Description
Technical field
The utility model relates to a kind of permanent magnet generator, particularly a kind of lightweight permanent-magnetic wind driven generator.
Background technology
General permanent-magnetic wind driven generator is solid construction, and no matter the magneto of solid construction (is inner permanent magnetic type IPM; Surface permanent-magnet type SPM; Still inlay permanent-magnet type ISPM) weight is all bigger, and specific power is less relatively.Definition according to specific power (W/kg); Improve specific power, must alleviate important.The rotor of permanent-magnetic power generator that has occurred hollow-core construction in recent years, as Chinese patent 96227429.1, a kind of permanent-magnetic wind driven generator rotor is disclosed, it is multiedge cylinder with holes in the middle of in the outside of rotating shaft, be bonded with the strip permanent-magnet steel at the multiedge cylinder outer cylinder, the rotor of permanent-magnetic power generator of this hollow-core construction, though weight alleviates significantly, but air gap flux density is inhomogeneous, occur easily in the running " sweeping thorax ", power output is lower, increases by one bonding process on the technology, and reliability is low when running up.
The utility model content
The utility model aim to provide a kind of in light weight, moment of inertia is little, easily realize breeze start-up, generating, with the air gap of thorax in the stator evenly and the lightweight permanent-magnetic wind driven generator of the high hollow-core construction of specific power.
The lightweight permanent-magnetic wind driven generator comprises: permanent-magnet steel, rotor core, stator core, coil, casing, bearing, rotating shaft, stator core, rotor core laminate into cylindric by the different annular punching silicon-steel of diameter, the upper and lower end face is compressed by top board and lower platen, and is fixing with the welding of rotating shaft cooperation place in the middle of top board and the lower platen.
The permanent-magnet steel that the uniform alternating polarity of rotor core periphery is alternate, being installed together of this permanent-magnet steel and rotor core correspondence form complete columnar structured.
Rotor core adopts top board and the lower platen of band boss, the corresponding installation with the internal diameter of rotor core of the external diameter of boss.
Stator winding adopts double-deck chain type winding, all coils shape of double-deck chain type winding and measure-alike, and three-phase coil embeds in 36 grooves of stator core.
Stator winding of the present utility model adopts double-deck chain type winding, for improving electromotive force and magnetomotive force waveform (near sinusoidal waveform), has selected suitable short distance winding for use, not only improves the electric property of generator, and can save electromagnetic wire and the leakage reactance that reduces winding.In addition, all coils shape and the size of two layer winding are all identical, are convenient to coiling, and end arranged cells is neat, are conducive to heat radiation and increase mechanical strength.Coil distributes compact, and effective rate of utilization height, three-phase coil rationally embed in 36 grooves of stator core.The unit of contrast identical weight, exportable more powerful, in light weight under equal-wattage, size is little, saves effective material (copper cash, silicon steel sheet), has reduced the cost of unit.Be specially adapted to be contained in the wind-driven generator on the electric pole.
