ABSTRACT:
A device and system for removing heat from a magnetic device such as an electromagnet core section of a magnetic bearing internally by convection. The device includes a ribbon-type conductor portion and an insulator portion that are spirally and coaxially arranged on a coil. The insulating portion includes window portions that provide a fluid passage when the insulating portion is sandwiched between adjacent conductor portions. The device can be disposed in a plenum in the electromagnet core section and at least one opening in the core section, through which a cooling fluid can be introduced into the plenum, can be provided.
