1. A method of removing heat from an electrical machine located in a gas turbine engine at least partially inward of a core airflow path in a radial direction, the electrical machine comprising an outer electrical machine stator and an inner electrical machine rotor, the method comprising:
directing a liquid coolant radially inward past the outer electrical machine stator and toward an inner electrical machine rotor using a coolant passageway; and
directing the liquid coolant radially outward along a rotor support that connects the electrical machine to a rotary member and toward the inner electrical machine rotor thereby removing heat from the inner electrical machine rotor.
