The Literature Revealed That Fractional Slot Number PMMs Use A Variety Of Magnet Structure Configurations, Including Radial, Parallel, And Hybrid Arrangements. Different Magnet Configurations Were Discovered To Affect The Distribution Of Magnetic Flux Density, Thereby Impacting UMP Concentrations. The Effect Of Various Magnet Geometries, Including Arc, Rectangular, And Trapezoidal, On UMP Was Examined. Moreover, The Selection Of Magnet Materials, Such As Ferrite, Neodymium-Iron-Boron, And Samarium-Cobalt, Influenced The Magnetic Field Distribution And UMP Characteristics.Due To Their Particular Slot And Pole Combinations, Fractional Slot Number PMMs Were Found To Be More Susceptible To UMP Than Other PMM Varieties. Unbalanced Forces Caused By UMP Resulted In Unwanted Vibrations, Increased Noise Levels, And Possible Machine Durability Issues. Numerous Factors Influence UMP In Fractional Slot Number PMMs, Including The Number Of Slots And Poles, The Length Of The Stator-Rotor Air Gap, The Magnet Pole Breadth, And The Magnet Thickness. The Level Of UMP Was Affected By The Interaction Of These Factors With Magnet Structure Configurations. DOI: 10.59762/cie570390542120240205132702
