This paper aims to develop a small permanent magnet (PM) synchronous generator for direct-coupled, low-speed wind turbine applications. The generator, rated 3-phase 110 V and 1 kW is designed as an outer rotor structure. The design and optimization of the generator is done with the aid of the electromagnetic field analysis based on the finite element method.

Design Requirements

This paper uses ANSYS 10.0 software to analyze and calculate electromagnetic field of the Permanent Magnet Synchronous Generator(PMSG). Verify rationality of magnetic circuit by the results of magnetic flux density and magnetic field intensity; optimize shape of permanent magnet and reduce harmonics quantity by air-gap flux density harmonics analysis, and use value to solve Electromotive Force(EMF). The simulation result proves that the model satisfies the design requirements and can provide theoretical guide for the optimization design of PMSG.

Force Characteristics

Several constructions of electromagnetic actuators with moving permanent magnet for Braille screen are studied. All they are formed from a basic one that consists of two coils, core and moving permanent magnet. The finite element method is used for modeling of the magnetic field and for obtaining the electromagnetic force acting on the mover. The static force-stroke characteristics are obtained for four different constructions of the actuator. The constructions with ferromagnetic disc between the coils ensure greater force than the ones without disc and can reach the required minimum force.

The aim of the work is precise coupled –electromagnetic and temperature field analysis of an induction heating system by finite element method. Presented example is referred to real induction heating system. The problem was solved as nonlinear, transient and axisymmetrical. The numerical model of the coupled fields is based on the finite element method and electromagnetic and temperature distributions have been obtained using COMSOL 3.3 software package.
