Analysis and Optimization of a Tubular Permanent-Magnet Linear Generator

2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019
In the paper, a tubular permanent-magnet linear generator (TPMLG) is designed and analyzed. The key of the proposed machine is to adopt a mover structure with the quasi-Halbach PM array to meet the strict limit of mover weight and electromagnetic performances.

General Formulation for Magnetic Forces in Linear Materials and Permanent Magnets

IEEE Transactions on Magnetics, 2008
A 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.

A Tubular Permanent Magnet Linear Generator With Novel Structure

IEEE Transactions on Plasma Science, 2019
A 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.

Cogging force alleviation in linear permanent magnet generators

AFRICON 2009, 2009
In 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.

Reduction of Cogging Force in Linear Permanent-Magnet Generators

IEEE Transactions on Magnetics, 2010
Although 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 ferrite tubular linear permanent magnet generator (FTLPMG) analysis and design

2014 Oceans - St. John's, 2014
Several 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 ...
