The defects of body of the special variable-frequency motor of pump is larger, integrated level is low and reliability is poor, realizes and reduce the special variable-frequency motor of water pump
Overall volume, improve the integrated level and reliability of the special variable-frequency motor of water pump.
Technical scheme provided by the invention is a kind of special variable-frequency motor of water pump, including shell, stator, rotor and frequency conversion
Control circuit, the rotor have motor shaft, and the shell is provided with end cap, and the output end of the motor shaft is exposed at the end
The outside of lid, it is located at the semiclosed cavity knot formed with semiclosed cavity structure, the frequency conversion control circuit on the end cap
In structure.
Further, fin is additionally provided with the end cap, the fin is formed with the semiclosed cavity structure
Sealing structure.
Further, the outer surface of the fin is additionally provided with multiple radiation tooths.
Further, the output end of the motor shaft is additionally provided with centrifugal fan, and the centrifugal fan is positioned at described
The side of fin.
Further, groove is formed between multiple radiation tooths, the centrifugal fan is located in the groove.
Further, the frequency conversion control circuit is fixed on the fin.
Further, the first threading hole is provided with the end cap, terminal box, the terminal box are provided with the shell
On be provided with the second threading hole, first threading hole is connected by wire barrel with second threading hole.
Further, in addition to terminal pad and pump seat, the pump seat are fixed on the end cap by the terminal pad.
Compared with prior art, the advantages and positive effects of the present invention are：The special variable-frequency motor of water pump provided by the invention,
By the end cap upper half closed cavity structure of the shell in motor, frequency conversion control circuit corresponding can be arranged on semiclosed cavity
On the one hand structure, semiclosed cavity structure are used to integrate frequency conversion control circuit to be assembled in shell, on the other hand semiclosed sky
Cavity configuration is additionally operable to distribute heat caused by frequency conversion control circuit, to meet the cooling requirements of frequency conversion control circuit, and frequency conversion control
Circuit processed is integrated in shell, is realized and is completed wiring connection inside the housing, without the carry out wiring in the outside of shell,
During use, trouble point is less, improves the reliability of the special variable-frequency motor of water pump；Further, since motor shaft seals through half
Close cavity structure, semiclosed cavity structure will make full use of motor shaft to overhang the space of shell to install frequency conversion control circuit etc.
Part so that the overall volume of the special variable-frequency motor of water pump is compacter, integrated level is higher, the special change that effectively reduces water pump
The overall volume of frequency motor.
