Description

technical field [0001] The invention relates to an electromechanical actuator, in particular to a highly integrated electromechanical actuator and an application method thereof. Background technique [0002] Electromechanical actuator, as a commonly used power-by-wire actuator, is a device that is powered by a motor, drives the actuator through a transmission, and finally converts rotational motion into linear reciprocating motion. It is widely used in automobiles, trains and in aviation and other fields. [0003] In the prior art, the electromechanical actuator usually adopts the design method of building blocks, simply piece together the drive motor, transmission mechanism and displacement sensor and other components, which has the defects of complex structure and large volume and weight. In addition, due to the relatively large transmission link It also leads to a decrease in system stiffness and transmission efficiency. Contents of the invention [0004] Aiming at th...
