Abstract
The utility model discloses a high-efficiency air cooling variable frequency motor. The variable frequency motor comprises a variable frequency motor body provided with a spindle, blades arranged on the right end of the body, a drive device connected with the blades, and a protection cover arranged outside the blades, wherein the protection cover is provided with an air inlet and an air outlet; the left end of the protection cover extends to the left part of the body; a slit is formed between the protection cover and the body; the air inlet is located on the right end of the protection cover; and the air outlet is formed on the left part of the protection cover. After optimization, a horizontal stiffener is arranged between the protection cover and the body. The high-efficiency air cooling variable frequency motor provided by the utility model has the advantages that the blades have high utilization rate of the blades, and the variable frequency motor has uniform cooling rate.
Description
Technical field
The present invention relates to technical field of motors, especially relate to a kind of high-efficiency air cooling variable-frequency motor.
Background technology
Along with the extensive use of frequency converter in industrial control field, the use of variable-frequency motor is increasingly extensive, and reason is that variable-frequency motor has larger superiority than common electric machine aspect variable frequency control.But variable-frequency motor has higher requirements to working temperature.General, the type of cooling that variable-frequency motor adopts is that the tail end of variable-frequency motor is provided with fan blade, fan blade is connected with power set.Wherein, power set can be ventilated machines independently, also can be main shafts.Like this, the fan blade High Rotation Speed carries out forced air cooling to variable-frequency motor.Its defective is: fan blade is positioned at the tail end of variable-frequency motor, thereby only the tail end of this variable-frequency motor is cooled off, and causes the fan blade cooling effectiveness lower, and the variable-frequency motor cooling is uneven.Therefore be necessary to be improved.
Summary of the invention
Deficiency for above-mentioned prior art exists the purpose of this invention is to provide a kind of high-efficiency air cooling variable-frequency motor, and it is higher that it has the fan blade utilance, the characteristics of variable-frequency motor lowering temperature uniform.
To achieve these goals, the technical solution adopted in the present invention is: the high-efficiency air cooling variable-frequency motor, comprise the variable-frequency motor body, body is provided with main shaft, and the right-hand member of body is provided with fan blade, this fan blade is connected to power set and the outside is provided with guard shield, guard shield is provided with air inlet and air outlet, and the left end of described guard shield extends to the left part of body, and is provided with the slit between guard shield and the body, air inlet is positioned at the right-hand member of guard shield, and air outlet is positioned at the left part of guard shield.
Be provided with vertical gusset between described guard shield and the body.
Described vertical gusset is 6 ~ 10, and evenly distributes along the outer surface of body.
After adopting said structure, the present invention is compared with existing technology the advantage that has and is: the fan blade utilance is high, the variable-frequency motor lowering temperature uniform.The front end of the fan blade guard shield of high-efficiency air cooling variable-frequency motor of the present invention extends to the front portion of variable-frequency motor body, and air outlet is positioned at the front portion of guard shield.Like this, after the fan blade rotation, cold wind is close to body and is delivered to the front portion of body from the rear portion of body, thereby the time of contact of cold wind and body is long, and contact area is large, makes the heat exchanger effectiveness between cold wind and the body high, and most of positions of body have all obtained cooling.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is that the master of embodiments of the invention looks cutaway view;
Fig. 2 is the left view of Fig. 1.
Among the figure: 10, body, 11, main shaft; 20, fan blade; 30, guard shield, 31, air inlet, 32, air outlet, 33, vertical gusset.
Embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see illustrated in figures 1 and 2: the high-efficiency air cooling variable-frequency motor comprises variable-frequency motor body 10.Body 10 is provided with main shaft 11, and main shaft 11 is used for output torque.The right-hand member of body 10 is provided with fan blade 20, and this fan blade 20 is connected to power set.Power set can be main shafts 11, also can be ventilated machines independently.The outside of fan blade 20 is provided with guard shield 30, and guard shield 30 is provided with air inlet 31 and air outlet 32, and the left end of guard shield 30 extends to the left part of body 10.Simultaneously, be provided with the slit between guard shield 30 and the body 10.At this moment, air inlet 31 is positioned at the right-hand member of guard shield 30, and air outlet 32 is positioned at the left part of guard shield 30.Obviously, air outlet 32 can be formed by the slit between guard shield 30 and the body 10, also can be positioned on the left part side of guard shield 30.Like this, after fan blade 20 rotations, cold wind is close to body 10, passes the slit between guard shield 30 and body 10, and body 10 has been carried out comparatively comprehensively cooling.
Optimize, be provided with vertical gusset 33 between guard shield 30 and the body 10.Like this, not only can support guard shield 30, and can guide cold wind.This vertical gusset 33 can be 6 ~ 10, and evenly distributes along the outer surface of body 10.
