Description
Technical field
What the present invention relates to is permanent magnet generator, is specially the efficient coreless disc type permanent magnet generator of a kind of breeze start-up.
Background technology
Mostly what wind power generation in the market adopted is permanent magnet generator, and it is made up of rotor magnetic pole and the large parts of stator winding two.Iron core is included in its armature winding, and teeth groove is had on iron core, because it adopts tooth slot structure, namely tooth is used for guiding the magnetic line of force, reduce magnetic resistance, groove is used for inlaying winding, and with the magnetic line of force interlinkage in tooth, tooth and the different magnetic conductivity of groove make rotor diverse location have quantity not wait the magnetic line of force, in the position of the accurate stator tooth of pole pair, ferromagnetic attracting, so that hinder the rotation of rotor of permanent-magnetic power generator, this is just called " slot effect " of permanent magnet generator.Due to the impact of Conventional permanent magnet generator " slot effect ", between the stator of its generator, rotor, reluctance torque can be produced.This starting resistive torque that generator will be overcome not only comprises friction resistive torque, also comprises reluctance torque, and reluctance torque is larger than friction resistive torque.Start resistive torque it directly have influence on wind energy conversion system starting and run time performance, so the existence of reluctance torque in Conventional permanent magnet generator, greatly increases the difficulty of wind energy conversion system breeze-starting.Conventional permanent magnet generator is in order to reduce the magnetic resistance in magnetic circuit simultaneously, substantially be all select the silicon steel sheet stack of high magnetic permeability to be pressed into stator, rotor core, and teeth groove is had on iron core, the high-frequency loss of the Generator Vibration that causes and rotor of slotting causes that the starting resistive torque of generator becomes large, volume is large, weight is large, loss is large, and cost is high.
Summary of the invention
For above-mentioned defect, the invention provides a kind of follow-on permanent magnet generator, solve the defect in the market existing for permanent-magnetic wind driven generator.
For achieving the above object, technical scheme of the present invention is:
1. the efficient coreless disc type permanent magnet generator of breeze start-up, it is characterized in that: taking over a business of its generator respectively includes a rotor with chassis, rotor magnetic pole adopt Nd-Fe-Bo permanent magnet material, magnetic pole be fixed on single solid steel material form disk on form rotor.
2. the efficient coreless disc type permanent magnet generator of a kind of breeze start-up according to claim 1, it is characterized in that: it only has a stator, stator adopts slotless, non iron-core structure, circumferentially arranged by the conductor coils of single triangle, totally three layers, coil is embedded in skeleton and forms armature disc formation stator.

Fig. 1 is structure chart of the present invention: symbol 1 is for taking over a business; Symbol 2 is armature disc; Symbol 3 is round steel dish; Symbol 4 is magnetic pole; Symbol 5 is casing; Symbol 6 is chassis; Symbol 7 is main shaft.Fig. 2 is coil and fixing skeleton drawing thereof: symbol 1 fixes skeleton for coil; Symbol 2 is coil.
Embodiment
In order to deepen the understanding of the present invention, be described further the present invention below in conjunction with drawings and Examples, this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Shown in figure 1: the present invention relates to the efficient coreless disc type permanent magnet generator of a kind of breeze start-up, it is external rotor mechanism, includes two rotors, a stator.Rotor is made up of jointly the round plate of symbol 3 and the magnetic pole of symbol 4, and stator is symbol 2.Electric generator casing is aluminum hull, and rotor magnetic pole has selected the Nd-Fe-Bo permanent magnet material with high-coercive force and high residual flux density.Magnetic pole is fixed on the disk of single solid steel material formation, effectively decreases the eddy current loss of motion generation mutually between permanent magnet and shell.Stator adopts slotless, non iron-core structure.The conductor coils of single triangle circumferentially arranges, and coil is embedded in skeleton and forms armature disc formation stator.In order to fixed armature winding and provide better radiating condition, there is curing time long, the defect that cost is high in the former large multiplex epoxide-resin glue perfusion of armature winding.The present invention adopts the skeleton of insulating material to fix coil.The skeleton of fixed coil adopts phenolic resins or epoxy resin insulation material to be raw material, and printed by 3D printer and form, shaping single coil is directly embedded on skeleton, carries out vacuum paint dipping afterwards, makes coil and skeleton become holistic armature disc.The coil rack that 3D printer prints, not only precision is high, and efficiency is high, highly shortened the curing time needed for epoxy resin perfusion, has saved cost.
Electric generator structure is as Fig. 1, during generator operation, armature disc and main shaft maintain static, the lower hub of wind energy conversion system takes over a business to be connected with generator by connecting dish, just drive wheel hub to rotate when pneumatic equipment blades made rotates, thus by wind energy conversion system turning effort in the external force of upper ball cover, drive upper lower burrs and casing to rotate, the three-phase coil in the magnetic field intercepts armature disc that permanent magnet is produced, creates three-phase alternating current.
The efficient coreless disc type permanent magnet generator of a kind of breeze start-up of the present invention, due to this generator unit stator non iron-core, the magnetic line of force quantity of rotor under any position of generator does not all change, magnetic force equal and opposite in direction under any position, completely eliminate " slot effect ", so generator does not have reluctance torque when starting, only frictional resistance moment need be overcome, this just greatly reduces the starting resistive torque of wind-driven generator, also the starting wind velocity of wind energy conversion system is just greatly reduced, so the energy efficiency of wind power generation also will improve a lot in gentle breeze, start in gentle breeze with regard to easy, so breeze wind is remarkably productive.Owing to adopting permanent magnet excitation, not consuming exciting power, stator non iron-core, there is not saturation problem in magnetic circuit, and generator weight minimizing, non iron-core loss, efficiency are increased, and generator can obtain higher efficiency, and cost is low.According to theory calculate, compared with the cored conventional coreless disc type permanent magnet generator of the same type, its cost reduction 40%, generating efficiency improves about 30%, remarkable in economical benefits, for the market penetration and promotion of wind-driven generator product provides strong technical support.
