Abstract
The utility model discloses a special-shaped outer stator core of an automobile generator. The utility model is characterized in that adjacent stator grooves have different shapes; for a kind of stator grooves, a groove bottom is wider than a groove face; for another kind of stator grooves, a groove face is wider than a groove bottom; every other groove has the completely same groove shape; centre distance of each groove notch is equal, and the central distance for adjacent stator teeth is different; the stator teeth are changed to form an inclined shape, and the width of each of the teeth is basically remained unchanged; consequently, both sides of armature winding coils are arranged in a position which is wider in the grooves. The outer stator core with the adoption of the structure has the advantages of large fill factors of the grooves and high rate of groove utilization. Through further improvement in the performance of the generators of the outer stator core, output power can reach multikilowatt.
Description
The utility model relates to the special external stator core for automobile generator of a kind of structure, and the external stator core of this abnormity is applicable on the generator of various automobiles, tractor.
In order to adapt to the needs of current automobile, tractor development, we once designed a kind of automobile current generator of big specific power, to Patent Office of the People's Republic of China's application patent of invention, its number of patent application is 90 1 00649.1, it adopts the external stator core yoke portion that dwindles, shorten stator tooth, the internal diameter that increases external stator core keeps external diameter constant simultaneously, the external diameter and the internal diameter ratio of external stator core are reduced, this generator does not increase the power output that increases generator under the raw-material situation significantly in constant overall dimension.But the flute profile of this external stator core is mostly taked peariform slot or rectangular channel, and monolateral coil and single layer winding structure reduce the utilance of groove in the groove, and activity coefficient reduces, and the performance that influences generator is to a certain extent further improved.
Task of the present utility model is the external stator core that proposes a kind of and regular groove different structure, this external stator core had both kept the characteristics that stator tooth shortens, stator slot shoals, can increase the activity coefficient of groove again, improve the utilance of groove, thereby make AC generator for vehicle performance be improved significantly, increase power output.
The utility model is finished in such a way, the groove of the external stator core of this generator is inequality with regular stator slot commonly used, this stator slot is that bottom land and groove face are different wide, and adjacent stator slot shape is different fully, wherein there is a kind of bottom land of stator slot wideer than groove face, then groove face is wideer than bottom land for the another kind of stator slot that is adjacent, the flute profile of the groove in every interval is identical, therefore the stator slot of this external stator core is divided into two big classes, and the stator slot of these two big classes respectively accounts for half.The notch centre-to-centre spacing of each groove is equal fully, and adjacent stator tooth centre-to-centre spacing is unequal, but the stator tooth centre-to-centre spacing of the tooth in space equates.Stator tooth constitutes oblique shape, and the width of stator tooth remains unchanged substantially.The external stator core of this polymorphic structure, the both sides of armature winding coil all are the positions that is placed on stator slot internal ratio broad, and coil relatively is full of in stator slot like this, and reduce in the space in the groove, and the activity coefficient of groove is increased, and the utilance of groove improves.The design of this external stator core, can accomplish that stator tooth shortens, the requirement that stator slot shoals can select for use thicker lead to use as armature winding again, AC generator for vehicle adopts performance significant performance after this external stator core structure, and power output increases greatly.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is an external stator core cutaway view of the present utility model.
Fig. 2 is adjacent two stator slot enlarged diagrams of the present utility model.
Fig. 1 illustrates the external stator core (1) of this abnormity, stator slot (4) and (5) that two kinds of different sizes are arranged between this external stator core yoke portion (2) and the stator tooth (3), their bottom land and groove face are different wide, the bottom land of stator slot (4) is wideer than groove face, the groove face of stator slot (5) is then wide than bottom land, and groove (4) and groove (5) are adjacent.It can also be seen that from figure the stator slot shape of the groove of whenever being separated by is just the same, so these grooves have half identical with stator slot (4) shape, half is then identical with groove (5) shape in addition.The notch of these stator slots (6) centre-to-centre spacing is equal fully, but stator tooth (3) centre-to-centre spacing equates not necessarily that then adjacent stators tooth centre-to-centre spacing is unequal, and the stator tooth centre-to-centre spacing of the tooth of being separated by is identical.Fig. 2 is the enlarged drawing of stator slot (4) and (5), and the bottom land of stator slot (4) is wideer than groove face, and the armature winding coil just is placed on the bottom land, and the groove face of stator slot (5) is wideer than bottom land, and the armature winding coil but is placed on the groove face.So adopt the external stator core of this polymorphic structure, owing to continued to keep these characteristics of internal diameter of increase external stator core (1), the magnetic flux of each magnetic pole of rotor is increased, just can select the bigger armature winding of sectional area of wire for use, output current is increased and current density remains unchanged substantially, the both sides of all armature winding coils can be placed on the position of groove internal ratio broad respectively, and the utilance of groove and activity coefficient increase.The impedance of this armature winding is little, and the main flux of rotor magnetic pole is big, can reach multikilowatt so the power output of this AC generator for vehicle enlarges markedly.
Claims (1)
