Title: HIGH-STABILITY ROTOR CORE Abstract A high-stability rotor core, characterized in that the rotor core comprises a number of stacked rotor punching sheets and a spindle; shaft holes for fitting to the spindle are provided in centers of the rotor punching sheets, and a number of notches are provided on inner circles of the rotor punching sheets; the notches are communicated with the shaft holes, and the notches are arranged annularly at intervals by taking the center of the shaft holes as a midpoint; a number of peach-shaped holes arranged at uniform intervals are formed on the rotor punching sheets; tips of the peach-shaped holes face the outer side of the rotator punching sheets, and the peach-shaped holes are arranged symmetrically by taking a radius line of the rotor punching sheets as an axis of symmetry; and, each of the peach-shaped holes consists of a triangular hole and a sector hole, the triangular hole being located on an outer side of the sector hole and communicated with the sector hole; there are two notches. |
