“…Hence, due to repeated compression-expansion of the engine cylinders and constant application of motoring force in the direction of natural bouncing motion, the amplitude and speed of the translator are expected to grow due to mechanical resonance. The TPMLG is the energy generation device in the FPLG, and thus, its appropriate selection at the conceptual design stage is crucial [3]. The Free piston internal combustion engines offer better dynamic profiles and can work at variable compressed ratio as well as has a less pollution.…”

“…The main problem concerning in electric vehicles is the performance of the batteries for the electric power storage system. Therefore, there are several solutions used to combine the power generated by the combustion engine and the electric motor inside a hybrid electric vehicle namely, parallel hybrid, series hybrid and parallel-series hybrid [3]. Notably, most of the systems use rotating generators and engines, therefore, linear electric generators connected directly to free piston engine is a viable solution.…”

“…When the linear engine is made as a platform to convert mechanical to electrical energy through a particular arrangement of a linear generator for portable power generators for commercial and domestic use [4,5]. Moreover, during the combustion stroke, the expansion of the free piston is faster compared with a conventional engine and the time spent around the TDC is shorter, meaning the speed is also higher around TDC [2,3]. Figure 1 shows the cross-section of the major components of FPLG.…”

Abstract. Generating power is of great importance nowadays across the world. However, recently, the world became aware of the climatic changes due to the greenhouse effect caused by CO2 emissions and began seeking solutions to reduce the negative impact on the environment. Besides, the exhaustion of fossil fuels and their environmental impact, make it is crucial to develop clean energy sources, and efforts are focused on developing and improving the efficiency of all energy consuming systems. The tubular permanent magnet linear generators (TPMLGs) are the best candidate for energy converters. Despite being suffering problem of attraction force between permanent magnets and stator teeth, to eliminate such attraction force, ironless-stator could be considered. Thus, they could waive the presence of any magnetic attraction between the moving and stator part. This paper presents the design and analysis of ironless -cored TPMLG for low grid power generation. The main advantages of this generator are the low cogging force and high efficiency. Therefore, the magnetic field computation of the proposed generator has been performed by applying a magnetic vector potential and utilizing a 2-D finite element analysis (FEA). Moreover, the experimental results for the current profile, pressure profile and velocity profile have been presented.
