“…Compared to the first type of tubular LPMG, the flat-type LPMG could generate slightly higher output voltage and specific power for equal loads [5]. Furthermore, the previous investigation has found that the quasi-flat type produces slightly higher flux density as well as induced voltage than the flat-tricore LPMG [6]. The configurations of these types are shown in Figure 1 and Figure 2.…”

Linear permanent magnet generator (LPMG) is an essential component in recent wave energy converter (WEC) which exploits wave’s heave motion. It could be classified into tubular-type, flat-tricore type, and quasi-flat type. In previous researches, these three models have been studied and designed for pico-scale WEC. Design optimization has further been conducted for flat-tricore LPMG, by using simulated annealing (SA) algorithm. It modified some parameters to minimize the resulted copper loss. This paper aims to optimize a quasi-flat LPMG design by applying SA algorithm. The algorithm would readjust the initial LPMG parts dimension. Then, the output of the optimized design would be analyzed and compared. The results showed that the optimization could reduce the copper loss by up to 73.64 % and increase the efficiency from 83.2 % to 95.57 %. For various load resistances, the optimized design also produces larger efficiency. However, the optimized design has a larger size and produces larger cogging force than the initial design.

“…Thus, based on the classification of the working principle, WAB is the most suitable device principle due to the small size and simple design of WAB. The device, according to this principle, precisely, point absorber, has the potential to be developed as portable pico-scale electricity [13,14]. Point absorber is a floating structure device that has fixed buoy inside a cylinder that rises and falls with the differences in wave height [15] and has horizontal dimensions that are smaller than the wavelength of the wave.…”

“…Even though the rotary generator is mostly used for power generation mainly due to its mature technology, however, advancement in direct drive linear machine design is a linear generator. Until now, the research regarding portable linear generator is still under the study [13,19,20]. The basic concept of the linear generator requires a translator with the magnet, which reacts like a rotor [21].…”

Wave energy is one of the renewable resources with high availability area of the wave across the world. However, the wave power density in Malaysia is smaller compared to other countries with progressive development in Wave Energy Converter (WEC), which leads to wave energy utilization to produce pico-scale power generation for the benefit of outdoor activities. Thus, this paper is presenting the modeling of a tubular longitudinal permanent magnet linear generator for wave energy conversion for outdoor activities. This research aims to design a pico-scale linear generator with 100 W output power utilizing wave energy. The design is also intended to be a portable design with a weight that less than 20 kg, which compatible with outdoor activities. The generator is proposed by designing the different shapes of permanent magnets with slotless configuration. The designs are simulated using the Finite Element Analysis (FEA) to obtain the performance of flux distribution, flux linkage, and back EMF performance.
