Abstract
The utility model relates to a novel rotor iron core for vehicle motors. The utility model discloses a novel rotor iron core for vehicle motors, comprising a rotor iron core body, cast aluminum grooves, a central axle hole and a key hole, wherein a plurality of cast aluminum grooves are arranged at the outer edge of the rotor iron core body and are uniformly distributed with the center of the rotor iron core as a circle center, the central axle hole is arranged in the middle part of the rotor iron core body, and the key hole is arranged at the inner edge of the rotor iron core body. The novel rotor iron core for vehicle motors is characterized in that the outer diameter of the rotor iron core body is 134.9-135.2mm and the inner diameter of the rotor iron core body is 48.00-48.02mm. The utility model aims to further improve the structure of the rotor iron core for vehicle motors and to solve the problem of use inconvenience caused by unreasonable design of the structures of existing rotor iron cores for vehicle motors.
Description
Technical field
The utility model belongs to the electric motor of automobile technical field, is specifically related to novel electric motor of automobile rotor core.
Background technology
Electric automobile refers to travel with power wheel take vehicle power as power, meets the vehicle of road traffic, safety regulations requirements.Because less to the relative orthodox car of environmental impact, its prospect is extensively had an optimistic view of, but current techniques is still immature.
Electric motor of automobile uses rotor core as a critical component of electric motor of automobile, and its structural design is very large on the impact of electric motor of automobile performance.Yet, now present, electric motor of automobile adopts the general purpose motor structure of rotor core mostly with the structure of rotor core, its structural design is comparatively complicated, and, its size does not meet the requirement of electric motor of automobile design yet, therefore adopt the electric motor of automobile performance of this rotor core not satisfy the requirement of electric automobile, uses very uncomfortable.
The utility model content
The purpose of this utility model: unreasonable and bring awkward problem with the rotor core structure design to solve existing electric motor of automobile in order further to improve electric motor of automobile with the structure of rotor core, and novel electric motor of automobile rotor core is proposed.
The technical solution of the utility model: novel electric motor of automobile rotor core comprises rotor core main body, aluminum cast groove, central shaft hole and keyhole; The outer ledge of rotor core main body arrange aluminum cast groove several, and aluminum cast groove evenly distributes as the center of circle take the center of rotor core main body; Central shaft hole is arranged at the middle part of rotor core main body; Keyhole is arranged at the inside edge of rotor core main body, it is characterized in that: the external diameter of described rotor core main body is 134.9mm～135.2mm; The internal diameter of described rotor core main body is 48.00mm～48.02mm.
Novel electric motor of automobile rotor core of the present utility model, during assembling, it conforms to the matching requirements of electric motor of automobile, therefore when using, electric motor of automobile has preferably performance, and such structural design is not only so that the performance of electric motor of automobile can satisfy the requirement of electric automobile, and, very easy to use.
Further, described aluminum cast groove arranges 32, and the size of described aluminum cast groove is by little gradually large, again by greatly gradually little.
Be can improve the cast aluminium amount again by large gradually little structure gradually greatly by little with the size design of aluminum cast groove, thereby improve the performance of electric motor of automobile.
Further, described keyhole arranges 1, and keyhole is wedge shape.
The keyhole of wedge structure, so that armature spindle and rotor core main body can be fitted closelyr, thereby, so that the transmission performance of electric motor of automobile is better.
Description of drawings
Fig. 1 is the cross section structure schematic diagram that novel electric motor of automobile of the present utility model is used the embodiment of rotor core;
Fig. 2 is the end view that novel electric motor of automobile of the present utility model is used the embodiment of rotor core.
Embodiment
As depicted in figs. 1 and 2, the utility model provides novel electric motor of automobile rotor core, comprises rotor core main body 1, aluminum cast groove 2, central shaft hole 3 and 1 wedge shape keyhole 4; The outer ledge of rotor core main body 1 arranges 32 aluminum cast grooves 2, and the size of aluminum cast groove 2 is by little gradually large, and again by greatly gradually little, aluminum cast groove 2 evenly distributes as the center of circle take the center of rotor core main body 1; Central shaft hole 3 is arranged at the middle part of rotor core main body 1; Keyhole 4 is arranged at the inside edge of rotor core main body 1, and wherein, the external diameter of rotor core main body 1 is: D2=134.9mm～135.2mm; The internal diameter of rotor core main body 1 is: D1=48.00mm～48.02mm.
In the present embodiment, this novel electric motor of automobile with the length of rotor core is: L=145mm～155mm.
Aluminum cast groove 2 is arranged 32, and be mainly to consider the actual conditions of electric motor of automobile again by large gradually little structure gradually greatly by little with its size design, consider the cast aluminium amount of aluminum cast groove 2 in addition, thereby improve the performance of electric motor of automobile, satisfy the instructions for use of electric automobile.
In addition, keyhole 4 is arranged 1, and it is designed to wedge shape, mainly consider the applying degree of armature spindle and rotor core main body 1, thereby so that electric motor of automobile has preferably transmission performance.
Above-described only is preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
