The utility model discloses a set up wind wheel heat dissipation with higher speed between front end housing and rotor, not only improved three -phase alternating current machine's heat dispersion, but also reduced the vibration that produces when three -phase alternating current machine starts.
Description
Technical field
The utility model relates to machine field, particularly a kind of three phase alternating current motor.
Background technology
Three phase alternating current motor refers to the threephase stator winding (each difference 120 degree of electrical degrees) when motor, after passing into three-phase alternating current, by generation rotating magnetic field, this rotating magnetic field cutting rotor winding, thus in rotor windings, produce induced current (rotor windings is close access), the rotor conductor of current-carrying will produce electromagnetic force under the effect of stator rotating magnetic field, thus electromagnetic torque is formed on machine shaft, drive motor rotates, and motor direction of rotation is identical with rotating magnetic field direction.
The heat dispersion of three phase alternating current motor is the important indicator weighing its quality.At present, in order to improve the heat dispersion of three phase alternating current motor, way general is in the industry: outside the rear end cap of three phase alternating current motor, install one additional for accelerating the wind wheel of air circulation.But, outside the rear end cap of three phase alternating current motor, install the way of wind wheel additional, not only improve limited to the heat dispersion of three phase alternating current motor, and the vibration produced when starting obviously can increase.And vibration during three phase alternating current motor startup is also the important factor affecting motor performance.Obviously, the vibration produced during startup is less, then performance is better.Therefore, exploitation one had both had good heat dispersion, and the three phase alternating current motor that the vibration of generation during startup is little is again necessary very much.
Utility model content
The purpose of this utility model is, provides a kind of three phase alternating current motor.This three phase alternating current motor not only has heat dispersion more better than existing three phase alternating current motor, and when starting, its vibration produced is also less.
The technical solution of the utility model: three phase alternating current motor, comprise casing, the both sides of casing are respectively equipped with front end housing, the rear end cap of band gas channel, and the inside of casing is provided with mutually corresponding stator, rotor and rotating shaft, and the interior sidewall surface of described front end housing is provided with A roughing efficiency air filter; The outer side surface of described rear end cap is provided with B roughing efficiency air filter, and the inner webs face of described rear end cap is provided with high efficiency particulate air filter; In described rotating shaft, between front end housing and rotor, be provided with the wind wheel for accelerating air circulation.
In aforesaid three phase alternating current motor, described A roughing efficiency air filter and B roughing efficiency air filter are nylon filter; Described high efficiency particulate air filter is the efficient filter screen of V-BED.
In aforesaid three phase alternating current motor, described wind wheel has 10 with blade.
As preferably, in aforesaid three phase alternating current motor, described wind wheel has 10 blades.
In aforesaid three phase alternating current motor, the material of described wind wheel is aluminium alloy.
Compared with prior art, the utility model, by arranging wind wheel between front end housing and rotor, accelerates heat radiation, not only increases the heat dispersion of three phase alternating current motor, but also reduces the vibration produced when three phase alternating current motor starts; The filter be arranged on front and rear cover sidewall can prevent the dust particle in air, particle dust enters motor internal, causes damage to motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-casing, 2-front end housing, 3-rear end cap, 4-stator, 5-rotor, 6-rotating shaft, 7-A roughing efficiency air filter, 8-B roughing efficiency air filter, 9-high efficiency particulate air filter, 10-wind wheel.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.Three phase alternating current motor, forms as shown in Figure 1, comprises casing 1, and the both sides of casing 1 are respectively equipped with front end housing 2, the rear end cap 3 of band gas channel, and the inside of casing 1 is provided with mutually corresponding stator 4, rotor 5 and rotating shaft 6.Be characterized in: the interior sidewall surface of described front end housing 2 is provided with A roughing efficiency air filter 7; The outer side surface of described rear end cap 3 is provided with B roughing efficiency air filter 8, and the inner webs face of described rear end cap 3 is provided with high efficiency particulate air filter 9; In described rotating shaft 6, between front end housing 2 and rotor 5, be provided with the wind wheel 10 (wind wheel 10 is made up of wheel hub and the blade be arranged on wheel hub) for accelerating air circulation.
Described A roughing efficiency air filter 7 and B roughing efficiency air filter 8 are nylon filter; Described high efficiency particulate air filter 9 is the efficient filter screen of V-BED (V-type Wind Volume high efficiency particulate air filters).
Described wind wheel 10 has 10 with blade.As preferably, described wind wheel 10 has 10 blades.The material of described wind wheel 10 is aluminium alloy.
Below to related description of the present utility model:
A roughing efficiency air filter 7 is mainly used in preventing the dust particle in air (particle diameter is more than 5 μm) from falling into motor internal, causes damage to motor.B roughing efficiency air filter 8 tentatively filters the air being about to enter casing 1 inside, removes dust particle, alleviate the burden of high efficiency particulate air filter 9, make high efficiency particulate air filter 9 have longer useful life.High efficiency particulate air filter 9 is mainly used in filtering particle dust (particle diameter is 0.5 μm ~ 5 μm), prevents particle dust to be inhaled into motor internal, causes damage to motor.
During machine operation, wind wheel 10 rotates with rotating shaft 6, constantly the gas channel of the hot-air of casing 1 inside on front end housing 2 is discharged, make the air pressure of casing 1 inside lower than external pressure, like this, outside cold air will constantly pour in casing 1 inside by the gas channel on rear end cap 3, accelerates air circulation, reaches heat radiation object.Research finds, is arranged on by wind wheel 10 between front end housing 2 and rotor 5, not only good heat dissipation effect, and the vibration produced when can reduce to start; When wind wheel 10 have 10 with blade time, effect is better, and when especially having 10 blades, performance reaches best, causes vibration hardly.In addition, experiment shows, during the material selection aluminium alloy of wind wheel 10, its longer when ratio selects PVC, carbon steel in useful life.
