Abstract
The utility model relates to a motor tooth-inserting stator which is characterized in that each stator tooth of a silicon-steel-sheet stator is provided with a tooth-embedding groove; each tooth-inserting groove is equipped with a silicon-steel-sheet insert tooth which is provided with a T-type head with an arc surface; the insert teeth are embedded into the tooth-embedding grooves; the T-type heads block opening wire grooves at the two sides respectively and gaps exist between T-type heads of adjacent insert teeth so that grooves are formed. The arc surfaces of the plurality of T-type heads are combined to form an inner or outer circumferential structure. The tooth-inserting stator has the characteristics of being clever in idea, reasonable in structure and simple in wire inserting process; particularly, the stator wire grooves can be larger so that machine automatic wire inserting can be satisfied and thus groove filling factor is improved; and then the insert teeth are used to block the opening wire grooves so that gaps between adjacent stator teeth are reduced and motor performance is improved.
Description
Technical field:
The utility model belongs to machine field, and particularly a kind of gear shaping stator, utilizes gear shaping to improve the copper factor of 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 the 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 overall 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, motor gas-gap magnetic flux distribution inequality, 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 utility model research.
Summary of the invention:
The purpose of this utility model is that a kind of stator teeth of design offers inserted tooth groove, utilizes gear shaping to embed in inserted tooth groove, dwindles the gear shaping stator of notch.
Technical solutions of the utility model are 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 arranges 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, inner circle or the cylindrical structure of the arc surface composition stator of a plurality of T connectors.
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.
The utility model 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 metallic channel, dwindles the gap of adjacent stators tooth, improves motor performance.

Embodiment:
With reference to Fig. 1, Fig. 2 and Fig. 3, gear shaping stator, all offers inserted tooth groove 12 on each stator tooth 11 of its stator 1, and inserted tooth groove 12 both sides are processed with respectively anticreep pawl 13; Each inserted tooth groove 12 arranges a gear shaping 2, T connector 21, both sides outline and inserted tooth groove 12 that gear shaping 2 has an arc surface coincide, corresponding anticreep pawl 13 positions are provided with sets one's teeth on edge 22, after gear shaping 2 embeds by anticreep pawl 13 with set one's teeth on edge 22 coordinate, formation gear shaping 2 disconnecting prevention structures; Gear shaping 2 embeds in inserted tooth groove 12, this T connector 21 metallic channel 10 of shutoff both sides respectively, and 21 of the T connectors of adjacent gear shaping have gap, form notch, the inner circle structure of the arc surface composition stator of a plurality of T connectors 21.
If motor is outer-rotor structure, inserted tooth groove is on stator excircle so, and the arc surface of the T connector 21 of a plurality of gear shapings forms the cylindrical structure of stator.
As Fig. 2, during assembling, first embed overall winding 3, the then gear shaping 2 inserted tooth groove 12 that aligns, towards radially squeezing in this inserted tooth groove 12, utilizes the notch of the metallic channel 10 of the T connector 21 shutoff both sides of gear shaping.
