Design of a Permanent Magnet Linear Generator
2006 International Forum on Strategic Technology, 2006This paper present our experience in the design of a permanent magnet generator. The generator has a long translator and a permanent magnet mover as magnetic field source. It generates a three phase electrical current. The generator is proposed to be operated using a dual chamber free piston internal combustion linear engine. The finished product is to

Cogging force alleviation in linear permanent magnet generators
AFRICON 2009, 2009In this paper a three-phase linear permanent magnet generator is designed for direct waves energy conversion. Its performance is then simulated using analytical and finite element method. Cogging force in this generator causes the oscillatory output power, shortens life time and increases the maintenance cost of the generator.

General Formulation for Magnetic Forces in Linear Materials and Permanent Magnets
IEEE Transactions on Magnetics, 2008A previous work described how a magneto-mechanical tensor can be obtained from the application of the virtual work principle to the energy density or co-energy density in any given media. This paper describes how the volume and surface force densities can be obtained from this tensor.

Reduction of Cogging Force in Linear Permanent-Magnet Generators
IEEE Transactions on Magnetics, 2010Although linear permanent-magnet generators (LPMGs) are widely used for converting wave energy into electrical energy, they suffer from large cogging force. The cogging force causes oscillatory output power, which shortens lifetime and increases the maintenance costs of the generators.

A Tubular Permanent Magnet Linear Generator With Novel Structure
IEEE Transactions on Plasma Science, 2019A single-phase tubular permanent magnet linear generator (TPMLG) with a novel structure for Stirling engines is presented in this paper. TPMLG can directly convert mechanical energy into electrical energy and it is the main energy conversion device in Stirling power generation system. Its 3-D geometry and initial dimensions are given in detail.

Permanent magnet linear generator design using finite element method
International Conference on Electrical, Electronic and Computer Engineering, 2004. ICEEC '04., 2005This paper presents a general proposal to design and calculate the performance of a tubular permanent magnet linear generator using the Finite Element Method. The cogging force, which occurs due to the interaction between stator teeth and the permanent magnets, is reduced by optimizing the linear generator dimensions.

Simulation of Tubular Transverse Flux Permanent Magnet Linear Generator
2018 21st International Conference on Electrical Machines and Systems (ICEMS), 2018Tubular transverse flux permanent magnet linear generator is especially suitable for wave energy conversion because of its special movement forms and high power density. Generator design and optimization rely on finite element simulation tools. However, the existing commercial finite element tools are not friendly supported to the tube-type linear ...

Stator Teeth Model for Optimum Flat Linear Permanent Magnet Generators
2020 International Conference on Sustainable Energy Engineering and Application (ICSEEA), 2020Direct-drive wave energy converter (WEC) with linear permanent magnet generators (LPMG) has been recognized as an efficient system to convert wave energy to electrical energy. However, it suffers from a significant cogging force during its translator movement. Any attempts to reduce the force should also consider the effects on the electrical output as

A ferrite tubular linear permanent magnet generator (FTLPMG) analysis and design
2014 Oceans - St. John's, 2014Several linear synchronous generators for the exploitation of sea wave energy have been proposed. Such machines do not require reactive power for the magnetization since they use permanent magnets for the excitation. The use of permanent magnets in a rough environment such as the marine environment may be a very weak point in the application of these ...

Suitable Configuration of Permanent Magnet Linear Synchronous Generator for Wave Power Generation
2007 Power Conversion Conference - Nagoya, 2007Wave power generation as an alternative energy source should be considered in Japan. Wave power generation has been studied in Japan, but has not been widely applied. The current method of wave power generation has disadvantages, in that the equipment is huge and expensive, because the generator is driven with an air turbine.
