Abstract

Closed-form expressions are presented for computing the force and torque that is transmitted by synchronous axial couplings. These expressions enable rapid parametric studies of coupling performance relative to the selection of magnet material, dimensions, and spacings. They are also useful for testing three-dimensional numerically based field algorithms. The derived expressions are tested here using data taken from a ceramic coupling.
