Abstract
Disclosed is a permanent magnet submersible motor rotor structure with a starting mouse cage. Steel magnets are respectively embedded into various embedding grooves of a tubular magnetic yoke, each rotor iron core and copper end rings at two ends of the rotor iron core are respectively provided with inner-circle axial embedding grooves corresponding to tops of the various steel magnets, the rotor iron cores and the copper-end rings are also provided with inter-pole magnetic shielding mechanisms consisting of opening holes and opening grooves, the rotor iron cores are correspondingly arranged among the various steel magnets at intervals, the opening holes and the opening grooves are communicated with each other, and the rotor iron cores and the copper-end rings which are located among the opening holes are provided with conducting bar holes. The tubular magnetic yoke is fixed to the surface of a rotor shaft by a key, the rotor shaft essentially becomes a composite shaft, and accordingly the torsional strength of the rotor shaft is strengthened. The torsional strength of the rotor shaft is particularly important for a slim rotor in a permanent magnet submersible motor, can guarantee axial straightness of various magnetic poles and effectively prevents decrease of power outputted by the motor due to staggering of polarities of a magnetic field. The rotor structure and conducting bars form the mouse cage, so that the permanent magnet motor has a self-starting function. In addition, the permanent magnet submersible motor rotor structure has the outstanding advantages that the permanent magnet submersible motor rotor structure is reasonable in structure and particularly applicable to permanent magnet submersible motors with 12 poles, 16 poles, 22 poles or 24 poles.
Description
Technical field
The utility model belongs to the permanent magnetism submersible electric machine with oil, particularly relates to a kind of permanent magnetism submersible electric machine with oil rotor structure of tape starting mouse cage.
Background technology
The disclosed rotor structure of the application for a patent for invention of application number 200910071064.X " a kind of rotor structure that is used for 12 utmost point permanent magnetism submersible electric machine with oils " is following: armature spindle is axially arranged with each rotor unit; Said rotor unit is provided with the magnetic pole of tubular yoke, magnet steel and the superimposed formation of punching; Tubular yoke is fixed in the armature spindle surface by key; The cross section is that 12 magnet steel of rectangle are symmetrically distributed in tubular yoke surfaces; Each magnet steel upper surface is respectively equipped with magnetic pole; Each magnetic pole is provided with opening sliver groove, and the both sides end face of said each magnet steel and magnetic pole is provided with and the separated magnetic end ring of the copper of its fluid-tight engagement, and each copper bead in the magnetic end ring engages with the boss at tubular yoke two ends respectively; Said each copper is at a distance from magnetic end ring periphery corresponding 24 open pores in position that have been spacedly distributed; 12 wherein alternate open pores are corresponding with the opening sliver groove of each magnetic pole respectively, and said both sides copper is respectively equipped with the sliver that two ends are end cap at a distance from magnetic end ring position corresponding 24 open pores, 12 wherein alternate slivers respectively with the corresponding joint of opening sliver groove of each magnetic pole.
Though above-mentioned rotor structure makes the permanent magnetism submersible electric machine with oil have self-starting function, there is the defective that requirement on machining accuracy is high, inconvenience is assembled in the cage-shaped structure that is made up of at a distance from the sliver in the magnetic end ring open pore at a distance from the alternate setting of magnetic end ring, magnetic pole and copper magnetic pole and copper.
Summary of the invention
The utility model is the permanent magnetism submersible electric machine with oil rotor structure that discloses a kind of tape starting mouse cage for the technical problem that requirement on machining accuracy is high, inconvenience is assembled that solves foregoing invention patent application existence.
The utility model is taked following technical scheme for realizing above-mentioned purpose: this rotor structure comprises armature spindle, tubular yoke, magnet steel and sliver; Characteristic is; Said cross section is that each magnet steel of rectangle embeds equally distributed each the axial caulking groove of tubular yoke surfaces respectively; The interior circular shaft that the rotor core that superimposed punching constitutes and the copper end ring at rotor core two ends are provided with respectively corresponding each magnet steel top is to caulking groove; Pairing rotor core in interval and copper end ring are provided with the separated magnetic mechanism of the interpolar that is made up of the open pore that is connected and the groove of remaining silent between each magnet steel, and rotor core between the open pore and copper end ring are provided with the sliver hole, and each sliver hole is provided with the sliver that two ends are end cap.
The utility model can also be taked following technical measures:
Said sliver is the copper sliver.
The beneficial effect and the advantage of the utility model are: the armature spindle surface key of this rotor structure is fixed with tubular yoke, makes armature spindle become composite shaft in fact, thereby has strengthened the torsional strength of armature spindle.The armature spindle torsional strength is particularly important in the elongate rotor of permanent magnetism submersible electric machine with oil, and it can guarantee each magnetic pole linearity in the axial direction, effectively avoids because of polarity of the magnetic field the reduction of exerting oneself of the staggered motor that causes taking place.The magnet steel of this rotor structure is supported by the tubular yoke of bottom surface, and the integral rotor iron core that is made up of superimposed punching above presses, and therefore fixes reliably and make the simple of packaging technology change.This rotor structure form mouse cage with sliver, make magneto have self-starting function.The utlity model has outstanding advantage rational in infrastructure, as to be specially adapted to 12,16,22,24 utmost point permanent magnetism submersible electric machine with oils.
