A direct current dynamoelectric machine characterized by having a plurality of salient field poles each comprising a rigid laminated base member, a relatively more flexible laminated face member, and a plurality of permanent magnet sub-assemblies mounted between and adhered, respectively, to the base member and face member. The magnet sub-assemblies each comprise a plurality of rare earth permanent magnet bars arranged in a predetermined configuration and compressed between a pair of flat magnetically permeable metal plates to which the bars are adhered with a partially cured adhesive.
