Abstract
The utility model discloses a cooling motor comprising a motor shell, a stator, a rotor and a spindle which are arranged in the motor shell, and a fan cooling device which is arranged on one end of the motor shell. The fan cooling device is connected with the spindle. The motor shell has an integrated structure composed of by an inner layer and an outer layer which are formed by performing hot extrusion on aluminium alloy integrally. A hollow circulating water channel is arranged between the inner layer and the outer layer. A motor fan cover is fixedly installed on the periphery of the fan cooling device. After cooling water is injected into the hollow circulating water channel, most of the heat generated by the motor is taken away, and then cooling is performed through a fan behind the spindle, so the rotor cooling function can be realized, and the working temperature of the motor can be reduced, so that the service life of the motor can be effectively prolonged.
Description
Technical field
The utility model relates to a kind of radiating motor.
Background technology
Development along with Computerized Numerical Control technology and electric automobile field, has had requirements at the higher level to the technical performance of servomotor, drive motors.For example, in the application of the linear electric motors Driving technique of numerical control of machine tools servo system, high speed and high precision processing lathe, automotive field except driving motor of electric vehicle, automotive electronics servo system is if the motor of electronics power steering and line traffic control stop lamp industry is except needs have that efficiency is high, pushing force density is large, the good contour standard performance of controllability, must solve heat radiation, every magnetic problem simultaneously.The poor bottleneck that has become motor technology development of heat dispersion of current electric machine casing.For solving motor radiating problem, Japanology has been developed the outer refrigerating system of attaching spiral coil water circulation outside electric machine casing.This system bulk is larger, and because being takes away the operation principle of the outermost temperature of motor by spiral coil, and higher its cooling-down effect of motor internal of temperature is bad, can not really reach good cooling object.On housing after casting with aluminium alloy, there are the sand holes of pin hole shape; Processing cost is higher, processes more difficult; Weight is light not enough.
Summary of the invention
It is a kind of simple in structure that main purpose of the present utility model is to provide, the radiating motor of good heat dissipation effect.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of radiating motor, comprise electric machine casing, and be placed in stator, rotor and the rotating shaft in electric machine casing, and be placed in the fan radiator of electric machine casing one end, this fan radiator is connected with rotating shaft, described electric machine casing is that the internal layer and the skin that by aluminium alloy overall thermal, are pushed are into a single integrated structure, is provided with hollow cyclic water channel between internal layer and skin, and described fan radiator periphery is installed with motor fan housing.
As preferred technical scheme, described hollow cyclic water channel one end is made as water inlet, and the other end is made as delivery port.
As preferred technical scheme, described motor fan housing is provided with rotating shaft installing hole, has the heat sink strip of uniform projection on outer surface.
The beneficial effects of the utility model are:
At hollow cyclic water channel, inject after cooling water, most of heat that motor is produced is taken away, then by the fan cooling at rotating shaft rear, realizes the heat sinking function of rotor, has reduced machine operation temperature, thereby has effectively extended the useful life of motor.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is the schematic diagram of motor fan housing of the present utility model.
Embodiment
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of radiating motor, comprise electric machine casing 1, and be placed in stator 2, rotor 3 and the rotating shaft 4 in electric machine casing 1, and be placed in the fan radiator 5 of electric machine casing 1 one end, and this fan radiator 5 is connected with rotating shaft 4, and described electric machine casing 1 is the internal layer 11 that pushed by aluminium alloy overall thermal and outer 12 into a single integrated structure, between internal layer 11 and outer 12, be provided with hollow cyclic water channel 6, described fan radiator 5 peripheries are installed with motor fan housing 7.
Wherein, described hollow cyclic water channel 6 one end are made as water inlet 8, and the other end is made as delivery port 9; Described motor fan housing 7 is provided with rotating shaft installing hole 10, has the heat sink strip 13 of uniform projection on outer surface.
The beneficial effects of the utility model are:
At hollow cyclic water channel, inject after cooling water, most of heat that motor is produced is taken away, then by the fan cooling at rotating shaft rear, realizes the heat sinking function of rotor, has reduced machine operation temperature, thereby has effectively extended the useful life of motor.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
