One of the major challenges diagnosing rotor symmetry faults in induction machines (IMs) is severe modulation fault and supply frequency components. In particular, existing techniques are not able to identify components case low slips. this article, problem tackled by proposing a novel approach. First, new use singular spectrum analysis (SSA), as powerful analyzer, introduced for detection. Our...

Most textbooks on electric machines present a classical five-element constant impedance equivalent circuit for modeling polyphase induction machines operating under balanced polyphase sinusoidal steady-state conditions. Yet it is known for cage rotor machines that the rotor element impedances vary significantly with rotor j-equency. Research is in progress to determine a better ac equivalent ci...

Various electric machines can be the candidate for electric vehicles applications, including induction machines, permanent magnet synchronous machines, switched reluctance machines, etc. Another class of machine, which has been relatively ignored, is synchronous reluctance machines. In order to enhance and increase torque density of pure synchronous reluctance machines, the low cost permanent m...
