Assignee: GOODRICH ACTUATION SYSTEMS SAS
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  F | IPC H

Claim 0:
1. An electromechanical actuator, comprising:
an actuator rod housed in an actuator housing;
a linear variable differential transformer (LVDT) fixed to the actuator housing and having an LVDT body having an outer surface that includes a first anti-rotation surface feature; and
an anti-rotation component configured to contact the outer surface of the LVDT,
wherein said anti-rotation component comprises:
a second anti-rotation surface feature, and
wherein said first and second anti-rotation features are sized and shaped relative to each other such that, when in contact with each other, they prevent rotation of the actuator rod in use;
wherein the electromechanical actuator further comprises:
a motor; and
a mechanical converter configured to transform torque produced by the motor into linear force applied to said actuator rod;
wherein the actuator rod comprises a hollow cylindrical region surrounding the LVDT; and
wherein said anti-rotation component is directly machined onto an inner surface of the actuator rod and is positioned around the outer surface of the LVDT body.
