Abstract
The utility model relates to an iron core lamination for a high power permanent magnet aerogenerator, which is formed by combination of a plurality of identical lamination components, wherein, the lamination components have sector annular shapes; a plurality of slots for embedding leads of an armature winding of the stator are arranged evenly along the inner camber of the lamination components; and two sides of the lamination components have shapes matched with adjacent edges of adjacent lamination components to form the slot shape. Compared with the prior art, the iron core lamination significantly reduces the startup drag torque of the permanent magnet aerogenerator and realizes low wind speed startup and low wind speed cut-in.
Description
Technical field
The utility model relates to the generator punching, particularly relates to a kind of core stamping that is used for the high-power permanent magnet wind-driven generator.
Background technology
Electro-magnetic motor is to produce magnetic field by exciting current, thereby magnetic field can carry out outside regulation and control by exciting current, so magnetic field intensity can be very little during the asynchronous wind driven generator starting, reduces the starting reactance square, is easy to start.But the magnetic pole of permanent-magnetic wind driven generator is made by permanent magnetic material, and its magnetic field intensity can't be regulated, thus should make the starting reactance square as far as possible little from other technologies, so that low wind speed starts and builds and press power supply.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of core stamping that is used for the high-power permanent magnet wind-driven generator simple in structure for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of core stamping that is used for the high-power permanent magnet wind-driven generator, it is characterized in that, constitute by several pieces identical punching component amalgamations, described punching component is fan-shaped ring, prolong its inner arc and evenly offer the groove that several are used to pacify embedding stator armature winding conducting wire, the both sides of each punching component all are the shape that can piece together above-mentioned groove with the adjacent edge of adjacent punching component.
Evenly offer several location and fixing hole on the described punching component.
Described core stamping is made of 15 identical punching component amalgamations, and its external diameter is 3120mm, and internal diameter is 2800mm, the radian of each punching component is 24 °, groove on described each punching component is 20, and is uniformly distributed on the punching component by 360 °/315, and the length of each groove is 100mm.
Described location and fixing hole are 3 holes that diameter is 20mm.
Compared with prior art, the utility model greatly reduces the resistance of start square of permanent-magnetic wind driven generator, realizes low wind speed startup and hangs down the wind speed incision.
Fig. 1 is the structural representation of punching component of the present utility model;
Wherein: 1-punching component, 2-groove, 3-location and fixing hole.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of core stamping that is used for the high-power permanent magnet wind-driven generator, constitute by several pieces identical punching component 1 amalgamations, described punching component 1 is fan-shaped ring, prolong its inner arc and evenly offer the groove 2 that several are used to pacify embedding stator armature winding conducting wire, the both sides of each punching component 1 all are the shape that can piece together above-mentioned groove 2 with the adjacent edge of adjacent punching component.
Evenly offer several location and fixing hole 3 on the described punching component 1; Described core stamping is made of 15 identical punching component 1 amalgamations, its external diameter is 3120mm, internal diameter is 2800mm, the radian of each punching component 1 is 24 °, groove 2 on described each punching component 1 is 20, and be uniformly distributed on the punching component by 360 °/315, the length of each groove 2 is 100mm; Described location and fixing hole 3 are 3 holes that diameter is 20mm.
Present embodiment is the core stamping that is used for the permanent-magnetic wind driven generator of 1MW, this core stamping is an external diameter 3120mm, and the part of the garden ring of internal diameter 2800mm is encircled into an external diameter 3120mm by 15 altogether, the garden ring of internal diameter 2800mm, every contained radian is 240.
Location and fixing hole that 3 Ф 20 are arranged on this core stamping, bolt pass these location and fixing hole is fixed on this core stamping on the generator unit stator shell.And being encircled into external diameter 3120mm, the garden of internal diameter 2800mm is encircled.
Have on this core stamping by 20 of the grooves of 360 °/315 equally distributed long 100mm, in addition punching about the outside respectively have half groove in opposite directions, every two-phase to face the synthetic complete groove of punching half.
This core stamping is the significant components of 1MW magneto alternator stator, and its material is a high-quality silicon steel, is good electromagnetic material, and the groove in its punching is the groove of the opening of peace embedding stator armature winding conducting wire.
The number of stator slots of present embodiment is 315 grooves, and number of magnetic poles is 104 utmost points, because of
Be mark, so this 1MW stator is a fractional-slot.Can reduce the high order harmonic component of induced electromotive force, and the starting reactance square is reduced, will make promptly that every groove number that occupies mutually is a mark under each magnetic pole, rather than integer, cooperate the size of selecting suitable air gap just can realize low wind speed starting again and hang down wind speed and cut.
