Abstract :
The field distribution when a thin conducting sheet moves with constant velocity between two rectangular and infinitely permeable pole pieces of an electromagnet is obtained by conformal mapping, after reduction of the problem to two dimensions. This result is used in predicting the force/speed and flux/speed characteristics of eddy-current brakes with nonmagnetic rotors. Experimental results on several brake configurations justify the validity of the analysis.
