The Use of Quadrature Axis Flux Barriers in Linear Synchronous Machines
The paper explores the use of quadrature axis flux barriers in planar linear synchronous motors.It is shown that the use of the barriers produces a decrease in the flux driven by the armature windings.This leads to a reduction in the tendency for de-magnetisation of the magnets and improved power factor with only a minor reduction in the force.A simple analysis is developed to enable broad assessments of the flux barrier effects and this is validated by the use of 2D finite element analysis in a time stepping routine.The simple analysis is used to consider machines of three different pole pitches with a range of quadrature axis gap dimensions.The braking force produced in short circuit conditions is important in some applications and it is shown that the use of flux barriers gives enhanced forces.
