Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of support of motor stator.
Background technology
The stator of motor mainly comprises iron core, enamelled wire winding, also is useful on the insulation framework of insulation iron core and enamelled wire winding.It is circular that iron core is, and circumferentially is evenly equipped with groove and be used to being wound around the winding seat of enamelled wire winding, winding seat and groove are interspersed, and makes adjacent enamelled wire winding have gap.DC brushless motor adopt to concentrate the mode of winding that the enamelled wire winding is wrapped on iron core, if the winding displacement mode is more chaotic, easily and rotor bump, rub, the situation such as cause short circuit, open circuit.Therefore insulation framework being set is mainly to prevent that adjacent enamelled wire winding from causing interference, makes winding displacement more regular.In addition, the lead-out wire of enamelled wire winding need to be welded on to circuit board, by circuit board, switch on power, circuit board generally is fixed on insulation framework.
Existing insulation framework structure is all more numerous and diverse, and a kind of insulation frame for stator [patent No.: 201220448817.1] as Chinese patent provides, comprise the cyclic skeleton body of being made by insulating material, on this skeleton body, has buckle; Described skeleton body comprises the slot liner part, in described slot liner part, forms the backbone winding wire casing; Described insulation framework also comprises the snap close that can be separated with described skeleton body, and described snap close matches with described buckle.By on the skeleton body, buckle being set, and employing snap fit buckle is in the mode of fixing circuit board, make the skeleton body can make the buckle distortion have precompression to fix circuit board to circuit board, firm position, reliability are high, improved the structural behaviour of insulation framework, avoid insulation framework that easy fracture is installed after dipping lacquer, reduced the proportion of goods damageds of insulation framework, reduced motor hidden danger; The structure of skeleton body and snap close is relative with processing technology simple simultaneously, is suitable for actual production.
Although this structure has solved the fixing problem of circuit board, its dividing plate is that relative cyclic skeleton level is protruded, and the diaphragm structure complexity, if dividing plate quantity changes, baffle dimensions also needs to change so, and mould is made again, causes manufacturing cost to increase.
Summary of the invention
The objective of the invention is to have the problems referred to above for existing technology, proposed a kind of support of motor stator simple in structure.
Purpose of the present invention can realize by following technical proposal: a kind of support of motor stator, stator comprises circuit board, iron core in the form of a ring and is wrapped in the some coils on iron core, adjacent windings is separated by the groove on iron core, it is characterized in that, the support of this motor stator comprises the base that is circular, on described base, be fixed with some support columns that can embed in the iron core groove and can intercept adjacent windings, described support column has the upper surface of energy support circuit plate, on the upper surface of at least one support column, is fixed with the keeper of energy fixing circuit board.
Support column embeds in the groove of iron core, makes support and iron core fix.Be wrapped on iron core coil circumferentially spaced apart, support column embeds in the groove of two adjacent windings, and blocking-up two coils contacts, play insulating effect.The upper surface of support column is plane, and circuit board lies on support column, and keeper can locate circuit board be fixed on support.
In the support of above-mentioned motor stator, the cylinder both sides of described support column offer the V-shaped groove of dodging.Because recess space is less, so being set on support column, V-arrangement dodges groove, prevent support column extruding coil.
In the support of above-mentioned motor stator, described base middle part is provided with the back-up ring that is connected mutually with support column.Back-up ring is connected mutually with all support columns, improves firmness and the bonding strength of support column, avoids support column to be offset.
In the support of above-mentioned motor stator, described support column circumferentially is uniformly distributed, and described support column is all corresponding one by one with the number of locations of iron core groove.The support column circumferential arrangement, and every support column all embeds in the groove of iron core, makes iron core relative with support fixing, can not do the relative translation action.
In the support of above-mentioned motor stator, described support column has the six roots of sensation.On iron core, be wound with six coils, between each adjacent windings, have groove, therefore need six roots of sensation support column to coordinate.
In the support of above-mentioned motor stator, on circuit board, offer location hole, described keeper is the locating shaft that diameter is the same with the pore size of location hole, described locating shaft vertically is fixed on upper surface.Locating shaft and location hole closely cooperate, and circuit board relies on locating shaft and support to fix.
In the support of above-mentioned motor stator, on circuit board, offer location hole, described keeper is the buckle boss, described buckle boss can buckle in location hole circuit board and support column are connected to a fixed.The buckle boss can be held in circuit board the support column upper surface after embedding location hole, makes circuit board be not easy to break away from keeper.
In the support of above-mentioned motor stator, described base, support column and keeper are that the manufacture of integral type structure forms.Due to the three, can use the material of same insulating properties, and structure is all fairly simple, so can adopt the integral structure manufacture, is connected firmly, easily manufactured.
In the support of above-mentioned motor stator, described base, support column, keeper all adopt plastic material to make.Plastic material has good insulating properties, intercepts coil, prevents the adjacent windings contact and short circuit.
Compared with prior art, the support of this motor stator has the following advantages:
1. by the support column fixed stator, the keeper fixing circuit board, play insulating effect simultaneously, prevents coil short, opens circuit.
2. whole supporting structure is simple, and is easy to make.
