Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of water pump special variable-frequency motor, in solution prior art, the body of the special variable-frequency motor of water pump is comparatively large, integrated level is low and the defect that reliability is poor, realize the overall volume reducing the special variable-frequency motor of water pump, improve integrated level and the reliability of the special variable-frequency motor of water pump.
The technical scheme that the utility model provides is, the special variable-frequency motor of a kind of water pump, comprise shell, stator, rotor and frequency conversion control circuit, described rotor has motor shaft, described shell is provided with end cap, be exposed at the outside of described end cap outside the output of described motor shaft, described end cap is formed with semiclosed cavity structure, described frequency conversion control circuit is arranged in described semiclosed cavity structure.
Further, described end cap is also provided with fin, described fin and described semiclosed cavity structure form hermetically-sealed construction.
Further, the outer surface of described fin is also provided with multiple radiation tooth.
Further, the output of described motor shaft is also provided with centrifugal fan, and described centrifugal fan is positioned at the side of described fin.
Further, form groove between multiple described radiation tooth, described centrifugal fan is arranged in described groove.
Further, described frequency conversion control circuit is fixed on described fin.
Further, described end cap is provided with the first through wires hole, described shell is provided with terminal box, described terminal box is provided with the second through wires hole, described first through wires hole is connected with described second through wires hole by wire barrel.
Further, also comprise terminal pad and pump seat, described pump seat is fixed on described end cap by described terminal pad.
Compared with prior art, advantage of the present utility model and good effect are: the special variable-frequency motor of the water pump that the utility model provides, by first enclosed cavity structure of end cap of the shell at motor, frequency conversion control circuit can be corresponding be arranged on semiclosed cavity structure, semiclosed cavity structure is on the one hand for being assembled in shell by integrated for frequency conversion control circuit, semiclosed cavity structure is also for distributing the heat that frequency conversion control circuit produces on the other hand, to meet the cooling requirements of frequency conversion control circuit, and frequency conversion control circuit is integrated in shell, the portion in the enclosure that realizes completes wiring and connects, and do not need the wiring of carrying out in the outside of shell, in use procedure, fault point is less, improve the reliability of the special variable-frequency motor of water pump, in addition, because motor shaft is through semiclosed cavity structure, semiclosed cavity structure by make full use of motor shaft overhanging go out the space of shell to install the parts such as frequency conversion control circuit, such that the overall volume of the special variable-frequency motor of water pump is compacter, integrated level is higher, effectively reduce the overall volume of the special variable-frequency motor of water pump.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
