Description
Technical Field
The utility model relates to the technical field of electric machine, especially, relate to an external stator punching of ventilation groove.
Background
The stator punching sheet and the rotor punching sheet are key parts of the motor, and materials, inner circle size, outer circle size, groove shape size and the like of the stator punching sheet and the rotor punching sheet have direct influence on energy consumption, heat dissipation, working efficiency, noise and service life of the motor. In the motor used in the current market, the structure of the stator punching sheet and the structure of the rotor punching sheet are unreasonable, so that the operation parameter indexes of the motor are adversely affected. For example, the stator punching sheet with the publication number of CN205829328U cannot meet the requirements of customers for heat dissipation effect and energy consumption loss, and in order to solve the problem, in the prior art, the ventilation holes are formed in the stator punching sheet, which has an influence on the electromagnetic performance of the stator punching sheet.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve the technical problem that the mode of seting up the ventilation hole on the stator punching can influence the electromagnetic property of stator punching among the prior art, the utility model provides an external stator punching of ventilation groove, it is rational in infrastructure, the radiating effect is good.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an external stator towards piece of ventilation groove, includes towards the piece body, towards a plurality of stator teeth of the even interval distribution of the interior circumference of piece body, forms the wire winding groove between two adjacent stator teeth, and the periphery equipartition towards the piece body has polylith heat dissipation sawtooth structure, and heat dissipation sawtooth structure comprises towards a plurality of intensive short teeth of the outside bellied of piece body, forms U type ventilation groove between the adjacent short tooth, and the outline towards the piece body and the inside shape of motor casing that the stator was installed towards the piece cooperate.
Further, optionally, in each heat dissipation sawtooth structure, the depth of the U-shaped ventilation grooves on the two sides is smaller than that of the U-shaped ventilation groove in the middle.
Further, optionally, the periphery equipartition of towards piece body have four blocks of heat dissipation sawtooth structures.
The beneficial effects of the utility model are that, the utility model discloses an external stator of ventilation duct is towards the piece, a plurality of intensive short teeth have been designed towards the outer fringe of piece to the stator, form U type ventilation duct between the short tooth, the stator is pressed into the casing after making the iron core towards the piece stack, the outline of stator towards the piece cooperatees towards the inside shape of motor casing that the piece was installed to the stator, make casing inner wall and U type ventilation duct constitute the ventilation hole, this kind of external ventilation duct design is more close to the generator outside, more do benefit to heat conduction and heat dissipation, U type ventilation duct design is on the maximum external diameter of stator towards the piece, make ventilation duct quantity and ventilation area maximize, the structural design that ventilation hole was constituteed jointly to stator towards piece and casing is optimized more, make two kinds of parts obtain the ventilation effect simultaneously, whole machine.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the preferred embodiment of the present invention.
In the figure: 1. the punching sheet body comprises a punching sheet body, 2 stator teeth, 3 winding grooves, 4 short teeth, 5U-shaped ventilation grooves.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, is the utility model discloses the preferred embodiment, an external stator punching of ventilation groove, including towards piece body 1, towards a plurality of stator teeth 2 of the even interval distribution of interior circumference of piece body 1, form wire winding groove 3 between two adjacent stator teeth 2, towards the periphery equipartition of piece body 1 has polylith heat dissipation sawtooth structure, and heat dissipation sawtooth structure comprises towards a plurality of intensive short teeth 4 of piece body 1 outside bellied, forms U type ventilation groove 5 between the adjacent short tooth 4, cooperatees towards the outline of piece body 1 and the inside shape of the motor casing that the stator punching installed. In each heat dissipation sawtooth structure, the depth of the U-shaped ventilation grooves 5 at the two sides is smaller than that of the U-shaped ventilation grooves 5 in the middle. Four heat dissipation sawtooth structures are uniformly distributed on the periphery of the punching sheet body 1.
The utility model discloses an external stator towards piece of ventilation groove, a plurality of intensive short teeth 4 have been designed towards the outer fringe of piece to the stator, form U type ventilation groove between the short tooth, the stator is made the iron core towards the piece stack and is impressed the casing, the outline of stator towards piece cooperatees towards the inside shape of the motor casing of piece installation with the stator, make casing inner wall and U type ventilation groove constitute the ventilation hole, this kind of external ventilation groove design is closer to the generator outside, more do benefit to heat conduction and heat dissipation, U type ventilation groove design is on the biggest external diameter of stator towards piece, make ventilation groove quantity and draught area maximize, the structural design that ventilation hole was constituteed jointly to stator towards piece and casing is optimized more, make two kinds of parts obtain ventilation effect simultaneously, whole machine performance advantage obviously promotes.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
