Abstract
The invention discloses a rotor of a high-power high-speed permanent magnet generator. The problem that a magnetic steel surface attached type motor rotor is restricted by industrial glue for adhering magnetic steel and the self intensity of the magnetic steel is solved. Two ends of a rotor shaft (1) are fixedly provided with a fan set (2) respectively; the inner sides of the fan sets (2) fixedly arranged at the two ends of the rotor shaft respectively are both provided with pressing plates (3); a plurality of iron core sections (6) are arranged between the two pressing plates (3) fixedly arranged at the two ends of the rotor shaft (1) respectively; radial ventilating ducts are arranged between the adjacent iron core sections (6); rotor rinsing plates (7) with ventilating sheets are arranged in the radial ventilating ducts; closed trapezoidal magnetic steel grooves (10) are uniformly arranged in the outer side surface of each iron core section (6) along a circumferential direction; the thicknesses of separating ribs (11) between the adjacent closed trapezoidal magnetic steel grooves (10) are 4 millimeters; and trapezoidal magnetic steel (4) is arranged in the trapezoidal magnetic steel grooves (10). The rotor of the high-power high-speed permanent magnet generator has a simple structure, and is safe and reliable.
Description
Technical field
The present invention relates to a kind of rotor of generator, particularly a kind of rotor of Large-power High-Speed generator.
Background technology
Along with the increase of permanent magnet generator capacity, the improving constantly of working speed, the rotor of traditional magnet steel surface-mount type has received pastes the industrial glue of magnet steel and the restriction of the intensity of magnet steel own.When rotating speed was too high, the glue of pasting magnet steel can't provide enough cohesive forces, guarantees the mounting condition of magnet steel; Even perhaps glue can provide enough cohesive forces, but because the strength problem of magnet steel itself, magnet steel may be chipping when high-speed cruising, has serious potential safety hazard.In addition, the cooling structure of generator is also particularly important.As everyone knows, do not produce heat basically at high rotating speed, big capacity magneto rotor, the main thermal source in the motor is a stator.If the cooling structure design is improper, the heat that causes stator to produce can not in time be derived, and motor can be in the hot operation state for a long time like this, and the magnet steel possibility is loss of excitation because working temperature is higher, thus the electrical fault of causing.
Summary of the invention
The invention provides a kind of rotor of Large-power High-Speed permanent magnet generator, the rotor that has solved the magnet steel surface-mount type has received the problem and the cooling problem of capacity magneto greatly of the restriction of the industrial glue of pasting magnet steel and the intensity of magnet steel own.
The present invention overcomes the above problems through following scheme:
A kind of rotor of Large-power High-Speed permanent magnet generator; Comprise armature spindle; Two ends at armature spindle are set with fans respectively, and the inboard of the fans that fixedly installs respectively at two ends is provided with pressing plate, are provided with a plurality of core packets between two pressing plates that fixedly install respectively at described armature spindle two ends; Between adjacent core packet, be provided with radial ducts; In this radial ducts, be provided with the rotor punching of band cowl flap, in the lateral surface of each core packet, along the circumferential direction evenly be provided with the trapezoidal magnet steel groove of sealing, the thickness of the muscle between the trapezoidal magnet steel groove of adjacent sealing is 4 millimeters; In the trapezoidal magnet steel groove of sealing, be provided with trapezoidal magnet steel, on the left and right sides face of each core packet vertical, be provided with baffle plate with armature spindle.
Be provided with block and packing ring respectively between fans that fixedly installs respectively at the two ends of armature spindle and the pressing plate.Core packet is fixed on the armature spindle through block.
The invention solves the motor potential problem that the magnet steel safety brought installs that runs up, simultaneously, owing on rotor, increased radial ducts, make rotor that the power source of cooling air is provided when work, guaranteed the working temperature of magnet steel.
