The invention relates to a gasoline generator, in particular to a self-regulating magnetism-assisted permanent-magnet single-phase generator comprising a magnetism-assisted winding and a diode. The generator is characterized in that a permanent magnet is externally provided with a pole yoke, an empty slot is formed in the pole yoke, the magnetism-assisted winding is disposed in the empty slot, and two ends of the magnetism-assisted winding are connected with the diode. When the generator outputs current in single phase, rheologic magnetic flux with doubled frequency in the counter revolution direction is generated on a rotor, magnetic flux on the pole yoke of the rotor is maximum, alternating current generated by the magnetism-assisted winding is subjected to half-wave rectification by the diode to magnetically assist the rotor, and accordingly stability of output voltage is improved, and the size of assistance magnetism is self-regulated with the size of output current of the generator. The self-regulating magnetism-assisted permanent-magnet single-phase generator has the advantages of simple structure and high magnetism assisting capacity.
Description
technical field [0001] The invention relates to a gasoline generator, in particular to a permanent magnet single-phase gasoline generator. Background technique [0002] At present, gasoline generators are widely used. Due to the high calorific value, low efficiency, difficult maintenance, and weak ability of dragging motors of DC excitation generators, permanent magnet generators have small calorific value, high efficiency, simple structure, easy maintenance, and drag motors. It has strong capabilities and is welcomed by users, and its market is also expanding rapidly. However, there are also many problems in the permanent magnet gasoline generator, such as: the cost is high when the rotor permanent magnet is large, the excitation cannot be supplemented when the motor is started, and the voltage is too low. Contents of the invention [0003] According to the above deficiencies, the present invention proposes an automatic adjustment magnetism-assisted permanent magnet sing...
