Abstract
A concentrated winding parallel-connected cooling outer rotor permanent-magnet wind-driven generator includes a stator and a rotor, wherein the rotor is arranged on the outer side of the stator, grooves are formed on the stator, two concentrated windings are mounted in every groove, and a first cooling pipeline is arranged at a clearance between the two concentrated windings arranged in the same one groove. The wind-driven generator has the advantages of simple and compact structure, good cooling effect, shorter journey of cooling liquid, and no cooling dead zone; the cooling pipelines are directly contacted with a heating source of a motor, so as to very efficiently and rapidly cool the motor; therefore, the improvement on heat dissipation ability is facilitated, the heat exchange capacity is enlarged, and the unit volume efficiency of the motor can be greatly improved.
Description
Technical field
The utility model relates to a kind of permanent-magnetic wind driven generator, more particularly, relates to a kind of concentrated winding cooling in parallel external rotor permanent magnet wind-driven generator.
Background technology
The loss in motor when operation easily causes the parts heating, and temperature raises, thereby influences motor useful life.Existing external rotor permanent magnet wind-driven generator, the mode by setting up coolant jacket in stator core yoke portion's pipe laying or yoke portion realizes cooling mostly.By said method, what it directly cooled off is electric machine iron core, and the coil heat need pass through heat loss through conduction.It has only a cooling duct, and cooling effectiveness is low, and cooling time is long.
The utility model content
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of cooling effectiveness high concentrated winding cooling in parallel external rotor permanent magnet wind-driven generator.
The technical solution of the utility model is: it comprises stator and rotor, described rotor is located at the stator outside, have groove on the described stator, two concentrated windings all are housed in each groove, the gap between two concentrated windings in same groove is provided with first cooling pipe.
Be provided with coolant jacket between described diameter of stator bore and the stator support, have groove on the coolant jacket internal diameter vertically, the periphery of this groove and stator support constitutes second cooling pipe.
Described coolant jacket and stator support are fixed by the hot jacket interference fit.
Pour into overall fixed by resin glue between described first cooling pipe and the concentrated winding, directly cool off by first cooling pipe and concentrate winding.
The utility model is simple in structure, compact, good cooling results, it is provided with two cooling ducts, the cooling fluid stroke is shorter, does not have the cooling blind area, the cooling duct contacts directly that the motor feels hot source, can very realize cooling effectively and quickly to motor, help improving heat-sinking capability, increase the heat exchange capacity, can increase substantially the motor specific volume power.
