Tubular Linear Induction Machine as a Fast Actuator: Analysis and Design Criteria
نویسندگان
چکیده
In this paper, some design criteria for a Tubular Linear Induction Motor (TLIM) as a fast actuator are considered. The influence of geometrical and physical parameters on the operating conditions of a TLIM are investigated by means a quasi-analytic model. The model is based on the application of the Fourier Transform both in space and in time. The Fourier transform in space is introduced to take into account the finite length of the stator windings in the axial direction. The transient electrical response of the motor at standstill following the insertion of a three-phase system of voltage generators is performed by the Fourier transform in the time.

متن کاملAnalysis of the Frequency Effects on Design and Back-Iron Characteristics of Double-Layer Secondary Single-Sided Linear Induction Motors
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...
