Abstract
A generator incorporating a double sided fan operable to generate dual, spaced apart, simultaneous cooling airflows within the generator to more efficiently cool internal components located on opposite sides of the fan. The double sided fan generates a first cooling airflow into a permanent magnet generator (PMG) assembly and a second cooling airflow through an electronics assembly. The first cooling airflow cools a stator disposed within the PMG assembly, while the second cooling airflow cools a plurality of circuit boards disposed within the electronics assembly. The fan exhausts both cooling airflows radially outwardly.
