Abstract
An electric actuator includes a threaded rod turned by a motor, the threaded rod having a drive zone extended on each side by threaded zones, one of the threaded zones collaborating with a stationary nut and the other of the threaded zones collaborating with a nut secured to a control member capable of translational movement along an axis parallel to the axis of the threaded zone, the threaded rod being moved with a helical motion.
Claims33
An electric actuator, comprising:
- a threaded rod actuated in rotation by a motor;
- said threaded rod having a drive zone, which is driven by a rotor of said motor and which is extended on each side by threaded zones;
- one of said threaded zones cooperating with a fixed nut;
- another one of said threaded zones cooperating with a nut integral with a control member adapted to move along a first axis parallel to a second axis of said threaded zone;
- and
- said threaded rod being moveable in a helical movement;
- wherein said motor includes a stator interacting electromagnetically with said rotor provided with a permanent magnet, mechanically connected to said drive zone;
- and
- wherein said magnet is moulded onto said threaded rod driving said control member.
