Abstract:
|
The purpose of this paper is to present a new model to study intern-turn short circuit faults in a dynamic
loudspeaker. The loudspeaker is modeled by using classical voice coil parametric model attached to a mechanical
piston, and the equations are modified to take into account the voice coil inter-turn faults. The loudspeaker model is
global and can work in both normal and fault conditions due to a fictitious resistance in the winding circuit. Various
simulation results have been presented indicating the fault instant in time and its corresponding effect in power
spectral density. The model can serve as a step towards development of fault detection and diagnosis algorithm. |
