High-speed permanent magnetic generator (HSPMG) is common and important power production equipment in distributed generation systems. According to the structure characteristics of a 100kW level HSPMG, the mathematical model and physical models for its two-dimensional electromagnetic and thermal analyses are established, and the electromagnetic field of generator working in steady state is calculated...
This paper presents a general technique to analyze thermal behavior of direct-drive permanent magnet (DDPM) wind generator. Both lumped parameter network (LPN) and finite element method (FEM) are used in this technique to predict the temperature distribution of a 2 MW DDPM wind generator. This technique is then validated after experimentation carried out on a 10 kW prototype equipped with thermal...
This paper presents the thermal design aspect of linear generator. A study is carried out to investigate the temperature effects on the components in linear generator. One of the most important components in the linear generator, neodymium Iron boron (Nd-Fe-B) permanent magnet is emphasized in this study since it provides a magnetic field source for the linear generator and the influence of its electromagnetic...
