Tangential Permanent Magnets In High Pole Number Permanent Magnet Alternator
Abstract: The objective of the invention is to increase the output power of permanent magnet alternator having high number of poles. The air gap flux density in permanent magnet generator can always be improved by designing optimized rotor configuration such that the total reluctance in the magnetic flux path is minimum. A new rotor structure which comprises of tangential permanent magnets and appropriate holes is proposed. A comparison study is carried out analytically between proposed rotor configuration and existing rotor configuration for same volume of rotor and permanent magnets. The objective is to show the increase in power density with the proposed rotor configuration compared to the existing rotor configuration. The analytical study is validated with FEM software and the results are presented.
