Abstract
The utility model relates to an electric motor postfix converter p device. The utility model comprises a radiator fan, a radiator, a frequency conversion circuit board, a shielding protection cover and a regulate box. The radiator fan is directly arranged on the back cover of the electric motor. The shielding protection cover is fixed on the back end of the electric motor. The cylindrical radiator is fixed on the lateral side of the shielding protection cover. The frequency conversion and the components are fixed inside the radiator. The utility model has the advantages of compact structure, volume be greatly reduced, saving materials and convenient for maintaining. The utility model arranges the fan on the back cover of the electric motor, which can maximally reduce the problem that the support intensity of the variable-frequency governor is not enough because of the vibration of the fan.
Description
Technical field
The utility model relates to a kind of variable-frequency governor that is installed in the motor.
Background technology
It is big that the motor frequency change speed regulator can solve the alternating current motor starting current, the low and rotating speed adjustment enforcement complicated problems of detent torque.This variable-frequency governor can be implemented multi parameters control to frequency changer circuit with single chip microcomputer, makes motor realize stepless speed regulation and the output of multiple mechanical property.This device can also be implemented closed-loop control by transducer with matched host machine.Above-mentioned motor and frequency converter generally are under the split situation, are provided with separately separately, cause device to install and use more complicated thus, and shortcomings such as big and complex structure take up room.
Summary of the invention
The rear-mounted converter plant of a kind of motor described in the utility model can solve the problem that motor and frequency-variable electronic device are combined into one.
The rear-mounted converter plant of a kind of motor described in the utility model comprises radiator fan, radiator, frequency changer circuit plate, shielding protection cover and regulation and control box; Wherein radiator fan directly is fixed on the rear end cap of motor by trip bolt; In shielding protection cover lower end, the fan guard fixing screw hole place on the corresponding former motor rear end plate has corresponding screw hole, and is fixed in the motor rear end by screw; Described radiator is a cylindrical shape, and outer surface is evenly equipped with the radiation radiating ribs, is mounted with frequency changer circuit components and parts and wiring board in the radiator inner space, has a cover plate to be positioned at the infraoral of radiator; Described radiator directly is fixed on the shielding protection cover by screw, and is positioned at the radiator fan outside; Space between shielding protection cover and the radiator forms the air intake passage of motor.
The rear-mounted converter plant of aforesaid a kind of motor, wherein a side of radiator has a port that extends out to the shielding protection cover outside, the regulation and control box of frequency converter is installed in the port outer end, the line of regulation and control box is introduced in the radiator by this port, this regulation and control box can dock with the terminal box on the former motor, forms and controls plate.
The rear-mounted converter plant of a kind of motor described in the utility model is compared with traditional split type electric motor frequency converter, has following good effect and advantage:
1. because electromechanical integration makes conventional variable-frequency governor combine with motor, so compact conformation, volume and occupation of land usable floor area dwindle greatly;
2. reduce the parts that main frame and frequency converter repeat to be provided with in the architomia device, reduced the supporting cost of main frame;
3. reduce the influence of fan vibrations to greatest extent to variable-frequency governor;
4. the not enough problem of having avoided cooling fan to be directly installed on causing on the frequency-variable electronic device of support strength.

Embodiment
The utility model concrete structure can be referring to accompanying drawing.Among Fig. 1, on the rear end cap 5 of motor 1, fan 10 is installed by screw 9.Shielding protection cover 8 lower ends, the fan guard fixing screw hole place on the corresponding former motor rear end plate 5 has corresponding screw, and by screw 14 that they are fastening.On shielding protection cover 8 tops, be fixed with one by screw 13 and place shielding protection cover 8 inboards, and be positioned at the barrel radiator 7 in radiator fan 10 outsides.Between radiator 7 inner chambers and infraoral cover plate 6, be fixed with the components and parts and the wiring board 12 of frequency converter.Radiator 7 sides are mounted with frequency conversion switching device 11.In a side of radiator 7, extending outwardly into the shielding protection cover outside has a port, and this port outer end is fixed with the regulation and control box 4 of frequency converter, and described regulation and control box 4 docks with the terminal box 2 on the former motor to form controls plate 3.The circuit connection of described regulation and control box 4, the port of stretching by an epitaxial lateral overgrowth of radiator 7 are introduced on the frequency conversion wiring board in the radiator.
Fig. 2 is the elevation cross-sectional view of barrel radiator, and its top has and is used for and the shielding protection cover fixing screw hole.Fig. 3 is the vertical view of barrel radiator, and the barrel radiator top portion is furnished with radial heat dissipation plate as can be seen from Figure, and this heat dissipation plate extends to the periphery of radiator always.
This device is installed a cooling fan between motor and frequency-variable electronic speed regulator, cold wind sucks from the air channel that forms between the barrel radiator of frequency-variable electronic speed regulator and the shielding protection cover, to the cooling of frequency-variable electronic speed regulator, also motor is cooled off simultaneously.
