Abstract
The utility model relates to a stator for the capacitance electric motor for the electric fan which comprises a stator chip and a winding, wherein the painted wire of the winding adopts the painted aluminum wire and the diameter of the painted aluminum wire is 120%-140% of the painted copper wire. The utility model can greatly reduce the product cost and the electromagnetic performance maintaining the winding is the same with the present product.
Description
Technical field
The utility model relates to a kind of family expenses or industrial small-power fan stator of condenser type motor that is applicable to.
Background technology
At present the stator winding of the capacitor-operated motor in the same industry all adopts enamel covered wire, is that the plurality of advantages owing to copper cash is good as ductility, good conductivity or the like determines.But present international level, the price of copper material rises steadily, and in order to reduce manufacturing cost, needs to adopt the low material of other price to replace enamel covered wire and can make the electromagnetic performance of winding unaffected.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provide a kind of can reduce cost and also the impregnable fan of performance with the stator of condenser type motor.
The purpose of this utility model is achieved in that the utility model comprises stator chip and winding, and the enamelled wire of described winding adopts enamel insulated aluminium wire, and the line of enamel insulated aluminium wire directly is the 120%-140% in the line footpath of enamel covered wire.
The line of enamel insulated aluminium wire directly be preferably enamel covered wire line footpath 130%.
Technique effect of the present utility model is:
1, the utility model adopts enamel insulated aluminium wire to replace enamel covered wire, greatly reduces the cost of product.
2, the utility model has carried out calculating again to the stator winding parameter of motor according to some characteristics of aluminum steel, determine new winding parameter, the line that is enamel insulated aluminium wire directly is the 120%-140% in the line footpath of enamel covered wire, the best is 130%, so just can solve the problem of current density, determine the number of turn of winding on this basis again, thereby make the electromagnetic performance of winding keep consistent with existing product.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the three-dimensional exploded view of two embodiment of the utility model.
Embodiment
As shown in Figure 1, two embodiment as described below comprise stator chip 1 and winding 3, are provided with slot for winding 2 on stator chip 1, and winding 3 is embedded in the slot for winding 2, and the enamelled wire of winding 3 adopts enamel insulated aluminium wire.
Embodiment one:
Embodiment one is at a 20 " case fan promptly 20 " exhaust ventilation fan and developing.
The parameter of prior motor stator winding is:
The main winding parameter is: φ 0.24mm/390, and the 79g copper cash,
The auxiliary winding parameter is: φ 0.17mm/300+85+135,53g copper cash.
The parameter of embodiment one stator winding is:
The main winding parameter is: φ 0.30mm/345, and the 38g aluminum steel,
The auxiliary winding parameter is: φ 0.22mm/255+75+115,25g aluminum steel.
Adopt the motor (being called for short " improvement motor ") of embodiment one stator to be compared as follows table: the performance of full load operation test fan, 120V/60Hz with above-mentioned existing motor properties
| Gear | Present motor | The improvement motor | ||||||
| Electric current A | Power W | Rotating speed RPM | Temperature rise K | Electric current A | Power W | Rotating speed RPM | Temperature rise K | |
| High-grade | 0.76 | 88 | 670 | 70 | 0.76 | 89 | 680 | 73 |

| Low-grade | 0.43 | 51 | 350 | 59 | 0.44 | 53 | 360 | 62 |
From last table as seen: keeping under the situation of existing performance, adopting embodiment one can save copper cash 79+53-(38+25)=69g, reaching 69/132=52.3%.
Embodiment two: at a 9 " Industrial fan and developing.
The parameter of prior motor stator winding is:
The main winding parameter is: φ 0.17mm/620, and the 41g copper cash,
The auxiliary winding parameter is: φ 0.14mm/445+210+235,41g copper cash.
Fresh sample motor stator winding parameter is:
The main winding parameter is: φ 0.22mm/620, and the 22g aluminum steel,
The auxiliary winding parameter is: φ 0.18mm/330+160+175,17g aluminum steel.
Adopt the motor (being called for short " improvement motor ") of embodiment two stators to be compared as follows table: the performance of full load operation test fan, 120V/60Hz with above-mentioned existing motor properties
| Gear | Present technology | Improving technology | ||||||
| Electric current A | Power W | Rotating speed RPM | Temperature rise K | Electric current A | Power W | Rotating speed RPM | Temperature rise K | |
| High-grade | 0.44 | 52 | 2400 | 66 | 0.4 | 48 | 2390 | 66 |
| Middle-grade | 0.33 | 38 | 1930 | 62 | 0.33 | 39 | 1815 | 61 |
| Low-grade | 0.25 | 27 | 1310 | 58 | 0.26 | 30 | 1250 | 57 |
As seen from the above table: under the situation of the performance of keeping existing product, adopt embodiment two can save copper cash 41+41-(22+17)=43g, reach 43/82=52.4%.
In addition, because the welding performance of aluminum steel is poor, the foregoing description is when solving aluminum steel with technical barrier that lead-out wire is connected, and the employing indirect method welds together lead-out wire and enamel insulated aluminium wire, and is quick and practical.
The 120%-140% in the line footpath of enamel covered wire can be adopted in the line of enamel insulated aluminium wire footpath in the utility model.
