“…The keyword extraction results align with our analysis in Section 3.1 , with wind ranking the highest. Hydrogen production also appears to be relevant in the M2 applications, with five papers [ 48 , 51 , [53] , [54] , [55] ] mentioning the possibility of using renewable energy produced at a MUP for hydrogen production. Most M2 applications in the reviewed literature share characteristics with M1 applications, such as focusing on oil and gas platforms, but the literature highlights the synergy of renewable and initial explorations of multifunctionality energy at these platforms.…”

“…To this end, we developed three different models to improve the original configuration of a transverse flux linear induction motor (TFLIM). We include different geometric changes to obtain an LIM where longitudinal and transverse magnetic fluxes can simultaneously operate [6][7][8][9]. Primarily, they are necessary for two relevant changes in the initial geometry.…”

This paper delves into the knowledge of transverse flux linear induction motors using three-dimensional finite element simulation tools. Original linear induction motors have a useful magnetic flux perpendicular to the movement. We propose some geometric changes to improve the main magnetic circuit of the machine and to ensure simultaneous operation between longitudinal and transverse magnetic fluxes. To obtain the main parameters of the equivalent electrical circuit in a steady state, we propose two steps. Firstly, replicate the classic indirect tests used in rotating machines. This represents a significant advantage since it allows several models to be experimentally tested to obtain the values of electrical parameters. Secondly, use the data from these tests to solve a particular system of equations using numerical methods. The solution provides the electrical elements necessary to generate the equivalent circuit proposed by the authors. A quantitative analysis of the main electrical parameters is also carried out, confirming the advantages of the changes introduced. With them, a significant improvement in thrust force is obtained, especially in stationary conditions and low speeds. Finally, we study, in detail, a set of specific phenomena of linear machines using two parameters: the secondary equivalent air gap and the secondary equivalent conductivity.

“…In [15] authors also use FEM-3D to compare the transverse edge effect between various secondary cage configurations. Particularly, in [16] and [17] authors indicate the progressive relevance of TFLIM in the high-speed magnetic levitation transport system, where a mathematical model is used to describe the induced eddy currents. Finally, in [18] Transverse Flux Linear Motor with permanent-magnet excitation is also studied with FEM-2D techniques.…”

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.INDEX TERMS Air gap magnetic flux density, equivalent circuit, goodness factor, indirect tests, magnetizing inductance, transverse flux linear induction motor.
