Description

There is the motor of heat abstractor
Technical field
The utility model belongs to office appliances technical field, particularly relates to a kind of motor with heat abstractor for shredder.
Background technology
The transliteration of motor: motor is motor, motor, and it is a kind of equipment that converts electrical energy into mechanical energy according to the law of electromagnetic induction, for various device provides power source.Because motor running is via due to electromagnetism dissection, because the effect of current resistor will produce heat, electric current is larger, and the heat of generation is also just more, the rotor of motor is made up of some coiling groups, in the time of motor operations, the heat that electric current produces by the coiling group of rotor is maximum, if stator is also made up of coiling group, in the time of motor operations, also larger heat will be produced, because stator and shell are that the heat directly contacting is conducted very fast, and then make the temperature of shell higher, and between rotor and the shell of motor by air transmitted heat, make between rotor and the shell of motor the coefficient of heat conduction low, heat conduction velocity is slow, and again because the temperature of the effect shell of stator is higher, and then cause heat to be contained in shell inner accumulated, thereby affect the combination property of motor, reduce the efficiency of motor operation, increase the energy consumption of motor, and then the operating cost of increase motor, even there is the situation that motor burns.
At present; existing shredder because of its service condition be intermittence shredded paper; comparatively tight in the use in product design medium power source; like this having while using slightly for a long time; the temperature raising speed of motor is too fast; make the machine situation that often occurs overheat protector in service, cause can only break-off or long-term standby cooling after the phenomenon of working again.For solving the phenomenon of above-mentioned existence, existing publication number is CN 202142951 U, name is called a kind of the have motor of air-cooled radiating device and the Chinese patent of shredder, disclosed technical scheme is to install in addition aerofoil fan additional at motor shaft tail end to dispel the heat, although being motor in motor operations and when motor stops, it does to lower the temperature, radiating efficiency is also relatively better, but because aerofoil fan is from translator, power supply need to be provided in addition, energy consumption is relatively just higher, and motor front end need to arrange air inlet, making needs to reserve an intersegmental distance between motor front end and fixed support, in the time of motor operations, the stress that the anterior output shaft of motor is subject to is relatively concentrated, also easily cause in the output shaft segment set of heat between motor front end and fixed support, and in actual use, if motor front end periphery wall is provided with individual air inlet, but this air inlet is poor to the concentration effect of wind, cause near the radiating effect of the output shaft of air inlet relatively poor, once the heat of this part output shaft leaves not in time, easily cause this part output shaft answer torsion and be out of shape, significantly shorten the useful life of output shaft.
Publication number is CN 202142951 U, name is called and a kind ofly has the motor of air-cooled radiating device and the Chinese patent of shredder also discloses in background technology that " another kind of motor heat sink is to set up fan in the end of motor output shaft; due to the high speed continuous running of motor output shaft; easily come off from motor output shaft because lasting vibration causes fan, cause mechanical disorder." the utility model can overcome above-mentioned defect.
Utility model content
The utility model provides a kind of energy consumption relatively low for above problem, and output shaft is had to good radiating effect, does not affect output shaft normal service life and stability in use and have preferably the motor of heat abstractor.
The utility model overcomes the above problems technical scheme used: a kind of motor with heat abstractor with following structure is provided, it comprises motor shell and is rotatably connected on the motor rotor in motor shell, described motor rotor is divided into rotor coil and output shaft, the two ends of described motor shell are respectively equipped with rear end cap and front end housing, the position of the described nearly rear end cap of motor shell outer peripheral face is provided with several air inlets, and air inlet is communicated with motor shell inner chamber, between described motor shell and front end housing, be provided with air blast, described air blast comprises air blast shell and flabellum, fan blade rotating is automatically connected in air blast shell, the import of described air blast shell is communicated with motor shell inner chamber, described flabellum is connected on output shaft.
Adopt after above structure, compared with prior art, the utility model is because the position of the nearly rear end cap of motor shell outer peripheral face is provided with several air inlets, and air inlet is communicated with motor shell inner chamber, between motor shell and front end housing, be provided with air blast, described air blast comprises air blast shell and flabellum, fan blade rotating is automatically connected in air blast shell, the import of air blast shell is communicated with motor shell inner chamber, flabellum is connected on output shaft, from the indrawn cold air in motor rear end under the effect of gathering of motor shell, form stronger air-flow in motor shell inner accumulated, air-flow outlet from air blast after motor shell inner chamber is discharged, and air blast is located near the position that output shaft stress relatively concentrates, therefore air-flow can be taken away the heat at output shaft stress concentrated position place rapidly, ensure the not impact of received heat of output shaft, keep original intensity, and then the useful life of guarantee output shaft, and flabellum is between front end housing and rotor, under the position-limiting action of air blast shell and front end housing, how long do not appoint the high speed continuous running of output shaft, also can from the output shaft of motor, not come off because lasting vibration causes flabellum, therefore stability in use is better, and flabellum is fixedly connected on output shaft, by motor driving, independent motor is not set in addition yet, can effectively reduce energy consumption.Therefore the utlity model has energy consumption relatively low, output shaft is had to good radiating effect, do not affect the good feature of output shaft normal service life and stability in use.
