Abstract
The utility model relates to a vehicle generator. The structure comprises a rotor made of a plurality of layers of silicon steel sheets, a stator and an armature winding. The utility model is characterized in that the rotor is in a gear shape and without a magnet or a winding. The stator is connected into an annular shape through a plurality of sections of overlapped and pressed silicon steel sheets. Rare earth magnetic steel and the armature winding are both fixed and assembled on the stator. The generator has the advantages of novel simple structure, labor saving on manufacture occasion and high precision. Because of the high intensity of the rotor and favorable balance heat rejection, the generator has the advantage over the existing excitation-type permanent-magnet-type double-current generator on the aspects of manufacture and usage.
Description
The utility model relates to a kind of electric generator of vehicle, and its structure comprises rotor, stator and the coil windings that the multilayer silicon steel sheet is made.
With the existing patent application of the generator of motor vehicle dynamic power, as Chinese patent
96213869.X its architectural feature is for being equipped with the polylith magnet in rotor, this motor moves machinery and electromagnetic balance is difficult for assurance, and assembles time-consumingly, and intensity is not high.
The purpose of this utility model provides a kind of electric generator of vehicle, and this generator drives with motor vehicle power, and its rotor, stator repeatedly are pressed into through punching by the multilayer silicon steel sheet, and do not have magnet on the rotor, winding and slip-ring brush.
The purpose of this utility model is realized by following structure:
The rotor 1 and the stator 2 of this generator are gear-like and ring-type, stator 2 is repeatedly pressed silicon steel sheet to stick with glue mode by even number section (as 4,6,8, section) or is connected into ring-type integral body with non-magnet_conductible material, be fixed with a rare earth magnetic steel 3 between each section, its height is identical with the thickness of rotor 1, stator 2.
The utility model also can be realized by following structure:
Stator 2 inboards corresponding to gear-like rotor 1 are the teeth groove shape, and stator teeth groove number is one times of rotor teeth groove number.
Generator armature winding 4 is in the form of a ring on stator tooth 5, and the coil winding-direction on each adjacent stators tooth 5 is opposite.
Effect of the present utility model and advantage are: rare earth magnetic steel 3, the armature winding 4 of this generator all are contained on the stator 2.Rotor 1 no magnet, no winding, balance, thermal diffusivity are all good, and the intensity height can bear bigger centrifugal force and temperature rise.The utility model overall structure is simple, and armature winding 4 lead-out wires directly are communicated with external circuit.No matter also be to use in manufacturing, this generator all is better than existing excitation, magneto double current generator.This generator can be made complete machine separately and use, and also stator and rotor directly can be contained in supporting use on the motor vehicle.
Description of drawings:
Fig. 1 is generator amature, stator front view
Fig. 2 is the directly scheme of installation on motor vehicle of generator amature, stator
Fig. 3 makes the complete machine sectional side view separately for generator
Embodiment 1:
As shown in Figure 1, the rotor 1 and the stator 2 of this generator are gear-like and ring-type, and stator 2 repeatedly presses the silicon steel sheet mode of sticking with glue to connect into ring-type integral body by 4 sections, is fixed with a rare earth magnetic steel 3 between each section, and its height is identical with the thickness of rotor 1, stator 2.
Stator 2 inboards corresponding to gear-like rotor 1 are the teeth groove shape, and stator teeth groove number is 16 pairs, and rotor teeth groove number is 8 pairs.
Generator armature winding 4 is in the form of a ring on stator tooth 5, and the coil winding-direction on each adjacent stators tooth 5 is opposite.
As shown in Figure 2, flywheel fixes on generator amature 1 and the motor vehicle, and 2 of stators are fixed on the motor vehicle casing.
Embodiment 2:
As shown in Figure 3, generator amature 1, stator 2 structures are identical with last example, and in aggregates with end cap, bearing, axle, support assembling.
