Abstract
The optimization design of high-speed permanent magnet generator used in micro turboj et engine (MTE)is studied in this paper.The traditional finite element simulation method is too complex in the calculation of the back EMF and inductance.In order to solve this problem,a finite element simulation model of motor based on slip boundary condition is proposed by combining the slip boundary method with finite element analysis.On this basis,combining the calculation of electromagnetic parameters based on the slip boundary finite element model with the gradient descent optimization method,this paper proposes an improved gradient optimization algorithm,aiming at optimizing the design for the minimum volume of generator.Based on the above optimization results,several high-speed generator prototypes for MTE are designed,and the validity of the proposed method is verified by testing their electromagnetic parameters.关键词
