Summary :
|
|
IN THIS PAPER A SIMPLIFIED APPROACH IS INTRODUCED TO MODEL FORCED VIBRATIONS OF MAGNETIC ORIGIN IN NON-SKEWED ELECTRIC MACHINES. IN THIS APPROACH A 2D FINITE ELEMENT ELECTROMAGNETIC MODEL IS USED TO OBTAIN THE MAGNETIC FORCES AND A 3D STRUCTURAL FINITE ELEMENT MODEL IS USED TO CALCULATE THE VIBRATIONS. THE FORCED VIBRATIONS CALCULATIONS ARE VALIDATED BY MEASUREMENTS. THIS PROCEDURE IS BASED ON THE ASSUMPTION THAT THE TANGENTIAL AND RADIAL COMPONENTS OF THE MAGNETIC FORCES ARE CONSTANT THROUGH THE LONGITUDINAL AXIS IN NON-SKEWED ELECTRIC MACHINES. |
