The BDCE equivalent control method for multiphase induction machine

Abstract

The concept behind the brush dc equivalent (BDCE) control method for multiphase induction machine is described in this paper. The BDCE concept is developed from the dc machine operation. A method for calculating the air-gap flux density is given in this paper. Calculated and finite element analysis (FEA) evaluated flux density waveforms for a nine-phase induction machine are provided. Also, a comparison of analytically calculated and measured torque of the machine is given.
