Abstract

Abstract:

The equivalent magnetic circuit method for designing the high speed permanent magnet generator to obtain the basic parameters of the electromagnetic preliminary designing is detailed. A comparison is made between the different number of slots and the different number of poles, and choosing the right solution .The rule between voltage regulation and the machine parameters is analyzed. The methods of reducing the voltage regulation of are proposed, and determined the reasonable range of the relevant parameters. By using Taguchi optimization design method to establish the matrix of orthogonal experiment, for optimization design, combined with the finite element method is used to solve the matrix, to meet the generator performance optimal combination of design parameters. The finite element method is used to analyze the performance of the design scheme of the permanent magnet generator. The results show that the design scheme is reasonable.

Key words: High speed permanent magnet generator, electromagnetic design, voltage regulation, Taguchi method, finite element method
