This paper illustrates a design methodology to accomplish optimum performance for a single-phase, tubular, linear permanent magnet generator which drives linear motion of wave energy for Wave Energy Conversion (WEC) system application. It is shown that the linear generator performance can be optimized with respect to three leading dimension ratios. Existence of copper loss in the linear generator also can be reduced by performing the optimization process. Results for the linear generator efficiency, copper loss and output power are demonstrated and discussed are shown to be as expected.

This paper proposes a permanent magnet single-phase linear generator (PMSPLG) with Halbach PM Array applied in wave energy conversion system and illustrates how the parameter changes in the geometry of permanent magnet and slot affect the cogging force of the generator. Moreover, the cogging force analysis method in PMSPLG is improved based on the cogging torque analysis method of permanent magnet synchronous rotation machine. Due to experiment results of prototype concordant with the analysis results of the analytical method and the finite-element method, the proposed model and analytical method are correct and effective.

This study aims to observe the influence of the changing stator dimension on the air gap magnetic flux density (Bg) in the design of a single-phase radial flux permanent magnet generator (RFPMG). The changes in stator dimension were carried out by using three different wire diameters as stator wire, namely, AWG 14 (d = 1.63 mm), AWG 15 (d = 1.45 mm) and AWG 16 (d = 1.29 mm). The dimension of the width of the stator teeth (Wts) was fixed such that a larger stator wire diameter will require a larger stator outside diameter (Dso). By fixing the dimensions of the rotor, permanent magnet, air gap (lg) and stator inner diameter, the magnitude of the magnetic flux density in the air gap (Bg) can be determined. This flux density was used to calculate the phase back electromotive force (Eph). The terminal phase voltage (V∅) was determined after calculating the stator wire impedance (Z) with a constant current of 3.63 A. The study method was conducted by determining the design parameters, calculating the design variables, designing the generator dimensions using AutoCad and determining the magnetic flux density using FEMM simulation.  The results show that the magnetic flux density in the air gap and the phase back emf Eph slightly decrease with increasing stator dimension because of increasing reluctance. However, the voltage drop is more dominant when the stator coil wire diameter is smaller. Thus, a larger diameter of the stator wire would allow terminal phase voltage (V∅) to become slightly larger. With a stator wire diameter of 1.29, 1.45 and 1.63 mm, the impedance values of the stator wire (Z) were 9.52746, 9.23581 and 9.06421 Ω and the terminal phase voltages (V∅) were 220.73, 221.57 and 222.80 V, respectively. Increasing the power capacity (S) in the RFPMG design by increasing the diameter (d) of the stator wire will cause a significant increase in the percentage of the stator maximum current carrying capacity wire but the decrease in stator wire impedance is not significant. Thus, it will reduce the phase terminal voltage (V∅) from its nominal value.
