Master’s Thesis Proposes Methods to Reduce Cogging Torque in Magnetic Gears

“A New Method for Cogging Torque Mitigation in Magnetic Gears” was the title of a master’s thesis by Mohammed Khudair Rashid at the University of Technology. The study introduced two innovative methods:

1. Segmentation Technique: Achieving a 97.53% reduction in cogging torque in the inner rotor and 42.23% in the outer rotor.
2. Radial Slotting of Stator Poles: Testing various configurations resulted in an 81.9% torque reduction in the inner rotor, with a minor increase of 2.75% in the outer rotor torque.

The examination committee comprised:

• Prof. Essam Mahmood Abdul Baqi (Chair)
• Dr. Suad Ibrahim Shahl
• Dr. Ahlam Laibi Shureiji
• Dr. Ahmed Mahmood Mohammed (Supervisor and Member).
