Abstract

1503708 Core constructions for dynamoelectric machines KOLLMORGEN CORP 27 Aug 1975 [30 Aug 1974 9 May 1975 16 June 1975] 35321/75 Heading H2A To enable the permanent magnets 46, 47 of an electric motor rotor comprising the magnets and soft magnetic polepieces 45 to be magnetized in situ the pole-pieces 45 have flux carrying cross-sectional areas which are at least 1À5 times larger than is required to carry the flux of the magnets, when magnetized, without saturation.
