reluctance resolver, which is a position sensor often applied in electric vehicle (EV) drive motors. He is very proud of that project because he was finally able to make a resolver by hand that was compatible with the product on the market, and it even had better accuracy. During this project, Hao gradually came to understand the electromagnetic theories in electric machines, such as windings, harmonics, and inductance. What’s more, because he needed to develop a differential resolver for the digital (R2D) board, he had to put the control and circuit theories into practice and needed to dig out information from other disciplines like modulation and demodulation, PLL, and coordinate transformation. He’s glad that he worked on that project and it really helped him understand what research is and how to complete it.
During his master’s research, Hao worked on an electrical variable transmission (EVT), which required him to understand the vehicle, powertrain, electric motor, control strategy, and mechanical manufacture. He is currently working as a Ph.D. student at the McMaster Institute for Automotive Research and Technology (MacAUTO) and his research is mainly focused on switched reluctance machines (SRMs) and fractional slot permanent magnet machine (FSPMSM) design and control. Hao is especially interested in hybrid machine development, which would allow him to utilize the benefits of both reluctance torque and permanent magnet torque in a concentrated winding machine.
Apart from his work, Hao enjoys sports and outdoor activities, especially basketball and cycling. He also enjoys large bodies of water, stating that by jogging and cycling by the lake, he is able to appreciate the wind and tide of the sea. In the future, Hao hopes to pursue a career in electric vehicles industry and home electrification. He has dedicated himself to electrical engineering and hopes to achieve greater success in this area, helping to promote social progress. Hao is a goal-oriented person with the ambition of promoting the expansion of electrification. This is what drives him work hard on his research.
