Abstract
The invention relates to the technical field of variable frequency motors, in particular to an installation structure of a variable frequency motor fan. The installation structure of the variable frequency motor fan comprises a main motor and a fan, and is characterized in that a motor outlet box and a motor rear end cover are arranged on the main motor, and a fan motor, a fan cover and a fan blade are arranged on the fan; a small flange is arranged at the front end of the fan motor and is fixed on the motor rear end cover through screws; a transition sleeve is arranged at the shaft extension end of the rear end of the fan motor, and the fan blade is connected with the shaft extension end of the fan motor through the transition sleeve; the outgoing line of the fan motor is arranged in the motor outlet box; and the fan cover is arranged at the outer part of the motor fan. The installation structure of the variable frequency motor fan has the advantages of reasonable design, simple structure, stable operation and convenience in wiring. The fan motor and the fan cover are completely separated, and the transition sleeve is arranged at the shaft extension end of the fan motor, so that shape of the fan blade and the fan cover of the variable frequency motor can be optionally selected.
Description
Technical field
The present invention relates to the technical field of variable-frequency motor blower fan, specifically a kind of mounting structure of variable-frequency motor blower motor.
Background technology
The at present application of control motor is more and more extensive, and take variable-frequency motor as main, its application is more more extensive in the control motor, therefore the performance requirement of variable-frequency motor, degree easy to use and flexible design degree has all been proposed very high requirement.Present variable-frequency motor blower fan is partly made as a whole standard component and is designed by blower fan manufacturer, its blower motor is installed on the fan housing, as a whole with the fan housing assembling, its design is difficult to satisfy the wind path demand of all motors, brings significant limitation for the design of variable-frequency motor.Be subjected to the impact of its structure, motor manufacturer can only carry out according to blower fan the design of motor and blower fan fitted position, the fan housing with blower motor is fixed on motor rear end covers.Because blower motor is heavier, whole weight all is added on the fan housing, is fixed on motor rear end by fan housing again and covers, and causes the fan housing distortion, and it is very large to produce simultaneously the vibrations noise in the operation process.
Summary of the invention
The objective of the invention is in order to solve the deficiency of above-mentioned technology, provide a kind of reasonable in design, simple in structure, operate steadily, wiring is convenient, blower motor separates fully with fan housing, can choose at random variable-frequency motor fan blade, fan housing form, break the place one's entire reliance upon situation of blower fan factory of variable-frequency motor fan blade.
The technical solution adopted in the present invention is: a kind of mounting structure of variable-frequency motor blower fan, comprise main motor, blower fan, it is characterized in that main motor is provided with motor wire outlet box, back end cover for motor, blower fan is provided with blower motor, fan housing, fan blade, be provided with little flange at the blower motor front end, by screw little flange being fixed on motor rear end covers, the shaft extension end of blower motor rear end is provided with spacer shell, fan blade is connected with the blower motor shaft extension by spacer shell, the outlet of blower motor is located in the motor wire outlet box, and the motor fan outside is provided with fan housing.
Because the little flange of blower motor front end is fixed by screws in main motor rear end and covers, and is integral with main electrical mechanisms, its blower motor outlet and motor outlet wire are incorporated in the motor wire outlet box, make motor easy to manufacture, and be easy to use.Fan housing separates with blower motor, increased the selectivity of fan blade and fan housing, can select suitable fan blade, fan housing according to different demand, the fan housing weight that need not bear blower motor simultaneously makes the vibrations reducing noise of fan housing in the whole variable-frequency motor operation process.
The present invention is reasonable in design, simple in structure, and is easy to manufacture, operates steadily, wiring is convenient, and blower motor separates fully with fan housing, can choose at random the structure of variable-frequency motor fan blade, fan housing.
Description of drawings
