High Temperature Alternator for Geothermal Applications

Among other things, the present disclosure relates to an alternator for high temperature applications, (i.e., an alternator capable of operating at temperatures greater than approximately 250 degrees C.). The alternator for high temperature applications may include permanent magnets arranged in a topology which may enable the alternator and connected application system to start operating without an external or auxiliary power source. When used in geothermal applications, the alternator may be capable of using drilling fluid as a coolant.
