| Abstract |
The aim of this contribution is the investigation of the influence of load torque on rotor fault
specific effects. An asymmetric rotor cage causes sideband currents and shaft torque modulations
which depend on the actual load state. In general, these are well known phenomenas. While their
frequencies moves with the actual slip, amplitudes and phase angles show non linear dependencies.
These dependencies will be investigated and analyzed. Simulation and measurement results are
presented.
This paper deals with the Vienna Monitoring Method (VMM), too. The VMM is based on
the comparison of calculated torque values which are obtained from two different mathematical
machine models. The impact of load torque on the VMM will be investigated. |
