Description
Technical field
The utility model relates to a kind of mini-type bi-pole single-phase generator.
Background technology
The winding slot and the spindle line embedding groove of the rotor of bi-pole single-phase generator are parallel to each other at present, cause not having angle between rotor and the stator core like this, influence to the waveform of output voltage is very big like this, make output voltage waveforms very poor, indentation, common generator output voltage irregularity of wave form is to increase voltage-form distortion rate with load to increase, the sinusoidal aberration rate of output voltage waveforms is from 15%-25%, when the sinusoidal aberration rate of waveform very big, harmonic component is very heavy, thereby to consuming device, particularly the impact to capacitive load is very big, and the heat dispersion of present in addition single-phase generator is poor.
Summary of the invention
The utility model provides a kind of mini-type bi-pole single-phase generator, and it greatly reduces the sinusoidal aberration rate of generator output voltage waveform, and the adaptability of capacitive load is strengthened greatly, and helps the consuming device life-time dilatation.
The utility model has adopted following technical scheme: a kind of bi-pole single-phase generator, it comprises rotor and stator, rotor stretches in the stator, the upper and lower of described rotor is distributed with winding slot, is provided with winding coil in the both sides unshakable in one's determination of stator, and described winding coil is the secondary winding, upper and lower at the iron core of rotor is equipped with winding assembly, winding assembly is for being symmetrical arranged, and the outer surface branch of the iron core of stator has radiating groove, and radiating groove is that indentation distributes.
Described winding assembly is set to damping and amortization strip winding, and damping and amortization bar shaped winding comprises some damping blocks and baffle plate, and damping block crosses iron core and is connected with the baffle plate that is positioned at both sides unshakable in one's determination.Described damping block and baffle plate are iron, aluminium and copper.Described winding slot is set to oblique slot.
The utlity model has following beneficial effect: the outer surface of the utility model stator core is distributed with radiating groove, and radiating groove is that indentation distributes, and can improve the efficient of ventilation and heat so greatly, reduces electric machine temperature rise.The utility model is provided with damping and amortization strip winding on the iron core of rotor, so not only can improve the magnetic line of force distribution stability of rotor, and the AC impedance and the dc impedance of rotor have been reduced, the magnetic hysteresis eddy current loss of rotor is reduced, temperature reduces, thereby effectively controls the temperature rise of rotor winding.The utility model electrical machine insulation grade be the F level, fixed rotor temperature rise all be lower than 105K, winding coil is the secondary winding, make the magnetic field of stator yoke portion more even like this, formed magnetic field is Sine distribution, has slackened the influence of harmonic wave to output voltage waveforms, thereby makes output voltage waveforms all more approaching sine wave when unloaded and load, the sinusoidal aberration rate of voltage waveform is reduced in 5%, adaptability to capacitive load is stronger, helps the consuming device life-time dilatation, applied range.
