Abstract: A fluid-cooled electromagnet includes an upper housing, a lower housing vertically aligned with the upper housing, a plurality of pancake coils disposed between the upper housing and the lower housing to be spaced apart from each other and sequentially stacked to have a washer shape, and at least one spacer, disposed between the upper housing and the lower housing, accommodating the pancake coils at regular intervals.

Abstract: An electromagnet includes insulating cooling plates of a ceramic material which are vertically arranged parallel to each other, washer-shaped insulating center spacers maintained at a constant distance between adjacent insulating cooling plates, pancake coils including Litz wires which are spirally wound on each of the insulating center spacers in the space between the adjacent insulating cooling plates, and a housing which covers at least outer side surfaces of the insulating cooling plates and the pancake coils and provides a coolant to cool the insulating cooling plates.
