Abstract

This paper is focused on the development of a multiphase fault tolerant BLDC machine, oriented towards the stator windings, number of phases and commutation sequences. As a first step, a six-phase BLDC machine will be modeled and simulated, using JMAG-studio software, for no-load regime. The induced emfs, cogging torque, magnetic field density map and distribution will be processed. The results of simulation, in terms of induced emfs, will give the possibility to develop, in the second step, the commutation sequences in order to get optimal torque quality.
