Resumos Cadastrados

Resumo Inglês:

This paper presents measured data and electromagnetic
FEM field calculations as techniques for detecting and analyzing
eccentricity in three-phase induction motors. Also it presents
experimental results for detecting broken bars in induction motor
rotors. A search-coil is used as magnetic field sensor to measure the
stray magnetic flux outside the motor. It is a totally non-invasive
method.
