Abstract :
This research provides a detailed finding of the mechanics of vibration in permanent magnet synchronous motors due to electromagnetic origins. Several fractional slot PM topologies are investigated to quantify the vibration phenomenon that is influenced by motor slot/pole and winding configurations. The research also sorts out the vibration mode order responsible for deformation and the resulting excitation frequency. A finite element based co-simulation in electromagnetic and structural domain is used to find the radial forces and hence the displacement to quantify the vibration/noise performance of these selected motors. The displacement and frequency is converted to sound pressure level to show the relative differences in noise levels among these motor topologies.
