The utility model reduces the slot density of the stator punching sheet by increasing the included angle between the slots of the stator punching sheet, thereby not only reducing the weight and the heat productivity, but also greatly increasing the heat dispersion by matching with the heat dissipation holes and reducing the wave distortion rate; through setting up the ventilation groove and the ventilation lightening hole of special shape, furthest has alleviateed the weight when guaranteeing stable in structure to furthest has increased the ventilation cooling effect, has reduced the power loss of motor, has improved work efficiency, has prolonged life.
Description
Technical Field
The utility model belongs to the electrical equipment field specifically is a towards piece stator and rotor core.
Background
The permanent magnet motor is a motor which generates a synchronous rotating magnetic field by permanent magnet excitation, the permanent magnet is used as a rotor to generate a rotating magnetic field, and a three-phase stator winding is reacted through an armature under the action of the rotating magnetic field to induce three-phase symmetrical current. The permanent magnet motor is widely used due to the advantages of high efficiency, low energy consumption and the like. The stator punching sheet in the stator and rotor core of the common motor has the advantages that the included angle between the wire grooves is 10-15 degrees, the density is high, the weight is heavy, the heat productivity is high, the ventilation and heat dissipation are poor, and the power loss is high.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a towards piece stator and rotor core.
The technical scheme of the utility model as follows:
the utility model provides a towards piece stator-rotor core, includes stator punching and rotor punching, the stator punching is the ring shape, and the inner week of stator punching evenly is provided with 20 wire casings, and the contained angle between two adjacent wire casing central lines is 18 degrees, is provided with a louvre between two adjacent wire casings.
The punching sheet stator and rotor iron core is characterized in that the wire groove is trapezoidal, and the length of an opening of the wire groove is greater than the length of the bottom of the wire groove.
In the punching stator and rotor core, the length of the opening of the wire groove is 2 times of the length of the bottom of the wire groove.
The punching sheet stator and rotor core is characterized in that 4 ventilation grooves are uniformly formed in the periphery of a stator punching sheet.
The punching sheet stator and rotor iron core is characterized in that the ventilation slots are inverted triangular.
The punching sheet stator and rotor core is characterized in that 4 ventilation lightening holes are uniformly formed in the position between the inner periphery and the outer periphery of a stator punching sheet, and each ventilation lightening hole is formed in the position between two adjacent ventilation grooves.
The punched sheet stator and rotor iron core is characterized in that the ventilation lightening holes are in a sector ring shape.
The beneficial effects of the utility model are as follows: the utility model discloses a towards piece stator rotor core, through increasing the contained angle between the wire casing of stator punching, reduce the wire casing density of stator punching, not only reduced weight, reduced calorific capacity, and cooperate with the louvre greatly increased heat dispersion moreover, reduced the wave distortion rate; through setting up the ventilation groove and the ventilation lightening hole of special shape, furthest has alleviateed the weight when guaranteeing stable in structure to furthest has increased the ventilation cooling effect, has reduced the power loss of motor, has improved work efficiency, has prolonged life.
Drawings
Fig. 1 is a schematic view of a stator lamination of a stator-rotor core of the present invention;
in the figure, 1-stator punching sheet; 2, a wire groove; 3, heat dissipation holes; 4, a ventilation slot; and 5, ventilating lightening holes.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a towards piece stator-rotor core, including stator towards piece 1 and rotor punching, the stator towards piece 1 for circle ring shape, the stator evenly is provided with 20 wire casings 2 towards the interior week of piece 1, and the contained angle between 2 central lines of two adjacent wire casings is 18 degrees, is provided with a louvre 3 between two adjacent wire casings 2. The included angle between the wire grooves of the stator punching sheet is increased, the wire groove density of the stator punching sheet is reduced, the weight is reduced, the heat productivity is reduced, the heat dissipation performance is greatly increased by matching with the heat dissipation holes, and the wave distortion rate is reduced.
The wire casing 2 is trapezoidal shape to the opening length of wire casing 2 is greater than the bottom length of wire casing, and the opening length of wire casing 2 is 2 times wire casing bottom length. Compared with a common wire slot, the design reduces the weight and facilitates wire winding.
The periphery of stator punching 1 evenly is provided with 4 ventilation slots 4, and ventilation slots 4 are the triangle-shaped of falling. 4 ventilation lightening holes 5 are uniformly arranged between the inner periphery and the outer periphery of the stator punching sheet 1, each ventilation lightening hole 5 is arranged between two adjacent ventilation slots 4, and the ventilation lightening holes 5 are in a fan-ring shape. Through setting up the ventilation lightening hole of inverted triangle-shaped's ventilation groove and fan ring shape, the at utmost has alleviateed weight when guaranteeing stable in structure to the at utmost has increased ventilation cooling effect, has reduced the power loss of motor, has improved work efficiency, has prolonged life.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
