Abstract

The invention discloses a small-sized two-pole single-phase generator, comprising a rotor (1) and a stator (2), wherein, the rotor stretches into the stator (2); coiling grooves (3) are distributed at the upper part and the lower part of the rotor (1); winding coils (4) are arranged at the two sides of the iron core of the stator (2); the winding coils (4) are secondary windings; winding assemblies are arranged at the upper part and the lower part of the iron core of the rotor (1), and are arranged symmetrically; and sawtooth-shaped radiating grooves (7) are distributed on the outer surface of the iron core of the stator (2). The small-sized two-pole single-phase generator of the invention greatly lowers the waveform sinusoidal aberration rate of the voltage output by the generator, greatly enhances the adaptability to the capacitive load, and is beneficial for prolonging the service of the electric appliances.

Description

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...
