Calculation and Experimental Determination of Inductance Parameters of Brushless Double Fed Machine for Magnetic Barrier Rotor

Abstract

Brushless doubly fed machine (BDFM) is a new type of AC motor, which has the advantages of brushless reliability and low cost. The inductance parameters of this kind of motor are relatively complex, and the inductance parameters are the basis for motor performance analysis and high precision control. In this paper, the inductance parameters of the motor are calculated by finite element analysis method, along with the experimental prototype is developed to measure the inductance parameters. The correctness of the theoretical analysis is proved, which provides useful reference for the high precision control of BDFM.
