| Zusammenfassung: | An electromechanical actuator comprises a brushless DC electric motor (12) with an electronic switch, the motor (12) comprising a rotor (13) and a stator (14) positioned coaxially about an axis of rotation (X). The rotor (13) comprises a rotor body (15) provided with magnetic elements (16) surrounded by the stator (14). The magnetic elements (16) surround the rotor body (15) and constitute a permanent magnet and pole pairs. The stator (14) is formed by a stator core (17) having pole elements (28) distributed over the periphery of the stator (14). The pole pieces (28) have a width of angular polar opening (A) at least two times smaller than the angular width (alpha 1) of the magnetic elements (16) of a first rotor (13). |
