ELECTRIC ACTUATOR

摘要

Electric motor comprising a rotor (10) comprising a magnetized part (18) defining a plurality of rotor poles, a motor stator (12) comprising a plurality of windings (28) and a magnetic armature (26) defining a magnetic circuit, and a rotor brake device (14). The rotor brake device comprises a mobile element (30) and a brake stator (12b) comprising a magnetic brake armature (26b) and a brake activation winding (46) supported by the magnetic brake armature. The brake activation winding is configured to cause the mobile element to move from a disengaged position in which the rotor is free to turn into an engaged position in which the rotor is held in a static position prevented from rotating. The magnetic brake armature (26b) of the brake stator is secured to the magnetic armature (26) of the motor stator (12).
