Problems solved by technology

[0002] At present, the winding groove of the rotor of the two-pole single-phase generator and the embedding groove of the spindle are parallel to each other, so that there is no angle between the rotor and the stator core, which has a great influence on the waveform of the output voltage and makes the waveform of the output voltage very poor. , in a sawtooth shape, the distortion rate of the output voltage waveform of an ordinary generator increases with the increase of the load, and the sinusoidal distortion rate of the output voltage waveform ranges from 15% to 25%. When the sinusoidal distortion rate of the waveform is large, the harmonic component is very heavy , so it has a great impact on electrical appliances, especially on capacitive loads. In addition, the heat dissipation performance of current single-phase generators is relatively poor.

technical field [0001] The invention relates to a small two-pole single-phase generator. Background technique [0002] At present, the winding groove of the rotor of the two-pole single-phase generator and the embedding groove of the spindle are parallel to each other, so that there is no angle between the rotor and the stator core, which greatly affects the waveform of the output voltage and makes the output voltage waveform very poor. , in a sawtooth shape, the distortion rate of the output voltage waveform of an ordinary generator increases with the increase of the load, and the sinusoidal distortion rate of the output voltage waveform ranges from 15% to 25%. When the sinusoidal distortion rate of the waveform is large, the harmonic component is very heavy , so it has a great impact on electrical appliances, especially on capacitive loads. In addition, the heat dissipation performance of current single-phase generators is relatively poor. Contents of the invention [0...
