The utility model discloses the cross sectional shape of stator slot sets up to the rectangle to, the cross sectional shape of wire sets up to the rectangle, so, with original stator slot area condition of being close under can reach the full rate in higher groove to make the motor reach higher energy density.
Description
Technical field
The utility model relates to plant equipment, in particular a kind of brushless electric machine winding structure of novel unmanned plane.
Background technology
In prior art, current unmanned plane industry generally adopts BLDC (brshless DC motor) for providing power, existing brshless DC motor as shown in Figure 1, the cross sectional shape of the stator slot 102 of motor stator 103 is set to trapezoidal, and the enamel covered wire 101 using cross section to be circle carries out coiling, cause stator slot space availability ratio not high, such as, in the separation of stator slot 102, area is about 24.33mm
2, approximately can move into 147 diameter 0.4mm enamel covered wires 101, its cross-sectional area is added and is about 18.46mm
2, the copper factor of stator slot 102 is 18.46/24.33*100%=76.89%, and therefore, the winding technique of the common enamel covered wire of existing use makes BLDC copper factor on the low side, cannot make the energy density that motor reaches higher.
Therefore, prior art existing defects, needs to improve.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of BLDC copper factor higher, the brushless electric machine winding structure of the novel unmanned plane that motor power density is higher.
The technical solution of the utility model is as follows: a kind of brushless electric machine winding structure of novel unmanned plane, comprise the wire for coiling and motor stator, motor stator is provided with some stator slots for coiling wire, the cross sectional shape of stator slot is set to rectangle, further, the cross sectional shape of wire is set to rectangle.
Be applied to technique scheme, in described brushless electric machine winding structure, wire is set to enamel-cover plain conductor or empire cloth coated metal wire.
Be applied to each technique scheme, in described brushless electric machine winding structure, the cross sectional shape of wire is set to square.
Be applied to each technique scheme, in described brushless electric machine winding structure, the separation area of stator slot is set to 23.53mm
2, in it, be wound with the square enamel covered wire that 14 cross section length of sides are 1.28mm.
Adopt such scheme, the cross sectional shape of the utility model stator slot is set to rectangle, and, the cross sectional shape of wire is set to rectangle, so, higher copper factor can reached with original stator slot area close in situation, thus make the energy density that motor reaches higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is that the local of part A in Fig. 1 sends out figure large;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is that the local of part B in Fig. 2 sends out figure large.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Present embodiments provide a kind of brushless electric machine winding structure of novel unmanned plane, as shown in Figure 3 and Figure 4, brushless electric machine winding structure comprises wire 201 for coiling and motor stator 203, motor stator 203 is provided with some stator slots 202 for coiling wire 201, the cross sectional shape of stator slot 202 is set to rectangle, further, the cross sectional shape of wire 201 is also set to rectangle.
Wherein, wire 201 adopts enamel-cover plain conductor or empire cloth coated metal wire, wherein, wire 201 is preferably set to enamel covered wire, or, different conductor can be used to substitute enamel covered wire and to carry out coiling, such as, use enamel insulated aluminium wire, enamel-cover silver line etc. or change insulating barrier, use empire cloth parcel simple metal wire to carry out coiling etc.The cross sectional shape of wire 201 is preferably set to square.
Such as, be 23.53mm by the separation area of this stator slot 202
2, approximately can move into 14 length of side 1.28mm square enamel covered wires, its cross-sectional area is added about 22.82mm
2, copper factor is 22.82/23.53*100%=96.98%, and comparing original scheme has remarkable lifting.
So, making it closer to rectangle by improving stator slot moulding, using rectangular cross section enamel covered wire to carry out coiling simultaneously, higher copper factor can reached with original stator slot area close in situation, thus make the energy density that motor reaches higher.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
