Description
Technical field
The present invention relates to a kind of three phase electric machine, particularly relate to a kind of light-weight electric automobile threephase asynchronous machine.
Background technology
Threephase asynchronous machine has that torque is large, power density is high, reliable, control efficiency advantages of higher, is the focus of current power automobile research and development.
Magneto drives and is divided into brshless DC motor and permagnetic synchronous motor.Brshless DC motor has that torque is large, power density is high, position probing and the advantage such as control method is simple, but is difficult to reach perfect condition due to converting commutating current, the problem such as torque pulsation, vibration noise therefore can be caused large; Be applicable to some and some not too high electric automobile is required for the speed of a motor vehicle.Permagnetic synchronous motor has the features such as control precision is good, torque density is large, torque is steady, noise is low, drives have higher using value for electric automobile; Being subjected to the great attention of domestic and international electric automobile circle at present, is a kind of more satisfactory electric automobile driving apparatus.
But current threephase asynchronous machine exists that volume is large, complex structure, cost are high, and does not have survey rotating speed functions, is difficult to realize speed regulating control, can not meets the needs of Hyundai Motor.
Summary of the invention
For the above-mentioned defect existed in prior art, the present invention aims to provide that a kind of volume is little, lightweight, structure is simple, have the light-weight electric automobile threephase asynchronous machine surveying rotating speed functions.
To achieve these goals, the present invention is by the following technical solutions: it comprises and is located at stator module in casing and rotor assembly, described casing is made up of shell, the front end housing being separately fixed at shell two ends by screw rod and rear end cap, stator module is fixed in shell, and rotor assembly is bearing on front end housing and rear end cap by bearing; Rear end cap is fixed with cover plate, rotating shaft is fixed with gear, position cover plate corresponding to this gear is fixed with speed probe.
Casing is fixed with the terminal box of band binding post.
Compared with the prior art, the present invention is squirrel-cage threephase asynchronous, reports transducer owing to adding, therefore can the rotating speed of motor in real time, the input by the corresponding adjustment motor of controller, thus realize Electric Machine Control.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: terminal box 1, stator module 2, shell 3 rotor assembly 4, front end housing 5, screw rod 6, rear end cap 7, cover plate 8, gear 9, speed probe 10.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Figure 1: casing is made up of shell 3, the front end housing 5 being separately fixed at shell 3 two ends by screw rod 6 and rear end cap 7, and stator module 2 is fixed in shell 3, rotor assembly 4 is bearing on front end housing 5 and rear end cap 7 by bearing; This rear end cap 7 is fixed with cover plate 8, rotating shaft is fixed with gear 9, position cover plate 8 corresponding to this gear 9 is fixed with speed probe 10.
For the ease of wiring, simultaneously also in order to safety, described casing is fixed with the terminal box 1 of band binding post.
Claims (2)
1. a light-weight electric automobile threephase asynchronous machine, comprise and be located at stator module in casing and rotor assembly, it is characterized in that: described casing is made up of shell (3), the front end housing (5) being separately fixed at shell (3) two ends by screw rod (6) and rear end cap (7), stator module (2) is fixed in shell (3), and rotor assembly (4) is bearing on front end housing (5) and rear end cap (7) by bearing; This rear end cap is fixed with cover plate (8), rotating shaft is fixed with gear (9), the upper position corresponding to this gear (9) of cover plate (8) is fixed with speed probe (10).
