The accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the STRUCTURE DECOMPOSITION figure of the motor that provides of the utility model embodiment.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
The utility model embodiment provides a kind of fan motor, referring to Fig. 1, described fan motor comprises motor back cover 1, is connected in the motor shaft 2 of motor back cover 1, the order motor front shroud 8 that is arranged at the first coil holder 3 on motor shaft 2, rotor 4, stator 5, the second coil holder 6, the PCB connecting plate 7 be connected with the second coil holder 6, matches with motor back cover 1 successively.
Particularly, the first coil holder 3 is connected with stator 5 by the first stator slot, and the first coil holder 3 comprises the first coil holder body 31, is arranged at the first coil holder groove 32 on the first coil holder body 31, and copper cash passes through from the first coil holder groove 32 the insides, withstand voltage, resistance to sparking can be better, and motor is more stable.
Particularly, rotor 4 is the rotor that integrated pouring forms, and makes the parameter of electric machine more stable, and magnetic flux is more stable, and electrical machinery life is longer.
Particularly, stator 5 comprises stator body 51, is symmetricly set in the first stator slot (not shown) and second stator slot 52 of stator body 51 both sides.
Particularly, the second coil holder 6 is connected with stator 5 by the second stator slot 52, and the second coil holder 6 comprises the second coil holder body 61, is arranged at the second coil holder groove 62 on the second coil holder body 61, and copper cash passes through from the second coil holder groove 62 the insides, withstand voltage, resistance to sparking can be better, and motor is more stable.
Particularly, PCB connecting plate 7 is fixed in the second coil holder 6 by the second coil holder groove 62.PCB connecting plate 7 and the second coil holder 6 are fixing, and wiring is firm, makes motor more easily produce, install, and reduces the motor scrappage, has advantages of that motor convenient for maintaining cost is low.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: adopt the frequency conversion motor structure without Hall element, PCB connecting plate and the second coil holder are fixed, and wiring is firm, make motor more easily produce, install, reduce the motor scrappage, electrical machmary maintenance is convenient, with low cost.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
