摘要：
This paper investigates a new construction method for the reduction of noise of laminated magnetic structures. One form of the method is to insert damping material between stator laminations having different natural frequencies. The stator laminations with different natural frequencies will tend to vibrate at different frequencies thus shearing the interlaminated damping material. Working the damping material will absorb some of the vibrational energy, which would otherwise be emitted as acoustic noise. The work was directed at the switched reluctance motor, which has been viewed as acoustically noisy. Mathematical models and various prototypes are discussed in detail in the paper to assist others in taking advantages of the method.
