Fin actuator
This miniature fin actuator manufactured by MPS Microsystems was designed based on customer specifications. Designed to guide a very small object and disposing of an extremely limited space, it meets strict requirements in terms of performance, weight - less than 100 g - and dimensions. To reduce the length of this actuator, MPS Microsystems used part of the screw length as the motor axis. This screw is equipped with a very compact 4-point contact bearing that simultaneously absorbs axial and radial loads. The angular play on the aileron axis is less than 0.1° rms.
This actuator meets the storage and vibration requirements of military equipment.
