Unequal-Teeth stator structure for a Low-Vibration: source and project details
| Research overview |
This project tackles the high vibration and noise that appear in fractional‑slot concentrated‑winding permanent‑magnet synchronous machines (FSCW PMSMs) used in electric vehicles. The machine studied has 30 poles and 36 slots. The work looks at how high‑order radial electromagnetic forces are turned into low‑order radial forces because of the teeth‑modulation effect. To reduce this problem, the authors propose a stator with unequal teeth. Radial electromagnetic forces are evaluated with the Maxwell stress tensor method, and the modulation process is examined. Finite‑element simulations are run to see how the unequal‑teeth shape changes the amplitude of the low‑order radial forces that result from modulation.
By finding the best tooth‑size ratio, the modulation effect is suppressed. The simulation results show that choosing the right unequal‑teeth proportion greatly improves the machine’s vibration and noise performance over a wide range of operating conditions. The study gives M.Tech students a solid base for exploring advanced stator designs, electromagnetic‑force modulation, and noise‑reduction techniques in electric‑vehicle traction motors.

Project or research direction
This is a source-backed research starting point, not a tested, ready-made student project. Any implementation requires independent feasibility, safety and results verification.
Possible tools or components to evaluate
Finite Element Analysis (FEA) software (e.g., ANSYS Maxwell or JMAG), MATLAB for data processing, CAD modeling tools
Suggested verification steps
- Read the cited paper and check which methods, parameters and results it actually reports.
- Define a measurable project objective and list equipment or software you can access.
- Validate the proposed approach independently before claiming results, working code or experimental success.
Implementation ideas above are planning suggestions, not claims that the cited researchers built or tested those exact extensions.
