“…The two essential parts of a linear generator are the stator and the translator. The stator consists of three-phase windings and a nonlinear magnetic core, while the translator consists of a shaft with permanent magnets, each separated by nonlinear magnetic materials [1,2,14]. This study investigates the electromechanical characteristics of two types of three-phase linear generators, the TPLG-6 and the TPLG-18.…”

“…Linear generator with radial permanent magnets is a well-known sea wave energy converting device, providing high linear force and efficiency [5]. In order to extract this massive sea waves energy, various Wave Energy Converter (WEC) devices have been proposed, such as Archimedes Wave Swing (AWS), LIMPET, Pelamis, Wave Dragon and Electroactive Polymer Artificial Muscles (EPAM) [6,7,10,11,16]. However, most of these devices were offshore, leading to high maintenance costs.…”

The motion of sea waves can be converted into electrical energy using a three-phase linear generator. This paper investigates the electromechanical characteristics of two types of the three-phase linear generator, namely TPLG-6 and TPLG-18. The electromechanical characteristics such as power, efficiency, torque, d-q axis synchronous inductance, saliency ratio and current are investigated. MATLAB Simulink is used for the simulation. In this study, the d-q synchronous inductance is calculated to investigate the effects of d-q synchronous inductance on the permanent magnet. The Maximum Torque Per Ampere (MTPA) is plotted to determine the torque required to generate the maximum d-q current. The saliency ratio will also be investigated by comparing the d-q synchronous inductance for TPLG-6 and TPLG-18.

“…First, the flux distribution is simulated using FEMM software. The flux magnitude per magnet is [55] ∅ PM,pk = 2B m,pk π h yr + h m τ p (11) φ PM,pk is the peak flux magnitude resulted from a magnet (Wb), and B m,pk is the peak permanent magnet flux density (T). The flux flows are shown in Figure 10.…”

Performance of Linear Generator Designs for Direct Drive Wave Energy Converter under Unidirectional Long-Crested Random Waves

For generating electricity, direct-drive wave energy converters (WECs) with linear permanent magnet generators (LPMGs) have advantages in terms of efficiency, simplicity, and force-to-weight ratio over WEC with rotary generators. However, the converter’s work under approaching-real wave conditions should be investigated. This paper studies the performance of a pico-scale WEC with two different LPMGs under unidirectional long-crested random waves. Different significant wave heights (using data in the Southern Ocean of Yogyakarta, Indonesia) and peak frequencies are tested. The JONSWAP energy spectrum is used to extract the wave elevations, while the MSS toolbox in MATLAB Simulink is employed to solve the floater’s dynamic responses. Next, the translator movements are extracted and combined with the flux distribution from FEMM simulation and analytical calculation, and the output powers are obtained. An experiment is conducted to test the output under constant speed. The results show for both designs, different tested significant wave height values produce higher output powers than peak frequency variation, but there is no specific trend on them. Meanwhile, the peak frequency is inversely proportional to the output power. Elimination of the non-facing events results in increasing output power under both parameters’ variation, with higher significant wave height resulting in a bigger increase. The semi iron-cored LPMG produces lower power loss and higher efficiency.
