Abstract
The invention relates to a water cooling motor of an electric vehicle, which comprises a motor stator and a motor rotor, and is characterized in that the motor stator and the motor rotor are rotationally and fixedly connected with a motor shaft through an outgoing line side bearing and a water tank side sealing bearing to form a sealing cooling water body, a rotating fan is arranged on the motor shaft, and a cooling water tank is arranged between a water tank side cover and a rotor shell. The motor shaft is equipped with a motor water outlet and a motor water inlet. The water cooling motor of the electric vehicle has simple, compact and reasonable structure, rapid operation speed, high efficiency, big torque, long service life and strong compressive resistance current-withstanding capability, can achieve the purposes of energy exchange and controlling the temperature of working environment, achieving the steady operation of a big power motor products, prolonging the service life and increasing the efficiency.
Description
Technical field
The present invention relates to a kind of water-cooled motor of motor vehicle, specifically electric bicycle, luxurious electric motor car, battery-operated motor cycle and light-weight electric automobile (being called for short " motor vehicle ") are gone up a kind of recirculated water cooling motor of using.
Background technology
In prior art, with the recurrence of market hommization and practicability consumption concept, following electronic vehicle development is categorized as bicycle and electronic vapour two classes of rubbing.The motor of electric vehicles mainly comprises motor stator and motor rotor, and described motor stator comprises motor reel, iron core, winding coil, and iron core is installed on the motor reel, and winding coil is arranged on the iron core.Described motor rotor comprises motor wheel hub, rotor case, the firm sheet of magnetic, and the firm sheet of magnetic is arranged on the winding coil and is contained in the rotor case.The motor power (output) of this kind structure is big, the efficient height; The voltage height, electric current is big; Caloric value is big under big electric current running status, the heat radiation difficulty; Electronic component useful life is short, can not satisfy that manned motor vehicle is high-speed, the growth requirement of high pulling torque.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of water-cooled motor of motor vehicle is provided, the speed of service is fast, efficient is high, moment of torsion is big, the life-span is long, and the resistance to compression withstanding current capability is strong.
According to technical scheme provided by the invention, the water-cooled motor of motor vehicle comprises motor stator and motor rotor, described motor stator comprises motor reel, iron core, winding coil, described motor rotor comprises motor wheel hub, rotor case, the firm sheet of magnetic, feature is that motor stator and motor rotor are fastened on the motor reel by outlet side bearing, the revolution of tank side seal bearing, form the annular seal space of sealing cooling water body, rotary fan is installed on motor reel, is provided with bosh between tank side lid and the rotor case.Described motor reel is provided with motor water outlet and motor water inlet.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; The speed of service is fast, efficient is high, moment of torsion is big, the life-span is long, and the resistance to compression withstanding current capability is strong; Can realize that energy exchange and operating ambient temperature are controlled, reach the stable operation of high power motor product, can increase the service life and the purpose of improved efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: comprise motor reel 1, motor water outlet 2, rotary fan 3, iron core 4, the firm sheet 5 of magnetic, motor water inlet 6, tank side lid 7, cool cycles water body 8, motor wheel hub 9, bosh 10, winding coil 11, outlet side bearing 12, tank side seal bearing 13, motor stator 14, motor rotor 15 and rotor case 16 etc.
After the winding coil 11 energising operations of the present invention, because the effect in the firm sheet of magnetic 5 magnetic fields, motor rotor 15 produces reverse cut power, produces a large amount of heats in electric energy, the mechanical energy transfer process simultaneously.General small power motor reaches the heat radiation balance by motor rotor 15 (water-bearing channel side lid 7 etc.) housing, and temperature remains between 50～60 ℃.High power motor must pass through other radiating modes, to reach and to satisfy practical function.
Secondly, cool cycles water body 8 enters bosh 10 through motor water inlet 6, when flowing through bosh 10 surperficial, the low temperature water body is through rotary fan 3 rotations, carry out becoming after the full and uniform exchange heat the higher water body that carries a large amount of heats, discharge from motor water outlet 2 again, water body was taken away big calorimetric after temperature raise, stablize motor stator 14 operating ambient temperatures about 30 ℃, realize that energy exchange and operating ambient temperature are controlled, reach the stable operation of high power motor product, increase the service life and the purpose of improved efficiency.
In sum, the speed of service of the present invention is fast, efficient is high, moment of torsion is big, the life-span is long, the good electric vehicles high power motor of resistance to compression withstanding current capability is achieved and promotes.
