A drivetrain includes an electric machine, an inverter, and a controller. The controller, for a given operating point of the electric machine, may schedule a method of commutation for switches of the inverter during presence of a negative wheel torque request according to a charge rate corresponding to the negative wheel torque request, temperatures of the electric machine and/or inverter, and/or a battery state of charge.

A multi-disk brake system comprises an electrical generator disposed therein. The electrical generator is configured to convert mechanical energy to electrical energy. The mechanical energy may be generated during a braking event of the multi-disk brake system. The electric generator may power various electrical components on the aircraft or store the electrical energy in a capacitor bank. The electric generator may also act as a motor and/or power a landing gear in a motor configuration.
