Abstract: The current study focuses on the permanent magnet calculations, particularly the cylindrical short-length (small height) permanent magnet. The used model of this permanent magnet takes into account the leakage flux. A procedure for permanent magnet calculations has been developed. Simple equations have been carried out in this study for permanent magnet calculations. These equations show that for short-length permanent magnet, unlike long cylindrical permanent magnet, the value of permeance of the useful (required) magnetic flux path and the permeance of the leakage flux path do not depend on the length of the permanent magnet, but they depend only on the magnet diameter. And for permanent magnet design these equations will be useful.
