Abstract
A double three-phase direct-drive permanent- magnet wind-driven generator comprises a stator and a rotor, wherein 2 sets of three-phase windings identical in structure and un-staggered electrical angle in time are arranged on the stator, and connected with 2 groups of three-phase converter units identical in time phase respectively, and the electrical parameters of the 2 sets of three-phase windings are identical in both phase and amplitude of time. The double three-phase direct-drive permanent-magnet wind-driven generator provided by the utility model has simple and compact structure and low manufacturing cost, and can work stably and reliably. As the 2 sets of three-phase windings are connected with the 2 groups of three-phase converters units identical in time phase respectively, one set of motor three-phase winding can be independently operated with one set of three-phase converter unit, thereby facilitating the overcoming of the defect that when partial winding is damaged, the motor can't operate or can only operate with low performance, and ensuring the operating performance of the motor, and solving the problem that the overcurrent of a low-pressure high-capacity conversion system is influenced by the limit value of a component.
Description
Technical field
The utility model relates to a kind of direct-drive permanent magnet wind power generator, more particularly, relates to a kind of pair of three-phase direct-drive permanent magnet wind power generator.
Background technology
Motor commonly used is as long as any one winding damages, just can not normally move or because of mis-behave can not long-time running.The big capacity converter system of low pressure overcurrent is easy to surpass the overcurrent limit value of components and parts, and components and parts are fragile, therefore, often needs more components and parts in parallel or improves the radiating condition of components and parts, like this, can cause increasing considerably of manufacturing cost.
Chinese patent 200410053931.4 discloses a kind of double three-phase permanent-magnetic synchronous machine, and stator is provided with the winding of the electrical degree that staggers on the 2 cover spaces, and 2 cover windings connect the three phase mains that two groups of time phase differences are 30 degree respectively.Its groove number that requires the every extremely every phase of winding must be an even number, this structure and be not suitable for multipole few groove, every extremely every phase groove number is the generator system of odd number, the scope of application is little.
The utility model content
The purpose of this utility model is to provide a kind of low cost of manufacture, two three-phase direct-drive permanent magnet wind power generators applied widely.
The purpose of this utility model is achieved through the following technical solutions: it comprises stator and rotor, stator is provided with do not stagger on identical and time three phase windings of electrical degree of 2 nested structures, 2 the cover three phase windings connect respectively 2 groups time phase identical 3-phase power converter unit, 2 cover three-phase winding electric parameters phase place in time is identical, and temporal amplitude is also identical.
Described 2 covers, the three phase windings 180 degree mechanical angles that stagger on 180 degree electrical degrees or the spaces that spatially stagger.
2 covers, three phase winding neutral points do not connect, and do not have the passage of electricity between 2 covers, the three phase winding neutral points, and the rotating magnetic field direction that produces during the work of 2 covers, three phase windings is identical.
Use above-mentioned principle, greater than 2 direct-drive permanent-magnetism motor, it can be extended to many three-phases for generator way in parallel.
The utility model is simple in structure, compact, low cost of manufacture, working stability is reliable, applied widely, 2 covers, three phase windings connect respectively 2 groups time phase identical 3-phase power converter unit, but single cover motor three phase windings and the isolated operation of 3-phase power converter unit, help eliminating motor when the part winding damages, can not move or the defective of low performance operation, help ensureing the runnability of motor, solve the problem that the big capacity converter system of low pressure overcurrent is influenced by the components and parts current limit.
