Abstract

PURPOSE: To try not to demagnetize a permanent magnet by operating a rotary machine using the permanent magnet as a field in a controller having the functions of a lien ka(in Japanese kana characters) regenerative braking, even if an excessive current is applied to an armature circuit due to a commutation failure at the time of line ka and regenerative braking.
