The invention relates to an actuator including an electrical machine. The electrical actuator () comprising: a polyphase machine (); at least one connection member () for powering the actuator from at least one network () delivering alternating current; and first and second buses () connected in parallel between each connection member () and the machine () for applying frequency control thereto. Each inverter () comprises a plurality of arms each having two controlled switches, each phase of the machine () being connected both to the two switches of an arm of the first inverter () and also to the two switches of an arm of the second inverter (). The actuator further comprises controlled connection and disconnection means interposed between each bus () and each connection member. The invention is applicable to actuators used in aviation.
