An electrical motor can be selectively configured to operator between a number of different configurations to alter the cooling arrangement. The electric motor can include an enclosure aperture disposed through the motor enclosure that can be selectively sealed or opened by a removable cover plate. When the cover plate is installed, the electric motor can operate with a TEFC configuration in which an internal cooling circuit is isolated from an external fluid source. When the cover plate is removed, the internal airflow can thermally interact with an external airflow from an external fluid source.

Provided is a method for removing moisture from a cooling air filter installed for filtering first cooling air for cooling a generator from a first end, the method including: pressurizing second cooling air cooling the generator from a second end; allowing the second cooling air having received heat from the generator to pass through the cooling air filter, in order to absorb and thereby reduce moisture from the cooling air filter.
