Description
Technical Field
The utility model relates to a permanent magnet generator in the field of vehicle-mounted power supplies, in particular to a single-armature double-output permanent magnet generator.
Background
The existing double-output permanent magnet generator actually comprises 2 independent generators, wherein 2 sets of armatures and permanent magnet rotors are respectively arranged on the same shell and the same rotating shaft, and when the rotating shaft rotates, the two independent sets of armatures can output 2 paths of electric energy.
Although the generator with the structure can independently output a double-circuit power supply, the 2 sets of armatures and the permanent magnet rotor are arranged, and the winding end parts on the 2 sets of armatures occupy a large part of space of the generator, so that the whole size, particularly the axial size, of the generator is large, the structure is complex, and the reliability is poor.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and designs a single-armature double-output generator with simple structure and high reliability.
Realize above-mentioned utility model's technical scheme is: the stator comprises an armature core, a first path of winding and a second path of winding, a plurality of stator slots are uniformly distributed on the armature core, wherein one half of the stator slots are wound with the first path of winding, the other half of the stator slots are wound with the second path of winding, and the first path of winding and the second path of winding are 2 independent windings.
The rotor is a permanent magnet rotor and comprises a rotor shaft arranged in the middle of the shell and a rotor iron core arranged on the shaft.
The stator is embedded on the generator shell.
The 2 sets of independent windings have 2 winding ends in total.
And the one-way winding and the two-way winding are connected in a star shape.
The armature core is provided with 18 slots, one winding is distributed in 1-9 slots, the other winding is distributed in 10-18 slots, and the star point of the one winding and the star point of the two windings are independent respectively.
The generator disclosed by the utility model is a common permanent magnet rotor, different slots of two independent windings are arranged in the same armature core, the star points of the two windings are isolated, and the generator can simultaneously output two paths of power supplies when working, so that one machine has double outputs.
In order to avoid mutual influence of slot leakage inductance and harmonic leakage inductance generated when two sets of windings work, the two sets of windings are distributed according to all slots during product design, and the left side and the right side of each set of winding slot are placed in an armature slot.
By adopting the scheme, the technical effect that is achieved is as follows: the two sets of double three-phase windings are mutually independent in space, are not connected with each other by a circuit, are not mutually coupled on a magnetic circuit, and have extremely low mutual inductance of each phase winding, so that the isolation between two paths of output is realized, when one path of output changes, the output characteristic of the other path is not influenced, and the voltage and current fluctuation caused by mutual interference of the windings which are easy to occur when the double windings of the same armature are output is avoided. Therefore, the function of outputting two groups of independent power supplies by the single armature generator is realized. Therefore, the size, particularly the axial size, of the generator is reduced, the processing and manufacturing cost of the product is reduced, and the reliability of the product is improved.
