Abstract :
DURING RECENT YEARS the progress made in the development of permanent-magnet materials has brought about a considerable increase in the use of permanent-magnet rotors in d-c instruments. One such application is in the d-c Selsyn position indicator,1 another in a newly developed electric instrument,2 and a third in a new ratio-type instrument.3 The space limitations in these designs predicated small actuating elements which were obtained by using permanent-magnet moving systems.
