“…11 shows thrust force evolution on the vehicle as it travels from position x 1 = 1 cm to x 1 = 35 cm, with 7 A in the magnetic circuit. When the vehicle is located at interval [1,2] cm, thrust force is highly penalized by the opposite force acting on surface b. During the central interval [2,3] cm, thrust force is nearly constant, reaching its maximum value.…”

“…When the vehicle is located at interval [1,2] cm, thrust force is highly penalized by the opposite force acting on surface b. During the central interval [2,3] cm, thrust force is nearly constant, reaching its maximum value. Into this interval, force on surface b acting in the opposite direction to vehicle movement is now almost null because surface b is now out of the air gap.…”

A new YBCO superconducting linear propulsion system that uses the Meissner effect for thrust is proposed. A YBCO bulk is used in the vehicle, which is excited synchronous with a magnetic field traveling wave. The propulsion system's model is developed using a magnetic circuit method and the Maxwell stress tensor analysis. The vehicle acceleration and thrust force characteristics previewed from that model are verified and analyzed by practical measurements and a set of essays using the prototype built in our laboratory. Major errors came for thermally activated flux creep and current conduction in the YBCO during its passage through the excitation system. The total magnetic field at the superconductor's surface decreases, reducing thrust force. Despite these secondary effects, achieved results show the potential of this new approach for future electric propulsion systems.

“…The slot and end effects of LPMSMs can be accounted for by the magnetic equivalent circuit (MEC) which is widely used due to its simplicity and fast computation [12][13][14][15][16][17]. In [13], a relatively simple and accurate MEC model is proposed for LPMSMs and the air gap flux density distribution is obtained by linear interpolation of flux densities at specific mover positions.…”

Abstract-This paper presents an improved analytical subdomain model for predicting the magnetic field in linear permanent magnet synchronous machines (LPMSMs) with semi-closed slots accounting for the finite length of primary iron core and secondary back-iron. The whole field domain is divided into eight subdomains and the magnetic field in each subdomain is solved by applying the variable separation method, adequate boundary conditions and interface conditions. In this model, both the slot and end effects are considered. The thrust and normal forces are calculated by the Maxwell stress theory. The finite element analysis is carried out to validate the analytical model. Finally, an LPMSM prototype is manufactured and tested. The experimental results show that the developed analytical model has high accuracy for predicting the magnetic field and forces.Index Terms-Linear PM machines, improved analytical model, slot effect, end effect.

The cylindrical linear electromagnetic pulsing motor (EMPM) is an alternative electric vehicle (EV) to be simulated in this study. The proposed design on the cylindrical linear EMPM will replace the piston engine in an internal combustion engine (ICE) which produces linear motion. It can eliminate problems related to internal combustion engines (ICE) such as engine weight and friction where fewer components have been used. In this paper, an analytical model was constructed and predicted the magnetic equivalent circuit (MEC) that can solve with the same technique as the electrical circuit. The initial magneto-statics analysis was conducted through the finite element magnetic software (FEMs) for magnetic filed problem so that the magnetic flux relationship could be predicted. Furthermore, the FE modelling and analysis is followed by a MATLAB/Simulink software calculation to predict the cylinder linear EMPM. Finally, the simulation results of the FE models regarding plunger force, thrust, plunger distance, speed, and power motor were presented and compared with the regulated counterparts obtained from the experimental setup.
