Abstract

The utility model provides a motor rotor which comprises a magnet sealing piece, a rotating shaft and a hub, wherein the magnet sealing piece is provided with a first surface and a second surface opposite to each other, and an assembly hole penetrating through the first surface and the second surface; a fixedly connecting part is arranged at the periphery of the assembly hole and axially extends from the second surface to the first surface; a joint end is arranged on the rotating shaft, the joint end is combined with the assembly hole of the magnet sealing piece, and the fixedly connecting part of the magnet sealing piece is combined with the peripheral surface of the rotating shaft near the joint end; the hub is integrally combined with the magnet sealing piece and the rotating shaft; therefore, the bonded area of the magnet sealing piece and the rotating shaft can be increased effectively through the fixedly connecting part.

Description

technical field [0001] The invention relates to a motor rotor and its magnetic sealing part, in particular to a motor rotor capable of increasing the combination stability of the magnetic sealing part and the rotating shaft. Background technique [0002] Please refer to figure 1 As shown, it is the Taiwan Utility Model No. I279063 "Fan and its Rotor" patent case, which discloses a more common existing motor rotor 8, which includes a joint 81, an impeller 82 and a Shaft 83. The joint 81 has a flange portion 811; the impeller 82 is integrally formed on the outer periphery of the joint 81 by injection molding, and the impeller 82 is fitted with the flange 811 of the joint 81; the rotating shaft 83 One end is connected to the joint part 81 , and is riveted to a motor housing 84 by means of the joint part 81 . Accordingly, the motor rotor 8 can be applied to a motor structure, and when the stator of the motor structure drives the rotating shaft 83 to rotate, the impeller 82 ca...
