Direct-current permanent magnet control mechanism

The invention discloses a direct current permanent magnet control mechanism. The mechanism comprises an upper iron core, a lower iron core and a coil; an elastic device is arranged between the upper iron core and the lower iron core; the coil is electrified to enable the upper iron core to move up and down along the axial direction relative to the lower iron core; and the upper iron core is connected with a driving shaft. According to the direct-current permanent magnet control mechanism of the invention, the transmission efficiency can be greatly improved, and the phase control precision is improved. The direct-current permanent magnet control mechanism has the advantages of simple structure, sensitive driving, high precision, low later maintenance cost, high stability and easiness in later maintenance. 本发明公开了一种直流永磁操纵机构，包括上铁芯、下铁芯与线圈，所述上铁芯与下铁芯之间设有弹性装置，通过对线圈通电，使得上铁芯相对下铁芯沿轴向上下移动；所述上铁芯连接有驱动轴。本发明能够大大提高传动效率，并提高相控控制的精度；采用直流永磁操纵机构，结构简单，驱动灵敏、精度高，后期维护成本低；整体结构较为简单，稳定性高，后期维护简单。
