Abstract
The invention discloses a motor with self-cooling fans. The motor comprises a cooler, a stator, self-cooling fan systems and a rotor, wherein the cooler is mounted at the back of the stator. The motor is characterized in that the self-cooling fan systems are arranged in spaces at the end parts of the rotor and the stator, and the rotor supplies power for the self-cooling fan systems. According to the motor, the self-cooling fan systems are arranged at the end parts of the rotor and the stator; the fan and the motor are not required to be mounted on the cooler; noises generated by the fan can be obstructed by a motor end cover and a housing; and the noises transmitted to an external environment are very low, so that the noises of the whole motor is reduced. Particularly, the fans are high in rotating speed due to increasing of gear groups, the high air pressure can be generated, and the sufficient air quantity can be provided for a cooling air path.
Description
Technical field
The present invention relates to technical field of motors, relate in particular to a kind of motor with self-cooling fan.
Background technology
High-power, the application of Low speed electric motor in modern industry is increasing, as steel mill electric machine, slow-speed of revolution magneto etc., this class motor is generally installed cooler at the motor back and is cooled off.In order to improve cooling effect, generally all be at cooler a plurality of fans to be installed to provide blast for cooling air duct, the motor of fan is powered by external three-phase alternating-current supply.But these fan electromotors are directly exposed in the environment, and its noise is very big, even have surpassed the noise of motor body, and the working site workers'health is produced greatly influence.
Summary of the invention
The objective of the invention is provides the motor of the built-in band self-cooling fan of a kind of fan in order to overcome above defective.
Technical scheme of the present invention is: a kind of motor with self-cooling fan, and it comprises cooler, stator, the self-cooling fan system, rotor, cooler is installed in stator back, described self-cooling fan system places the space of rotor and stator end, and the power source of self-cooling fan system is provided by rotor.
In order to improve cooling effect, described self-cooling fan system places in two end spaces of rotor and stator.
In order to adapt to slowspeed machine, also comprise speeder, the power shaft of described speeder is armature spindle, described fan is located on the output shaft of speeder.
Described speeder comprises gear wheel, pinion, output shaft, bracing frame, gear wheel is located on the armature spindle, bracing frame and stator are fixed together, output shaft by bearing fixing on bracing frame, one end of output shaft is provided with pinion, and the other end of output shaft is provided with fan, and gear wheel and pinion are combined into the speed increasing gear group together.
Technique effect of the present invention is, the self-cooling fan system is placed rotor and stator end, avoided at cooler fan and motor being installed, fan produces noise to be stopped by electric motor end cap and shell, it is very low to pass to external environment noise, and then has reduced the noise of whole motor.Particularly make fan that high rotational speed be arranged by the speed increasing gear group, can produce bigger blast, for cooling air duct provides enough air quantity.

Fig. 1 is electric machine structure and the ventilation diagram of the embodiment of the invention;
Fig. 2 is the self-cooling fan system configuration schematic diagram of the embodiment of the invention.
Embodiment
The present invention is described in more detail below in conjunction with drawings and Examples.
With reference to accompanying drawing, a kind of motor with self-cooling fan, it comprises cooler 1, stator 2, self-cooling fan system 3, rotor 4.Cooler 1 is installed in stator 2 backs, and self-cooling fan system 3 places in the end space of rotor 4 and stator 2.Self-cooling fan system 3 comprises fan 10 and speeder 11, wherein speeder 11 comprises gear wheel 5, pinion 6, output shaft 7, bracing frame 9, gear wheel 5 is located on the axle of rotor 4, bracing frame 9 is fixed together with stator 2, and output shaft 7 is fixed on the bracing frame 9 by bearing 8, and an end of output shaft 7 is provided with pinion 6, the other end of output shaft 7 is provided with fan 10, and gear wheel 5 and little tooth 6 are taken turns to mesh together and be combined into the speed increasing gear group.
During the motor operation, slow-revving rotor 4 drives gear wheel 5 and rotates, because gear train has certain speed ratio, makes pinion 6 rotating speeds higher, and then drives fan 10, makes it that high rotational speed be arranged, and produces bigger blast, provides cooling system enough air quantity.Self-cooling fan system 3 is placed the end of rotor 4 and stator 2, avoided at cooler 1 fan and motor being installed, the noise that fan 10 produces is stopped that by electric motor end cap and shell it is very low to pass to external environment noise, and then has reduced the noise of whole motor.Particularly make fan 10 that high rotational speed be arranged by the speed increasing gear group, can produce bigger blast, for cooling air duct provides enough air quantity.
More than be a kind of execution mode of invention, a preferred demonstration example.The scope that the present patent application is asked for protection has more than and is limited to described execution mode.The technical scheme of all and present embodiment equivalence adopts belt or chain drive as speeder, and it all belongs to protection scope of the present invention.
