“…Therefore an automated design process and recalculation is necessary to do an optimization of the whole system. There is similar work about design, modeling and optimization of linear machines of different types, especially of induction machines [5]- [8]. But the idea to examine the complete coupled system under the aspect of joint optimization targets seems to be new.…”

This paper describes the design process of a tubular linear synchronous machine. The design steps include all important parts without some special effects like iron losses. The description of the process is done that the reader becomes informed about all necessary steps for automation taking into account a surrounding optimization loop. The optimizer needs several results from the design, to improve its values. Therefore the design is completed by a description of analytical formulations necessary to compute important values like force and mass. Within this paper it becomes clear that there is no big difference between the well known formulations of rotational machines and linear machines. Therefore this paper helps to understand the automated design process of a linear machine and the differences and changes to rotational machines. Special results and graphs are not added to this paper, as the results of the automated design process depend on the target function of the optimizer.

“…Recently, tubular linear permanent magnet (TLPM) machines have been investigated for many applications. Because there are no end windings in TLPM and its permanent magnet (PM) material utilization ratio is high, the thrust force density of TLPM machines are found to be very favorable when compared with its linear counterparts [1].…”

This paper proposes a novel linear permanent magnet machine for direct drive applications in which a magnetic gear is ingeniously integrated with a tubular linear machine, aiming at improving the thrust force density and enhancing the machine efficiency. The operating principle of the proposed machine is introduced. An optimal design with reduced cogging torque, improved thrust force density, and enhanced power factor is presented and discussed. By using circuit-fieldmotion coupled time-stepping finite element method (FEM), the steady-state as well as transient performances of the machine are simulated. The FEM computation results are consistent with theoretical analysis, hence verifying the validity of the machine design.

“…The marine environment, by its very nature, would cause a sharp deterioration in the mechanical parts, arising the need of continuous maintenance and resulting in increased costs. Among linear machine, tubular linear generators achieve the highest power density [15]. Tubular generators are of a very easy construction and their windings have no end connection.…”

Sea waves are one of the most interesting and well distributed renewable energy sources in the world. At the current state of the art, several devices have been proposed for wave power exploitation and some have been commercialized. The Inertial Sea Wave Energy Converter is a wave energy converter composed of a floating body slack-moored to the seabed using a gyroscope as a reference frame to produce electric power. In this work the gyroscopic wave energy converter is equipped with two linear tubular generators exploiting the reciprocating movement between the gyroscopic system and the hull to generate power. The linear generators are designed for a 3 kW device. Experimental tests on a small scale prototype are performed
