This paper investigates motor vibrations due to reluctance forces. Forcing frequencies caused by motor design, part geometries, and errors in assembly are tabulated for several popular pole/slot ratios. Motor torque and translational force fluctuations are found to exhibit a rich set of shapes and frequencies, especially when multiple defects occur simultaneously. Two analysis methods are employed: the FEA approach and the Convolution Method. Both techniques predict similar frequency spectra… CONTINUE READING
