The utility model discloses a brushless moment actuating mechanism of butterfly finite rotation, including drive shaft and two drive unit, two drive unit symmetric distributions in the both sides of drive shaft, drive unit includes stator and rotor, the stator is curved stator core by the section and the stator winding that inlays on it constitutes, the rotor is curved magnetic conduction yoke by permanent magnet and section and constitutes, said permanent magnet is fixed in the magnetic conduction yoke, and the both ends of two drive unit's stator link to each other by a stator ring flange respectively, and the both ends of two drive unit's rotor link to each other by a rotor ring flange respectively, and two drive unit's rotor links to each other with the drive shaft by two rotor ring flanges. The utility model discloses can arrange actuating mechanism's two unit in arm of force maximum position that it lands to show has increased driving moment coefficient and moment -weight ratio, be particularly useful for requiring on the jumbo size platform of little corner work the occasion of low-speed even running.
