    A 3-D Simulation of a Single-Sided Linear Induction Motor with Transverse and Longitudinal Magnetic Flux
    (MDPI, 2020) Domínguez Hernández, Juan Antonio; Duro Carralero, Natividad; Gaudioso Vázquez, Elena; https://orcid.org/0000-0002-6437-5878
    This paper presents a novel and improved configuration of a single-sided linear induction motor. The geometry of the motor has been modified to be able to operate with a mixed magnetic flux configuration and with a new configuration of paths for the eddy currents induced inside the aluminum plate. To this end, two slots of dielectric have been introduced into the aluminum layer of the moving part with a dimension of 1 mm, an iron yoke into the primary part, and lastly, the width of the transversal slots has been optimized. Specifically, in the enhanced motor, there are two magnetic fluxes inside the motor that circulate across two different planes: a longitudinal magnetic flux which goes along the direction of the movement and a transversal magnetic flux which is closed through a perpendicular plane with respect to that direction. With this new configuration, the motor achieves a great increment of the thrust force without increasing the electrical supply. In addition, the proposed model creates a new spatial configuration of the eddy currents and an improvement of the main magnetic circuit. These novelties are relevant because they represent a great improvement in the efficiency of the linear induction motor for low velocities at a very low cost. All simulations have been made with the finite elements method—3D, both in standstill conditions and in motion in order to obtain the characteristic curves of the main forces developed by the linear induction motor.

    Simulation of a Transverse Flux Linear Induction Motor to Determine an Equivalent Circuit Using 3D Finite Element
    (IEEE, 2023) Domínguez Hernández, Juan Antonio; Duro Carralero, Natividad; Gaudioso Vázquez, Elena; https://orcid.org/0000-0002-6437-5878
    This paper presents a Transverse Flux Linear Induction Motor prototype simulated with a 3D Finite Element tool. The main objective of the paper is to obtain an accurate method to construct an equivalent circuit that simulates the motor, using some specific parameters. The method has three steps. In the first step, we simulate two indirect tests to represent rotating induction machines, standstill and locked rotor tests. Using the test results, we define an equations system that incorporates the longitudinal end-effect. The system allows us to select specific parameters needed to build the equivalent circuit using six different configurations. In the second step, we classify the parameters in two groups: parameters from the primary and secondary parts. We test the primary part parameters defining the magnetizing inductance as a combination of the longitudinal and the transversal magnetizing inductance. To this end, the method analyses the first harmonic of the magnetic field wave along the air gap, which is located above the central teeth. Thus, it is possible to establish a difference between transversal and longitudinal components of the magnetic field density. The parameters of the secondary part will be compared using 2D Field Theory with a linear induction motor that operates with a transverse flux configuration. In the third step, the method analyses the selected parameters using a goodness factor, a dimensionless key performance indicator, specifically used to evaluate the behavior of linear induction motors and the specific parameters estimated for the equivalent circuit.
