Abstract
The purpose of this utility model is to provide a kind of variable-frequency motor, the cooling effect of controller can be improved and reduce the volume of motor assembly, including motor body and for arranging the controller box body of control circuit Slab element, blower fan is provided with the rear end cap of motor body, controller box body is arranged between rear end cap and blower fan.In such scheme, controller box body is arranged between rear end cap and blower fan, controller can also be cooled down while blower fan cools down to motor body, it is not necessary to separately controller is cooled down with a set of cooling system, the energy is saved, and reduces the overall volume of variable-frequency motor.
Description
Technical field
It the utility model is related to technical field of motors, and in particular to a kind of structure of variable-frequency motor is improved.
Background technology
Widely used frequency conversion control technique carrys out the work of controlled motor in the prior art, with improve the operating mode of motor operation and
Have the advantages that to improve energy-saving effect.Controller box of the prior art is mounted in connection box for motor, because motor has
Cooling fan is air-cooled to motor body implementation to ensure the reliability of motor operation, and controller box is then without corresponding cooling hand
Section, therefore the service life of controller is had a strong impact on, set up the cooling systems such as cooling fan in addition if electric machine controller, this
Sample is difficult to ensure that the miniaturization of motor volume or the cost of motor dramatically increase.
Utility model content
The purpose of this utility model is to provide a kind of variable-frequency motor, can improve the cooling effect of controller and reduce motor
The volume of assembly.
To achieve these goals, the technical solution adopted in the utility model is：A kind of variable-frequency motor, including motor body
With the controller box body for arranging control circuit Slab element, blower fan, controller box body are provided with the rear end cap of motor body
It is arranged between rear end cap and blower fan.
In such scheme, controller box body is arranged between rear end cap and blower fan, motor body carried out in blower fan cold
But controller can also be cooled down while, it is not necessary to separately controller is cooled down with a set of cooling system, saves energy
Source, and reduce the overall volume of variable-frequency motor.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
As shown in figure 1, a kind of variable-frequency motor, including motor body 10 and the controller for arranging control circuit Slab element
Box body 20, blower fan 30 is provided with the rear end cap 11 of motor body 10, controller box body 20 is arranged on rear end cap 11 and blower fan 30
Between.Controller box body 20 is arranged between rear end cap 11 and blower fan 30, motor body 10 cooled down in blower fan 30
Controller can also be cooled down simultaneously, it is not necessary to separately controller is cooled down with a set of cooling system, saves the energy, and
Reduce the overall volume of variable-frequency motor.
Further, described controller box body 20 is fixedly connected with rear end cap 11 by screw, rear end cap 11 and control
The junction of the box chamber of device box body 20 offers fairlead a, and controller box body 20 is disposed with batten in the outer plate surface of blower fan 30
The fin 21 of shape, and the board direction of fin 21 is consistent with the axial direction of motor body 10.Drawing on motor body 10
Line is entered by fairlead a controller box body 20 and to be connected with the control circuit Slab element in box, by controller box body 20 directly with
Rear end cap 11 connects, and can reduce the overall volume of variable-frequency motor, the direction of the plate face of fin 21 contributes to blower fan 30
The circulation of air-flow.
Motor body 10 is cooled down in order to facilitate air-flow, the junction of rear end cap 11 and support is provided with distinguished and admirable path,
The silver 12 that radiates is also equipped with the outer peripheral face of support, radiate the length direction of silver 12 and the axial direction one of motor body 10
Cause.The direction of the length of radiating silver 12 contributes to the circulation of the air-flow of blower fan 30.
Further, blower fan 30 and the peripheral closure of controller box body 20 are provided with fan shroud 40, and fan shroud 40 is cylindrical in shape and blower fan
One end of cover 40 is bolted to connection with support.
Because rear end cap 11 will be connected with controller box body 20, described blower fan 30 is external fan.
