CN2772109Y - Automobile generator with self-excitation function - Google Patents

Abstract

The utility model relates to a generator, particularly an automobile generator with a self-excitation function. The utility model is provided with a end cover, a magnetic rotor is arranged on a center shaft which is arranged in an inner cavity of the end cover, a bearing is arranged on the magnetic rotor and is fixedly connected with the end cover, a stator is fixedly arranged on the inner wall of the end cover and an excitation winding is fixedly arranged between the magnetic rotor and the stator. Under the condition of the failure of a storage battery which is brought by the automobile, the automobile generator with a self-excitation function can normally work, and the safe running of the automobile can be ensured.

Description

Automobile current generator with self-excitation function

Affiliated technical field

The utility model relates to a kind of generator, particularly relates to a kind of automobile current generator with self-excitation function.

Background technology

At present, the automobile current generator generating all is to switch on to field winding by the tyre storage battery, produce magnetic field, when external force is ordered about the generator amature rotation, stator winding inside will produce electric current, thereby mechanical energy is transformed into electric energy, and automobile electric appliance system is powered, that is to say that the confidential generating of automobile generating must have storage battery power supply ability operate as normal.

Summary of the invention

Must be with the shortcoming of storage battery in order to overcome the automobile current generator generating, the utility model provides a kind of automobile current generator with white sharp function.

Technical solution adopted in the utility model is: a kind of automobile current generator with self-excitation function, has end cap, end cap lumen centers axle is provided with magnet rotor, magnet rotor is provided with bearing, bearing is fixedlyed connected with end cap, between end cap, be set with stator, between magnet rotor and stator, be set with excitation winding.

Automobile current generator with self-excitation function of the present utility model, on the automobile under the situation with battery malfunction, generator still can operate as normal, has guaranteed the safety traffic of automobile.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1. end cap 2. magnet rotors 3. bearings 4. stators 5. excitation winding

Embodiment

A kind of automobile current generator as shown in Figure 1 with self-excitation function, has end cap 1, end cap 1 lumen centers axle is provided with magnet rotor 2, magnet rotor 2 materials are 42CrMoA, this material has remanent magnetism, and rotor 2 is provided with bearing 3, and bearing 3 is fixedlyed connected with forward and backward end cap 1, between forward and backward end cap 1, be set with stator 4, between magnet rotor 2 and stator 4, be set with excitation winding 5.When generator rotor 2 motions under external force, stator 4 can produce little electric current, feeds back to excitation winding 5, thereby produces magnetic field, reaches the purpose of generator for electricity generation, and does not need to rely on storage battery power supply.

Claims (1)

1. automobile current generator with self-excitation function, it is characterized in that: have end cap (1), lid (1) lumen centers axle is provided with magnet rotor (2), magnet rotor (2) is provided with bearing (3), bearing (3) is fixedlyed connected with end cap (1), on end cap (1) inwall, be set with stator (4), between magnet rotor (2) and stator (4), be set with excitation winding (5).
