“…The operation of the Stirling engine may be understood by considering its fixed volume and fixed heat states. The Stirling engine has four states (Figure 2): the process between states 3 and 4 occurs at fixed temperature when heat is drawn from the operating gas; the process between states 4 and 1 when giving heat to the operating gas from an external source; the process between states 1 and 2 occurs when the operating gas expands and moves the piston at fixed temperature; the process between states 2 and 3 process ends in conversion and the heat in fixed volumes should be removed from the operating gas [10–12, 22, 43–53].…”

An alternative way to generate electricity from solar energy is through the use of generators comprising Stirling engines with a parabolic collector. This study describes a parabolic collector with Stirling engine and investigates the design of a linear mobile generator for these systems. Especially for direct drive in free piston mechanisms proposed for these systems, linear generators are important due to their advantages such as compact structure, light weight, high efficiency and high power intensity. Although conventional one‐phase and three‐phase multi slot/pole models are widely available in the literature, three phase is considered for lower PM cost and to reduce the cost of power electronics and 3/2 slot/pole combination is considered for high speed and frequency. In this study, a new 3/2 slot/pole three‐phase tube‐type linear generator was designed and evaluated for performance and manufacturability. Objective functions were defined for power and efficiency increase to reduce generator power ripple, and the results of Mixed‐Integer Sequential Quadratic Programming, Multi‐Objective Genetic Algorithm (MOGA), and Screening methods were compared and examined. Performance of the two‐dimensional and optimized models was evaluated in terms of induced voltage, power density, efficiency, and output power. The best results were found with MOGA compared to other methods. When compared with the initial value, there was a 97.3% increase in power density for a 32.4% increase in moving weight. Moreover, the efficiency of the MOGA model is improved by 16.2% compared with the initial model. Additionally, significant improvements were shown in terms of thrust coefficient, voltage coefficient, power, and no‐load voltage. A prototype of the model was made and a motor‐driven crank mechanism system was used in place of the Stirling engine to undertake practical measurements.

In this study, design of tube type linear generator, which can generate electricity from suspension systems of electrical vehicles, has been realised. Information about widely-used suspension systems has been given and advantages and disadvantages of linear type electro-magnetic dumpers have been mentioned. Analytic design of tube type linear generator has been made for passive suspension system. In line with obtained sizing parameters, numerical analyses have been made in Ansys-Maxwell programme and results of such analyses have been examined. Prototype of analyzed tube type linear generator has been made. Measurements of magnetic flux density and simulation results in air gap have been compared. The linear generator designed has been applied for passive suspension. The experiments of the linear generator with 20, 40, 60, 80, 100, 120 and 130 mm stroke length were performed, respectively. During the experiments, a frequency range of 1 Hz to 5 Hz was chosen. The highest speed was 1,3 m/s and the generated pk-pk voltage value was 37.7 volts. The speed value of the generator changes according to the road condition. Therefore, a converter is needed for battery charging after the generator output voltage is rectified.
