At assembling time, the silicon steel sheets are respectively stamped to form the stator sheets with tooth inserting grooves and insertion tooth sheets, the stator sheets and the insertion tooth sheets are respectively aligned and stacked to form the stator and insertion teeth, the stator and the insertion teeth are placed into formed windings one by one, and the stator can be formed as long as the insertion teeth are hit into the tooth inserting grooves. The motor gear shaping stator has the advantages of being exquisite in conception, reasonable in structure and simple in inserting coil technology. Especially, the stator guide line notch can be opened larger, automatic inserting coil of machines can be met, and the groove full rate is improved, subsequently, the insertion teeth are used for blocking open guide line grooves, so that the clearance between adjacent stator teeth is reduced, and the motor performance is improved.
Description
Technical field:
The invention belongs to machine field, particularly a kind of gear shaping stator, utilizes gear shaping to improve the copper factor of stator and the assembly technology of this gear shaping stator.
Background technology:
Raising power of motor density, high density, high efficiency, high torque (HT) are one of leading indicators of passing judgment on by motor.The copper factor of the stator winding of high density motor is higher, but in order to make the magnetic flux density of each magnetic circuit of stator suitable, should guarantee the width of stator tooth.In order to reduce the loss of electric machine, often the notch design of stator slot is less, and this just brings difficulty to winding inserting, especially adopts the thread whole winding of multiturn flat copper, rolls off the production line more difficult, or cannot roll off the production line at all.Traditional stator manufacturing process, the stator flat type copper wire winding of high copper factor needs open slot or semi-open slot, but motor slot is too large, and motor gas-gap magnetic flux distribution is uneven, and slot ripples increases, and supplementary load loss increase, and electric efficiency declines.How to improve the contradiction of existing stator copper factor and notch, become the object of the present invention's research.
Summary of the invention:
The object of the invention is to invent a kind of stator teeth and offer inserted tooth groove, utilize gear shaping to embed in inserted tooth groove, dwindle gear shaping stator and the assembly technology thereof of notch.
Technical solution of the present invention is achieved in that a kind of gear shaping stator, it is characterized in that all offering inserted tooth groove on each tooth of dynamo sheet stator, each inserted tooth groove sets the gear shaping of a silicon steel sheet, described gear shaping has the T connector of an arc surface, gear shaping embeds in inserted tooth groove, and this T connector is the opening metallic channel of shutoff both sides respectively, between the T connector of adjacent gear shaping, has gap, form notch, the arc surface of a plurality of T connectors forms inner circle or the cylindrical structure of stator.
Described inserted tooth groove both sides are processed with respectively anticreep pawl, de-pawl can be one or more, and described gear shaping both sides outline and inserted tooth groove coincide, and corresponding anticreep pawl position is provided with sets one's teeth on edge, after embedding, gear shaping by anticreep pawl and coordinating of setting one's teeth on edge, forms gear shaping disconnecting prevention structure.
An assembly technology for gear shaping stator, is characterized in that comprising the steps:
One, silicon steel sheet is gone out respectively some with the stator piece of inserted tooth groove and metallic channel with pressing equipment, and stator piece is aimed at and is stacked, and is combined into integral body;
Two, silicon steel sheet with pressing equipment go out respectively some with setting one's teeth on edge, the gear shaping sheet of cambered surface, gear shaping sheet is aimed at and is stacked, and is combined into strip, thickness equates with stator, the number of teeth equates with groove number;
Three,, by the good moulding winding of coiling, put in the stator conductor groove with inserted tooth groove;
Four, in inserted tooth groove, squeeze into strip gear shaping one by one, complete stator assembly process.
The present invention is skillfully constructed, rational in infrastructure, the simple feature of inserting-coil process; What especially stator conductor notch can be opened is larger, meets machine and automatically rolls off the production line, and improves copper factor, then by gear shaping shutoff notch, dwindles the air gap of adjacent stators tooth, improves motor performance; And by corresponding assembly technology, can realize fast assembling.
