Abstract
The utility model relates to DC electromotor part, in particular to a brush-less DC electromotor stator used in an electric vehicle which is assembled by a plurality of stator gear units; one side surface at the inner round end of the stator gear unit is provided with a gibbosity; the other side surface is provided with a concave hole; the gibbosity of each stator gear unit is embedded in the concave hole of the neighboring stator gear unit and assembled into the brush-less DC electromotor stator used in an electric vehicle. The brush-less DC electromotor stator has a simple structure and is designed reasonably; leads can be arranged in order compactly; the thankful rate is high; the end parts of a winding is small as well; the resistance of the winding is small; the loss when running is small; the efficiency can reach 82 to 85 percent.
Description
Technical field
The utility model relates to a kind of DC motor parts, especially electric vehicle brushless DC motor stator.
Background technology:
The DC motor that adopt two types of electric motor car at present: a kind of is that the brush DC motor is arranged, and another kind is a brushless DC motor more.The efficient of these two kinds of motor is normally at 72-76%.What their adopted all is traditional monolithic devices punching, and the copper factor of winding rule is not high, and its rotor punching (the brush DC motor is arranged) or its stator punching (brushless DC motor) stack, or sticking glutinous or riveted joint or be welded into a complete iron core.Adopting this traditional whole punching, though performance is pretty good, if think further to improve its efficient, is impossible basically.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of electric vehicle brushless DC motor stator.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric vehicle brushless DC motor stator, form by a plurality of stator tooth unit splicings, side at the interior nose circle of stator tooth unit is provided with dome, the another side has shrinkage pool, and the dome of each stator tooth unit is flush-mounted in assembled electric vehicle brushless DC motor stator in the shrinkage pool of adjacent stators tooth unit.
Further: the stator tooth unit by stator punching in accordance with regulations size stack or sticking glutinous or riveted joint or be welded.
Further: the quantity of stator tooth unit is 24.
The utility model is simple in structure, reasonable in design, because stator is to be formed by the stator tooth unit splicing, before assembly unit, directly wind the line on the stator tooth unit, lead can marshalling, compactness, copper factor height, and winding overhang is also little, because copper factor height, end weak point, so winding resistance is little, during operation the consume little, efficient can be up to 82-85%.
Description of drawings
The utility model is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of stator tooth of the present utility model unit.
Among the figure: 1, stator tooth unit, 2, dome, 3, shrinkage pool, 4, stator punching.
Embodiment
A kind of electric vehicle brushless DC motor stator as shown in Figure 1 and Figure 2, assembled by 24 stator tooth unit 1, side at the interior nose circle of stator tooth unit 1 is provided with dome 2, the another side has shrinkage pool 3, and the dome 2 of each stator tooth unit is flush-mounted in assembled electric vehicle brushless DC motor stator in the shrinkage pool 3 of adjacent stators tooth unit.Stator tooth unit 1 by stator punching 4 in accordance with regulations size riveted joint stack, before the assembly unit, directly on the stator tooth unit, wind the line, dome on the stator tooth unit is flush-mounted in the shrinkage pool of adjacent stators tooth unit and is assembled into a complete integral body, at last with epoxy with stator solid Feng Chengyi insulation, protection against the tide, waterproof and dustproof and the very high integral body of mechanical performance.
Claims (3)
1, a kind of electric vehicle brushless DC motor stator, it is characterized in that: assembled by a plurality of stator tooths unit (1), side at the interior nose circle of stator tooth unit (1) is provided with dome (2), the another side has shrinkage pool (3), and the dome of each stator tooth unit (2) is flush-mounted in assembled electric vehicle brushless DC motor stator in the shrinkage pool (3) of adjacent stators tooth unit.
