Finite Element Analysis Of A Novel Brushless DC Motor With Flux Barriers

The paper describes the finite-element modelling of a novel form of brushless d.c. machine, which is of the interior magnet type, and uses radial flux barriers in the q axis. It is shown that the ma- chine can give more torque than its conventional in- terior magnet counterpart if the magnetic saturation of the machine is the same in both cases. The work is supported by results taken from an 11 kw prototype machine.
