Abstract
The invention relates to a rotor structure of a permanent-magnet submersible motor with a starting squirrel cage, wherein magnetic steels are nested into corresponding caulking grooves of a tubular magnetic yoke; the rotor core and copper end rings at both ends are provided with inner cycle axial caulking grooves corresponding to the top parts of the magnetic steels; the rotor core and the copper end rings which are correspondingly arranged among the magnetic steels at intervals are provided with a pole separation magnetic mechanism consisting of open holes and closed slots; conducting bar holes are arranged on the rotor core and the copper end rings among the open holes; and the tubular magnetic yoke is fixed on the surface of a rotor shaft in the structure so that the rotor shaft substantially becomes a combined shaft, thereby enhancing the tensional strength of the rotor shaft. The tensional strength of the rotor shaft is important for the thin and long rotor of the permanent-magnet submersible motor so as to ensure the straightness of the magnetic poles in the axial direction and effectively avoid the reduction of the motor output which is caused by polar intersection of the magnetic field. The structure of the rotor forms a squirrel cage with the conducting bars, so that the permanent-magnet motor has a self-starting function. The invention has the outstanding advantage of reasonable structure and is particularly applicable to 12, 16, 22 and 24-pole permanent-magnet submersible motors.
Description
Technical field
The invention belongs to the permanent magnetism submersible electric machine with oil, particularly relate 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 present invention 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 present invention takes 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 present invention can also take following technical measures:
Said sliver is the copper sliver.
Beneficial effect of the present invention and advantage 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 outstanding advantage that the present invention has is rational in infrastructure, be specially adapted to 12,16,22,24 utmost point permanent magnetism submersible electric machine with oils.
