Problems solved by technology

After one winding of the fault-tolerant motor fails, the remaining windings can continue to work. This type of electromechanical actuator can effectively reduce the moment of inertia on the input side of the actuator without a reducer, and has better adaptability to power levels and load sizes. However, the technology is still immature and has not yet been applied in practice.

Abstract

The application discloses a dual-redundancy electromechanical actuator comprising: an actuating lever configured to linearly reciprocate in a first direction; a first motor configured to drive the actuating rod to linearly reciprocate through a first transmission system; and a second motor configured to drive the actuating rod to linearly reciprocate through a second transmission system. The firsttransmission system includes a first clutch configured to open the first transmission system or to close the first transmission system. The second transmission system includes a second clutch configured to open the second transmission system or to close the second transmission system. The dual-redundancy electromechanical actuator further includes a controller configured to control the first clutch and the second clutch to achieve the dual-redundancy operation of the actuating rod.

Description

technical field [0001] This application relates to the field of aerospace technology, in particular, to a dual-redundancy electromechanical actuator. Background technique [0002] In the aerospace electromechanical servo system, the use of redundant electromechanical actuators is an effective way to improve reliability. [0003] In the past, redundant electromechanical actuators mostly used differential gears or fault-tolerant motors. The differential can effectively avoid force disputes when working at the same time, but it will increase the moment of inertia, moment of inertia and weight, so it is mostly used in occasions with low power and small load. After one winding of the fault-tolerant motor fails, the remaining windings can continue to work. This type of electromechanical actuator can effectively reduce the moment of inertia on the input side of the actuator without a reducer, and has better adaptability to power levels and load sizes. But the technology is still ...
