This paper presents a new dual-stator doubly salient brushless DC generator (DSBLDCG). The key of the proposed generator is to reduce the voltage and torque ripples. Finite element analysis (FEA) of the generator is carried out to investigate the magnetic field distribution at different rotor positions. Furthermore, flux-linkage and inductance characteristics are also given. The simulation of the...
This paper presents the design and analysis of a direct-coupled radial-flux permanent magnet generator (PMG) for wind turbine applications. The analysis of the design was carried out using finite-element analysis (FEA). The design data is used in optimizing the configuration and magnetic flux density of the PMG. For evaluating the performance of the proposed PMG, the prototype generator is implemented...
High-speed permanent magnetic generator (HSPMG) is a common and important power generation equipment in distributed generation systems. In this paper, a 100kW level HSPMG is studied, and the transient 2-D electromagnetic field is analyzed by using FEA, from which losses distributions (heat sources), especially eddy loss in rotor sleeve in machines are determined. Then, the 3-D thermal field is calculated,...
The paper presents a single phase, slotless axial flux permanent magnet synchronous machine for induction heating gen sets. A full scale prototype of the machine (110 kVA, 400 Hz, 690 A) has been designed and subsequently analyzed through FEM analysis (FEA). Induced current distributions in the permanent magnets (PMs) and in the rotors are also calculated through FEA and it is seen that the resulting...
The design of 2-dimensional equivalent model for claw-pole type generator is presented in this paper. On the basis of 3D geometry, 2D equivalent model is designed and 2D FEA is performed. Comparing to other analysis method for claw-pole type machine, such as 3D FEA and MEC, presented method can be more practically used and directly applied to industry. Flux distribution in the air-gap and flux density...
