Abstract

Confirming about the working point of the permanent magnet is an essential premise in the calculating of the permanent magnetic circuit. In this study, the choosing methods about the working point of the permanent magnet are analyzed overall. The calculating formulas of the optimal calculating are deduced using the conception of magnetic energy density. The conclusions can give some guidance to the permanent magnetic circuit calculating and design.

Keywords:
