The method for manufacturing the rotor.
Background technique
For the permanent magnet direct-drive generator of Large-scale Wind Turbines, two significant design indexs are to reduce generator
Cogging torque and torque pulsation.The cogging torque of generator is smaller, it is meant that and wind power generating set has lower incision wind speed,
The revolving speed range of operation for expanding unit, improves wind energy utilization and unit generation amount.The torque pulsation of generator is smaller, wind
The operation stability of power generator group is higher, and the service life of the rotary parts such as bearing is longer.
In order to reduce cogging torque and the torque pulsation of generator, common solution is electricity in design of electrical motor at present
Machine uses skewed stator slot mode or skewed-rotor mode.According to motor stator skewed slot mode, can not only it make coil because of skewed slot
The problems such as angle and be difficult to manufacture, coil length can also increased, winding resistance increase, cause the copper loss of motor to increase, hair
Heat increases.Pole mode oblique for rotor, referring to Fig.1, according to each magnetic pole in rotor rim is axially inclined
Mode needs each magnetic pole 1 in rotor rim 2 is axially inclined along motor, it is meant that magnetic pole 1 or rotor rim 2 must be made into
Abnormity (that is, other shapes other than the conventional pole form such as cuboid), this not only increases magnetic pole 1 or rotor magnetic
The manufacture difficulty of yoke 2 also increases the processing and manufacturing difficulty of required mold and tooling when producing and assembling magnetic pole 1, greatly drops
The low yield rate of magnetic pole 1 or rotor rim 2, causes product cost to increase.In addition, referring to Fig. 2, the oblique pole mode of rotor
The magnetic pole 11 by the upward multistage routine of motor shaft be can be along certain angle (that is, step skewed pole) is axially offset, still, this
Size Control precision when assembling to magnetic pole 11 proposes strict demand, reduces the yield rate and assembly efficiency of magnetic pole 11, into
And reduce production efficiency.
In addition, the projected life of generator is usual particular, it is important that the operating condition of wind power generating set is complicated and changeable
It is required that even 25 years 20 years, this requires the fixation of rotor magnetic pole and process for protecting provide higher resistance to mechanical fatigue can and it is resistance to
Corrosive nature.The fixed form of rotor magnetic pole mainly has surface-mount type and two kinds of plug-in type.Surface-mount type magnetic pole technique for fixing is by magnetic
Pole is fixed on rotor rim surface by resin bonding.Surface-mount type magnetic pole technique for fixing passes through resin bonding power due to magnetic pole completely
It is fixed on rotor rim surface, once occur sealed thin weakness in process, in wind power generating set long-time high temperature
Under degree, high humility service condition, easily there is corrosion dusting since sealing is insufficient in magnetic pole, in turn results in stickup of the resin to magnetic pole
Failure, the magnetic pole finally corroded under the action of mutually exclusive power, are detached from rotor and jump out phenomenon, cause between magnetic pole
Tower accident under stator and rotor abrasion or even generator failure.Plug-in type magnetic pole technique for fixing, magnetic pole is inserted in place in rotor
In the slot of iron core, then by end plate fixed magnetic pole axial ends, realize the fixation to magnetic pole.Although plug-in type magnetic pole technique for fixing
It is realized by slot stationary structure and magnetic pole is reliably fixed, but still there is magnetic poles to seal insufficient hidden danger, in wind
Under power generator group long-time high-temperature, high humility service condition, magnetic pole easily occurs corroding dusting, to weaken rotor magnetic
The magnetic flux of pole and the gap density of generator, thereby reduce the generated energy of wind power generating set.
