ABSTRACT:
An improved electromagnet assembly is disclosed for use in electrically actuated drum brakes. The electromagnet assembly has a cup shaped stamped metal housing. A center pole is mounted in a central opening in the housing which has stepped edges so as to alternately engage the center pole and form arcuate gaps about the center pole. A flux washer is positioned on the center pole to bridge the gaps for increasing the efficiency of the electromagnet. A solenoid winding is positioned within the opening defined by the housing, the flux washer and the center pole and the opening is closed with a friction material.
