Systems and methods for electric damping of aircraft flight control surfaces and propellers

A motor control system for an aircraft, including:

• a controller;
• a first resistor;
• and
• at least one first switching device configured to control current flow to coils of a motor, wherein:
• the controller is configured to control a second switching device to prevent current flow through a third switching device and the first resistor when a power source of the aircraft is providing power,
• the third switching device is connected in series with the first resistor and is configured to allow current generated by a back EMF (electromotive force) voltage to turn on the third switching device and to flow through the first resistor when the power source of the aircraft is not providing power, the back EMF voltage being created by movement of a moveable aircraft structure of the aircraft, and
• the at least one first switching device is configured to allow current flow across it and through the first resistor when the power source of the aircraft is not providing power.
