Abstract :
Electronic techniques for controlling acoustic noise and vibration depend on an accurate knowledge of the stator resonant frequency. Analytical models are developed, which allows the calculation of the first several modal frequencies. The impact of the stator stack length on the accuracy of the formulae is also examined. Experimental validation is included
