Abstract :
A dynamic characteristic analysis algorithm for irreversible demagnetization is developed in this study. Using the developed algorithm, the static and dynamic characteristics of irreversible demagnetization are compared. A maximum current limit for the impact of the irreversible demagnetization in the design of permanent magnet brushless direct current motors is proposed.
