Abstract:
|
This paper presents a new approach for the current acquisition system in motor fault detection applications. This paper
includes the study, design, and implementation of a Rogowski coil current sensor without the integrator circuit that is typically used. The circuit includes an autotuning block able to adjust to different motor speeds. Equalizing the amplitudes of the fundamental and fault harmonics leads to higher precision current measurements.
The resulting compact sensor is used as a current probe for fault detection in induction motors through motor current signal
analysis. The use of a Rogowski coil without an integrator allows a better discrimination of the fault harmonics around the third and
fifth main harmonics. Finally, the adaptive conditioning circuit is tested over an induction machine drive. Results are presented, and quantitative comparisons are carried out. |
