Abstract :
Discusses the design of novel permanent magnet structures providing the triangular profile of the magnetic induction, in an airgap. Geometric optimization of these yoked and yokeless structures is carried out by 2-D finite element analysis, for displacement sensor application. Experimental results are in good agreement with analytic calculations. A comparison with previous structures providing a trapezoidal profile of the magnetic induction is presented
