چکیده
Field Analysis and Design of a Moving Iron Linear Alternator for Use with Linear Engine Dulpichet Rerkpreedapong The previous research at West Virginia University has developed a permanent magnet linear alternator and linear combustion engine for testing and studying the performance. In this prototype, magnets are part of the moving part. This research will present a new type of linear alternator with permanent magnets installed on stationary called Moving Iron Linear Alternator (MILA). MILA offers several advantages over other types such as rugged structure, and low cost production. First, MILA will be designed for use with the existing linear engine. An optimization methodology will be applied to obtain optimal design parameters. Next, a MILA model will be created in EMAS, field analysis software, to determine the machine flux. Later, the simulation will be performed for calculating the back emf and current of MILA. Finally, the simulation results will be discussed and explanations will be given.

Input frequency is one of the important variables in design and performance analysis of single-sided linear induction motors (SLIMs). Changing the frequency changes both the dimension of the SLIM in design process and the performance of the designed motor. The frequency influences the induced eddy currents in the secondary sheet as well as saturation level of the secondary back-iron. In this pa...
