Electromechanical actuators (EMAs) convert electrical power directly into mechanical motion through the integration of electric motors — typically brushless DC (BLDC) or permanent-magnet synchronous motors (PMSMs) — with ballscrew, roller-screw, or gearbox drive trains, and encompass associated position-sensing technologies such as resolvers and LVDTs, power electronics, and fault-tolerant winding architectures used across flight-control, landing-gear, and thrust-reverser applications.
How many distinct aircraft programmes each supplier in this area is linked to in our database — a proxy for how widely established a company is across the industry. Bars are relative to the top-ranked supplier.
Whether supply here is concentrated in a few big players or spread across many. Top-5 share is the portion of all programme links held by the five largest suppliers. HHI (Herfindahl–Hirschman Index) runs 0–10,000: under ~1,500 is competitive, over ~2,500 is concentrated.
