Coaxial induction and excitation generator

Abstract

The invention discloses a coaxial induction and excitation generator and relates to the coaxial induction and excitation generator with two kinds of output voltage, which solves the problem that two generators are separately designed and manufactured or a wire head is drawn from a coil when two kinds of voltage are required for the convention generator, the problem that the two generators have high cost and large occupied space when separately designed and the problem that the two kinds of voltage cannot be adjusted separately when the wire head is drawn from the coil. The generator consists of two sets of independent stator iron cores and two sets of rotor iron cores, wherein the two sets of independent stator iron cores are fixed in a base and provided with an even number of magnetic poles which are more than 2 respectively; the two sets of rotor iron cores are fixed on rotating shafts; and each magnetic pole is punched with an even number of slots. By arranging the two sets of stator iron cores and the two sets of rotor iron cores in the base of the generator, one generator can output two different kinds of voltage and achieve the functions of two generators, so that the size of the generator is reduced, the cost of the generator is lowered, two sets of independent stator excitation current can be separately adjusted, and electricity and magnet are not interfered with each other.

Description

technical field [0001] The invention relates to a generator, in particular to a coaxial induction excitation generator with two output voltages. Background technique [0002] At present, when generators with two voltages are required in use, one of the known design methods is to design two generators separately, and each generator provides a voltage respectively, so that there are actually two generators, and its disadvantages are: ① High cost; ②The weight is heavy, which will limit the scope of use of the generator in places with special requirements for the weight of the generator; ③The generator takes up a lot of space, which will limit the scope of use of the generator in places where the space is tight and narrow ;④ There are windings or permanent magnets on the generator rotor. Due to the mechanical strength, the generator speed cannot be too high, otherwise it will cause deformation or fall off that will affect the service life of the generator and cause the generator...

[0002] At present, when generators with two voltages are required in use, one of the known design methods is to design two generators separately, and each generator provides a voltage respectively, so that there are actually two generators, and its disadvantages are: ① High cost; ②The weight is heavy, which will limit the scope of use of the generator in places with special requirements for the weight of the generator; ③The generator takes up a lot of space, which will limit the scope of use of the generator in places where the space is tight and narrow ;④ There are windings or permanent magnets on the generator rotor. Due to the mechanical strength, the generator speed should not be too high, otherwise it will cause deformation or fall off that will affect the service life of the generator and the generator cannot be used normally.

The second known design method is to use taps in the winding to obtain two voltages. The disadvantage is that the two voltages are related to each other. When one voltage is adjusted, the other voltage will also change accordingly. Affect the performance and use effect of the generator, and cannot meet the user's requirements
