IEEE Transactions on Power Delivery, 29(2), 642-650. https://doi.org/10.1109/tpwrd.2013.2272663

Cutting and punching of the electrical steel can cause edge burrs which lead to interlaminar short circuits between the laminations. In this paper, based on an equivalent electric circuit of the eddy current path, an analytical method has been develo...

Investigation of series compensation on dynamic performance of short rotor linear induction motors (2011)
Presentation / Conference Contribution
Hamzehbahmani, H. (2011, September). Investigation of series compensation on dynamic performance of short rotor linear induction motors. Presented at 46th International Universities Power engineering Conference (UPEC2011),, Soest, Germany

Short rotor linear induction motors are a type of linear motors in which the stator is the fixed part and the rotor is the moving part. These linear motors are appropriate to be used in high speed ground transportation and specific industrial applica...
