The performance of the proposed method deals with the emerging technique called as Motor Current Signature Analysis (MCSA) and the Zero-Sequence Voltage Component (ZSVC) to diagnose the stator faults of Induction Motors. In other words, it measures the magnitude of the flux for the number of turns in an electric circuit. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. The proposed winding layout is based on dual two-phase windings shifted in space by 450 electrical degrees to completely cancel out both the third and fifth order harmonics. A Linear Induction Motor (or LIM) is a special type of induction motor used to achieve rectilinear motion rather than rotational motion as in the case of conventional motors. Continue Reading.
