| Abstract |
The asynchronous motor has an interest in
strong powers applications requiring speed variation. Even
if it is robust, it is not saved by electrical or mechanical
defects.
Among rotor defects, we can quote a fissure or a total break
of bar, a rupture of end ring circuit, an eccentricity of the
rotor axis...
In this paper, we use a technique based on the spectral
analysis of stator current in order to detect a breakdown or
a defect in the rotor. Thus, the number and the position
effect of the breaks have been highlighted.
The effect is highlighted by considering the machine
supplied directly through a balanced three-phase network. |
