Abstract
The utility model discloses a rotor punching piece used for a motor of an electric vehicle, which comprises a rotor punching piece body, wherein the surface of the outer side of the rotor punching piece body is evenly provided with grooves used for installing magnetic steel pieces, the rotor punching piece body is provided with a plurality of holes which are evenly distributed by encircling an installation hole of a main shaft, and the interval distance of each hole is between 1.8mm and 3.8mm. The structure can enhance the efficiency of a magnetic field of the motor, a strong magnetic field action is formed in an interval area of each hole, and the noise of the motor can be lowered to a certain extent.
Description
Technical field
The utility model relates to a kind of rotor punching, specifically refers to the electric vehicle motor rotor punching.
Background technology
Electric motor car becomes everybody the go on a journey main vehicles of usefulness at present, and rotor punching and stator punching are the major critical components of motor.The sub-punching of height transfer of the operating power of motor and key parameters such as noise is very relevant with the structure of stator punching.The common structure of rotor punching distributes for have slot on the punching surface, and such frame mode makes motor-field efficient not high, and motor can produce must noise.
The utility model content
At the defective that exists in the above-mentioned technology, the purpose of this utility model is to provide a kind of electric vehicle motor rotor punching, can improve motor-field efficient, reduces motor noise.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of electric vehicle motor rotor punching, include the rotor punching body, outer surface at the rotor punching body evenly has the groove that is used for installing magnetic links, in the middle of the rotor punching body is spindle mounting hole, the rotor punching body is evenly distributed with several holes around spindle mounting hole, and it is characterized in that: the spacing distance in adjacent two holes is between 1.80mm～3.80mm.
Spacing distance optimum between described adjacent two holes is 2.88mm.
The outer rim distance of described hole and rotor punching body is between 1.80mm～3.80mm.
The outer rim of described hole and rotor punching body is 2.88mm apart from optimum.
Described hole is triangle or pentagon.
Adopt the rotor punching of said structure, on the rotor punching body, be evenly equipped with a plurality of holes, can be according to the hole count of the different set respective number of motor pole number, setting adjacent two hole neighbor distance is between 1.80mm～3.80mm, optimum setting is 2.88mm, this structure can improve motor-field efficient, forms strong the action of a magnetic field in the adjacent area in each hole, and can reduce motor noise to a certain extent.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an another kind of execution mode structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of electric vehicle motor rotor punching, include rotor punching body 1, outer surface at rotor punching body 1 evenly has the groove 11 that is used for installing magnetic links, in the middle of the rotor punching body is spindle mounting hole 2, the rotor punching body is evenly distributed with 6 holes 3 around spindle mounting hole, and the size range of adjacent two hole 3 spacing distances is 1.80mm～3.80mm, and its spacing distance optimum is 2.88mm.The outer rim distance of hole 3 and rotor punching body 1 is between 1.80mm～3.80mm also.Between the outer rim of its mesopore and rotor punching body the distance optimum be 2.88mm.
As shown in Figure 1, 2, described hole 3 is triangle or pentagon or other irregular shapes, and optimum shape is a triangle.This structure can improve motor-field efficient, forms strong the action of a magnetic field in the interval region in each hole, and can reduce motor noise to a certain extent.
