Abstract
The utility model provides a high-efficient electric vehicle stator iron core including a stator, a notch, and stator slots uniformly distributed in the stator, the middle part of the tooth between every two adjacent stator slots in the stator is provided with multiple groups of Hall cells, and Hall elements are arranged inside the Hall cells. According to the utility model, the positions and shapes of the Hall cells are changed, so that the Hall cells can be mounted to the tooth parts, installation is convenient, power is improved by 2-10%, air gap magnetic flux is uniformly distributed, tooth harmonic is reduced, additional loss is reduced, brushless reversion can be better realized, the Hall elements can be prevented from a high temperature, service life is prolonged, and cost is reduced.
Description
Technical field
The utility model relates to the machine field of electric motor car, particularly a kind of electric motor car stator core efficiently.
Background technology
At present, electro-tricycle and electric bicycle, mainly adopt rechargeable battery that power is provided, and the motor of employing is generally brush motor and brushless electric machine, but brush motor carbon brush need to be installed commutate, need to regularly replace carbon brush, easily damage, the life-span is short; And employing brshless DC motor is installed Hall element, can realize brushless commutation, twisting and the more advantage such as climbing capacity is strong, adopted by more consumers.
But the Hall element that existing electric vehicle motor stator core fills, in machine operation process, due to position and the annexation of Hall element in prior art, make its hot soak condition, heat is not volatile, very easily be aging and damage, having increased consumer's use cost.
Therefore, the utility model is to develop on the basis that mainly solves more than currently available technology existence deficiency.
Summary of the invention
The object of utility model is to solve above technical problem, proposes especially a kind ofly to increase work efficiency, easy for installation, energy-saving and cost-reducing electric motor car stator core.
Based on above-mentioned purpose, the technical problem that the utility model solves realizes by the following technical solutions:
A kind of electric motor car stator core efficiently, comprises equally distributed stator slot on stator, notch and stator, on the groove tooth middle part on described stator between every two stator slots, is provided with many group Hull cells, and Hull cell inside is provided with Hall element.
Further, the shape of cross section of described Hull cell is trapezoidal.
The beneficial effects of the utility model are; this patent changes position and the shape of Hull cell, makes it be mounted to groove tooth position, makes easier for installation; power improves 2--10%; air-gap flux is evenly distributed, and slot ripples reduces, and supplementary load loss reduce; better realize brushless commutation; and protection Hall element is avoided the state in high temperature, increases the service life, and reduces costs.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Embodiment
Below, by Figure of description, further set forth the utility model;
Shown in Fig. 1, a kind of electric motor car stator core efficiently, comprise equally distributed stator slot 2 on stator 1, notch 6 and stator, on groove tooth 4 middle parts on described stator 1 between every two stator slots 2, be provided with many group Hull cells 3, Hull cell 3 inside are provided with Hall element 5, make so easy for installation, energy-saving and cost-reducing, raise the efficiency, increase the service life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
