摘要： An electronic brake system includes an electromagnet housing in which an inner disk install end is integrally formed around the inside surface. An electromagnet is disposed inside of the electromagnet housing. A motor plate is installed at a motor/generator, and in which an outer disk install end disposed outside of the inner disk install end in a radial direction is integrally formed around one side surface. A disk unit is provided in which a plurality of the inner disks and the outer disks are overlapped between the inner disk install end and the outer disk install end to be combined each other through friction by virtual pressure. A piston is disposed according to the inside surface of the electromagnet housing, connected with a plunger being introduced along the support end of the rear cover, and operated by electromagnetic force of the electromagnet to supply virtual pressure to the disk unit.
