N2 - This paper reports on the magnetic field distribution and magnetic circuit calculating method of micro generator. A micro axial-flux electromagnetic generator is designed as size of Φ6mm×3mm. Traditional magnetic circuit analysis methods are used to retrieve the air-gap magnetic density on no-load micro generator in operation. FEA is done for the micro generator model using magnetic field numerical simulation software. The main parameters of no-load magnetic field and the waveform of induced EMF are obtained. Comparing the results obtained from the magnetic circuit analysis and numerical simulation, the error of air magnetic density is less than 2.54% and the error of the maximum value of induced EMF is less than 2. 68%. The results suggest that magnetic circuit analysis methods can be used for magnetic field analysis of micro axial-flux electromagnetic generators, and be helpful to provide guidance for designs.
