Problems solved by technology

The existing long iron core rotor structure cannot guarantee that the rotating rotor and stator will not collide when the rotating shaft is deflected, and the operation reliability of the long iron core oil-filled submersible permanent magnet synchronous motor cannot be guaranteed.
The existing long iron core rotor often has technical problems such as rotor sweeping during work, which has potential safety hazards and even causes production accidents

Embodiment 1

[0026] Refer to attached Figure 1 to Figure 5 .

[0027] A rotating magnetic steel oil-filled submerged permanent magnet synchronous motor rotor, characterized in that: the motor rotor is composed of several yokes 3 fixed with magnetic steel 2, and each yoke 3 is connected and fixed on a rotating shaft through a key 7 1, the magnetic steel 2 is fixed on the surface of the yoke 3. There is a rotating shaft centralizing mechanism between every two sections of yokes 3 . The rotating shaft righting mechanism is made up of bearing body 4 and bearing sleeve 5, and bearing body 4 and bearing sleeve 5 are relatively assembled together. The bearing sleeve 5 is fixed on the rotating shaft 1 through the key 8; the bearing body 4 is located outside the bearing sleeve 5, and the bearing body 4 cooperates with the stator core 9; the rotating shaft 1 drives the bearing sleeve 5 to rotate and forms a sliding bearing pair with the bearing body 4 . The outer ring of the bearing body 4 has ...

Abstract

The invention relates to a rotary magnetic steel oil-filled type subducted permanent magnet synchronous motor rotor, which belongs to the technical field of motors. The rotary magnetic steel oil-filled type subducted permanent magnet synchronous motor rotor is characterized by comprising a plurality of sections of magnet yokes fixedly provided with magnetic steels, and a rotating shaft centering mechanism is arranged among the magnet yokes. The rotary magnetic steel oil-filled type subducted permanent magnet synchronous motor rotor has the advantages of simple structure, convenient assembly, reliable performance, good using effect, and the like, can meet the power demand of high-capacity oil extraction equipment, expand the application range of a three-phase permanent magnet synchronous motor in the field of oil extraction power, greatly enhance the operating reliability of a permanent magnet motor, and guarantee the motor to operate normally for a long time.

Description

technical field [0001] The invention belongs to the technical field of electric motors, in particular to a rotor of a rotating magnetic steel oil-filled submerged permanent magnet synchronous motor. Background technique [0002] At present, the rotor structure of the rotating magnet steel type permanent magnet synchronous motor used is a short iron core rotor structure, that is, the yoke is installed on the rotating shaft, and the magnetic steel is fixed on the yoke; the other is a long iron core rotor structure, namely Fix the magnetic steel directly on the shaft. Due to the limitation of the well diameter, the outer diameter of the rotating magnet steel oil-filled submersible permanent magnet synchronous motor, its rotor diameter, and the diameter of the shaft are small, so the length of the iron core is long, and the phenomenon of deflection of the shaft is common. The existing long iron core rotor structure cannot guarantee that the rotating rotor and stator will not co...
