Description
Technical field
The utility model belongs to technical field of generators, specifically, relates to a kind of mini-type bi-pole single-phase generator rotor.
Background technology
Existing mini-type bi-pole single-phase (brush or brushless is arranged) generator (mainly be made up of armature spindle and iron core by the rotor of 0.45KW～18KW), rotor winding groove on the iron core is the straight trough structure, it is the axial line that winding slot is parallel to armature spindle, its shortcoming is that the generator output voltage waveform is very poor, indentation, the sinusoidal aberration rate of waveform is between 15%～25%, harmonic component in the waveform is very heavy, thereby to consuming device, particularly the impact to capacitive load is very big, cause the damage in advance of consuming device, make the range of application of the type motor be subjected to certain restriction.
Three, summary of the invention:
The purpose of this utility model provides a kind of mini-type bi-pole single-phase generator rotor, and the output voltage waveforms that solves existing mini-type bi-pole single-phase generator is poor, the sinusoidal aberration rate height of waveform, the problem that the scope of application is very limited.
For addressing the above problem, mini-type bi-pole single-phase generator rotor described in the utility model, iron core are fitted on the armature spindle, and iron core is made of the punching that stacks, winding slot on the iron core is 4～8 grooves, and the axial line of winding slot and armature spindle is 3 °～15 ° angles; Be provided with two cover damping winding on iron core, every cover damping winding is made up of amortisseur bar and damping sheet, and damping sheet is arranged on the iron core both ends of the surface, and two ends reliably were connected on the damping sheet after 4～6 amortisseur bars passed iron core.
The winding slot of iron core adopts flume structure in the utility model, makes rotor and is embedded between the output winding in the spindle iron core at an angle to each otherly, has weakened the influence of odd harmonic to output voltage waveforms; Because of being subjected to the magnetic force distribution, output voltage waveforms influences, after installing two cover damping winding in the rotor core additional, make the distribution of rotor magnetic line reach best, weaken of the influence of the negative phase-sequence magnetic field of spindle output winding generation to waveform, and can reduce the friendship of rotor, straight impedance, the magnetic hysteresis eddy current loss of rotor is reduced, and temperature rise reduces.Improve magnetic circuit thereby reach, the purpose of improvement output waveform.On the basis that guarantees other output performance of generator, the sinusoidal aberration rate of original generator voltage waveform can be reduced in 5% from 15%～25%, greatly improved output voltage waveforms, make the range of application of mini-type bi-pole single-phase generator more extensive, the adaptability of capacitive load is strengthened greatly.
The utility model has the advantages that: output voltage stabilization, waveform is good, and more approaching sine wave is stronger to the adaptability of capacitive load, helps the consuming device life-time dilatation, thereby the scope of application of motor is more extensive.
