Description
Technical field
The utility model relates to the rear-mounted variable-frequency governor of a kind of 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 one 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 Unit Installation thus and use more complicated, and shortcomings such as big and complex structure take up room.
Summary of the invention
The rear-mounted variable-frequency governor 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 variable-frequency governor of a kind of motor described in the utility model, it comprises: the circuit board of frequency converter, radiator, regulation and control box, fan and shielding protection cover; Radiator wherein is patty or drum shape, and the patty radiator fixes by tubular cover plate and the motor rear end plate that periphery is screwed, and described drum shape radiator can be directly fixed on the motor rear end plate; Described radiator inner space is fixed with the circuit board and the electronic devices and components of variable-frequency governor; By the fan guard fixing screw hole on the former motor rear end plate, described shielding protection cover is fixed on the motor rear end with screw; The fastened screw of described fan forms the air blast heat dissipation wind channel in described radiator upper end between shielding protection cover and the radiator.
The rear-mounted variable-frequency governor of aforesaid a kind of motor is installed in the frequency conversion switching device on the described radiator.
The rear-mounted variable-frequency governor of aforesaid a kind of motor stretches out one and connects neck on the outer circumference of shielding protection cover, in order to install and fix the regulation and control box, described regulation and control box docks with former motor JB, forms to control plate.
The rear-mounted variable-frequency governor of a kind of motor described in the utility model is compared with traditional detachable electric machine frequency converter, has following good effect and advantage:
1. because electromechanical makes conventional variable-frequency governor combine with motor, so compact conformation, volume and occupation of land usable floor area dwindle greatly;
2. reduced the parts that main frame and frequency converter repeat to be provided with in the architomia device, reduced the supporting cost of main frame and saved material;
3. the RHVC overall performance is good, and is easy to maintenance.

Embodiment
The rear-mounted variable-frequency governor of a kind of motor described in the utility model, be the fan guard of removing former alternating current motor 1 back and with the coaxial cooling fan of motor after, be installed on the motor rear end plate place, the electromechanical structure of formation.A reflection embodiment of the present utility model among Fig. 1, wherein the periphery of patty radiator 7 has a cylindrical shape cover plate 6 by screw, and these cylindrical shape cover plate 6 other ends are fixed on by screw 14 on the periphery of rear end cap 5 of former motor.Shielding protection cover 8 is installed in former electrical motor fan place, and utilizes the fan fixing threaded hole 13 of motor rear end plate 5 to fix.Described radiator fan 10 directly is fixed on the upper top central authorities of radiator 7 by trip bolt 9.Described frequency conversion switching device 11 is installed in a side of radiator 7.The periphery of described shielding protection cover 8 stretches out one and connects neck near motor connecting cartridge 2 places, and in order to install and fix regulation and control box 4, described regulation and control box 4 docks with terminal box 2, forms to control plate 3.In an inner space of patty radiator 7 and 6 formation of cylindrical shape cover plate, the circuit board 12 of variable-frequency governor and other electronic devices and components are installed.Form the air channel at above-mentioned shielding protection cover 8 gap locations inboard and the converter plant outside, can make fan 10 that cold wind is blowed to motor by this air channel, for motor provides cooling air, shielding protection cover 8 can also prevent the interference of external electromagnetic waves to this device, also prevents that the electromagnetic wave that this device self forms from externally disturbing simultaneously.Shielding protection cover 8 can prevent that external force is to the destruction of converter plant and fan is played the security protection effect.
What Fig. 2 reflected is the enforcement illustration of barrel radiator.Wherein radiator is a cylindrical shape, can establish a cover plate at the barrel radiator infraoral, and 15 described barrel radiators can be directly fixed on the motor rear end plate 5, and place and the fixedly circuit board and the electronic devices and components of variable-frequency governor its inner space.Other structure is with shown in Figure 1.
Fig. 3,4 is the front view and the cutaway view of patty radiator.In the front of radiator, promptly the radiator outer wall is uniformly distributed with heat dissipation plate.Heat dissipation plate makes cooling air more even, motor cooling better effects if.
Fig. 5,6 is the front view and the cutaway view of barrel radiator.Outer wall at radiator is uniformly distributed with heat dissipation plate.
Above-mentioned patty radiator is applicable to power and the less miniature motor of installing space.Barrel radiator is applicable to that then motor power (output) and frequency conversion switching device requirement area of dissipation are bigger, and on the also bigger high capacity motor of installing space.
