Servo motor magnetic steel deflection apparatus

The utility model relates to a servo motor magnetic steel deflection apparatus, comprising a rotating shaft (1) and magnetic steels (3). Each magnetic steel (3) is in a shape of a tile; a plurality of pieces of magnetic steels are provided and are connected end to end in a row to be pasted on the excircle surface of the intermediate part of the rotating shaft (1); the outside circular surface of the intermediate part of the rotating shaft (1) is sleeved by a magnetic steel deflection sleeve (2); the positions of the magnetic steel deflection sleeve (2) corresponding with the magnetic steels (3) are provided with notches (6); one side of the notch (6) is a straight line edge, and the other side is a continuous step edge (4) successively connected by a plurality of steps; the magnetic steels (3) are pasted tightly with corresponding steps one by one. The servo motor magnetic steel deflection apparatus has a simple structure, and substantially raises magnetic steel deflection installation efficiency and angle ac
