Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0018] As shown in Figures 1 to 5, a 12KW small two-pole single-phase generator is composed of a rotor 1 and a spindle 2. The iron core of the rotor 1 is provided with two sets of damping windings, and each set of damping windings consists of damping strips 3 and The damping plate 4 is composed of the damping plate 4, which is arranged on both ends of the iron core. After the damping bar 3 axially passes through the iron core, the two ends are reliably welded (spot welded) to the damping plate 4; the winding coil 2a on the spindle 2 is Equidistant two-pole winding structure.

[0019] figure 2 There are four damping strips 3 in each set of damping windings on the core of the middle rotor 1, the cross section of the damping strips 3 is circular and the diameter is between 2-8mm, and the thickness of the damping plate 4 is 1-8mm. The damping strip 3 a...

Abstract

The invention provides a small-scale bipolar single-phase generator, composed of a rotor and a stator, where the iron core of the rotor is provided with two damping windings, each composed of a damping bar and a damping plate, the damping plate arranged on two end faces of the iron core and the two ends of the damping bar axially passes through the iron core to be reliably connected with the damping plate; the stator winding coil is of a structure of equidistant bipolar winding. The winding slot on the rotor iron core makes an included angle of 3deg. - 5deg. with the wire embedding slot on the stator iron core. The outer surface of the stator iron core is distributed with axial grooves. The output voltage of the invention is stable and has good waveform, nearer to sine wave and having stronger adaptability to capacitance-type load, beneficial to prolonging the life of electric appliances and thus having a wide application range.

Description

technical field [0001] The invention relates to a generator, especially a small two-pole single-phase generator. Background technique [0002] At present, the rotor winding grooves and spindle embedding grooves of small two-pole single-phase generators (0.45KW~18KW) on the market are straight groove structures, that is, the centerlines of the rotor winding grooves and the spindle embedding grooves are parallel to the power generator. Therefore, there is no angle between the rotor coil and the output winding embedded in the core of the spindle. When the generator is working, odd harmonics such as 3, 5 and 7 have a great influence on the output voltage waveform, making The output voltage waveform is very poor, it is jagged, and the sinusoidal distortion rate of the waveform is usually between 15% and 25%. The harmonic component in the waveform is very heavy, so it has a great impact on electrical appliances, especially on capacitive loads. The prematur...
