Abstract
The present invention discloses a DC motor for a pure electric vehicle, belonging to a permanent magnet synchronous DC motor. The invention aims to provide an electric vehicle driving motor with a small volume, a light weight, a simple structure and convenient regulation. The motor comprises a rotor assembly and a stator assembly arranged in a shell which is formed by a shell body (5), a front end cover (2) and a back end cover (10), and the front end cover (2) and the back end cover (10) are fixed at two ends of the shell body respectively. The rotor assembly (3) goes through the stator assembly (4) fixed in the shell body (5) and is supported by the front end cover (2) and the back end cover (10) through a rotation shaft (1). The back end cover (10) is provided with a rotation transformer which is formed by a transformer stator (9) fixed to the back end cover (10) and a transformer rotor (8) which is in the transformer stator and is fixed to the end face of the rotation shaft (1). The motor has the advantages of stable performance and strong resistance ability to electromagnetic interference and is a driving motor for a pure electric vehicle.
Description
Technical field
The present invention relates to a kind of direct current machine, particularly relating to a kind of for driving the direct current machine of electric motor car.
Background technology
Magneto both had alternating current motor brushless structure, reliable, volume is little, control efficiency advantages of higher, be current power automobile research and development focus.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 permanent magnet synchronous electric machine technology is also immature, there is the defects such as volume is large, complex structure, cost are high, regulable control difficulty is large, poor anti jamming capability, the needs of Hyundai Motor can't be met.
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, be convenient to the pure electric vehicle direct current machine that regulates and controls.
To achieve these goals, the present invention is by the following technical solutions: it comprises and is located at casing rotor assembly and stator module, described casing is made up of housing, the front end housing being fixed on these housing two ends and rear end cap, and rotor assembly is through fixing stator module in the housing and by shaft support on front end housing and rear end cap; Rear end cap is provided with resolver, this resolver by the resolver stator be fixed on rear end cap, be arranged in this resolver stator and the transformer rotor being fixed on rotating shaft end face is formed.
Casing is fixed with terminal block and straight coupling.
Compared with the prior art, the present invention adopts knockdown casing and rotor assembly owing to have employed, and therefore both can conveniently process and assemble, again reduce cost; And resolver can monitor the running status of motor in real time.In addition, owing to have employed all-sealed structure, therefore both can dust-proof, in turn enhance anti-electromagnetic interference capability, provide good guarantee for realizing Electric Machine Control.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: rotating shaft 1, front end housing 2, rotor assembly 3, stator module 4, housing 5, terminal block 6, straight coupling 7, transformer rotor 8, resolver stator 9, rear end cap 10.
Embodiment: the invention will be further described below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: casing by housing 5, respectively airtight be fixed on these housing two ends front end housing 2 and rear end cap 10 form.Stator module 4 is formed by being fixed on the iron core being inlaid with winding in housing 5, and by passing, stator module 4 is bearing in the rotating shaft 1 on front end housing 2 and rear end cap 10 to rotor assembly 3 respectively, the magnet steel be fixed in this rotating shaft is formed.Rear end cap 10 is provided with resolver, this resolver by the resolver stator 9 be fixed on rear end cap 10, be arranged in this resolver stator and the transformer rotor 8 being fixed on rotating shaft 1 end face is formed.For the ease of wiring, be fixed with terminal block 6 and straight coupling 7 on the housing.
Claims (2)
1. a pure electric vehicle direct current machine, comprise and be located at casing rotor assembly and stator module, it is characterized in that: described casing is made up of housing (5), the front end housing (2) being fixed on these housing two ends and rear end cap (10), rotor assembly (3) is bearing on front end housing (2) and rear end cap (10) through the stator module (4) be fixed in housing (5) and by rotating shaft (1); Rear end cap (10) is provided with resolver, this resolver by the resolver stator (9) be fixed on rear end cap (10), be arranged in this resolver stator and the transformer rotor (8) being fixed on rotating shaft (1) end face is formed.
