Abstract
The utility model relates to a multipole inner stator structure for a miniature wind power generator, which comprises an annular stator yoke iron core, a solenoid type coil, a stator support, a shaft sleeve, a generator shaft, a bearing and a plurality of stator tooth iron cores, wherein a stator is arranged on the stator support, the stator support is connected with the generator shaft through the shaft sleeve, the bearing is arranged on the generator shaft, dovetail grooves with the same quantity as the stator tooth iron cores are equivalently arranged on the outer circle of the annular stator yoke iron core, a dovetail head is arranged on a small head of each stator tooth iron core, each stator tooth iron core is mutually joggled and fixed with the dovetail grooves on a stator yoke iron core body through the dovetail heads, and the solenoid type coil is sleeved outside the stator tooth iron cores. The multipole inner stator structure has the advantages of simple structure, low production cost and long service life, improves the working efficiency of the generator and can ensures that the generator stably works for a long time.
Description
Technical field
The utility model relates to a kind of stator and manufacture method thereof of wind-driven generator, relates in particular to a kind of micro wind turbine generator with multipole internal stator structure and manufacture method thereof.
Background technology
Wind energy is a green regenerative energy sources, blower fan exploitation, use more and more wider, miniature in the market or small-sized wind power generator is used is the internal rotor permanent-magnetic generator.Mainly there is following shortcoming: 1, number of poles few (generally being the 4-8 utmost point), with the supporting step-up gear that needs of blower fan, production cost, safeguard the use cost height, volume and weight is all very big; Though it is stable that 2, internal stator directly drives generator, because fan blade directly is contained on the shell, moment of inertia is big; Though 3, internal rotor generator moment of inertia is little, easy driving when zero load or strong wind; 4, the traditional wind stator is to become monolithic construction with the silicon plate punching out, and the silicon steel material utilance is low; 5, the conventional motors stator can only rule, and production efficiency is low; 6, the traditional stator insulating treatment process is a dipping lacquer, and the class of insulation is lower, and protective capacities is more weak as dustproof, waterproof, anti-salt fog, mildew-resistant, and useful life is short.
The utility model content
The utility model provides a kind of micro wind turbine generator of saving cost, production efficiency height, long service life with multipole internal stator structure in order to overcome the above problems.
The technical scheme of the utility model product is: comprise annular stator yoke core, the solenoid type coil, stator support, axle sleeve, generator shaft, bearing and a plurality of stator tooth iron core, described stator is arranged on the stator support, stator support is connected with generator shaft by axle sleeve, generator shaft is provided with bearing, described annular stator yoke core cylindrical is first-class to be arranged with and the identical dovetail groove of stator tooth iron core quantity, the microcephaly of each stator tooth iron core is provided with the dovetail head, described each stator tooth iron core is fixed by the mutual joggle of dovetail groove on dovetail head and the stator yoke iron core body, and described solenoid type coil is enclosed within outside the stator tooth iron core.
Described annular stator yoke core is made up of the mutual front and back of some identical stator yoke iron core units joggle, is respectively equipped with joggle and joggle groove before and after each stator yoke iron core unit.
Described solenoid type coil is divided into plurality of sections, and its quantity is consistent with the quantity of stator yoke iron core unit.
The utility model product structure is simple, production cost is low, long service life, the operating efficiency of generator of having improved, can guarantee the long-time steady operation of generator, the silicon plate utilance is up to 95%, and coiling process enamelled wire, paint film can not damage, the product qualified rate height, reliable in quality.
