Controlling blade pitch by a plurality of electric motors

The present invention relates to a rotor assembly where a number of electric motors provide one or more of the task of: rotating the rotor, controlling collective pitch or controlling cyclic pitch, by varying the relative rotational angle between two or more associated electric motors. The present i...

Beschreibung
Zusammenfassung:	The present invention relates to a rotor assembly where a number of electric motors provide one or more of the task of: rotating the rotor, controlling collective pitch or controlling cyclic pitch, by varying the relative rotational angle between two or more associated electric motors. The present invention relates to a rotor assembly where associated electric motors are configured to rotate the rotor, control the collective pitch of the rotor/assembly, and/or control the cyclic pitch of the rotor/assembly, by varying the relative rotational angle between two or more of the associated electric motors.
