Abstract

The invention provides a brushless alternating current power generator which is simple in structure, high in motor reliability and maintainability, free of a carbon brush slip ring or rotation rectifying and overcomes the shortcomings of low reliability, complex structure, high cost, limited rotary speed and the like of the existing alternating current power generator. Each power generation unit comprises a stator and a rotor; an air gap is reserved between the stator and the rotor; the rotor comprises at least two rotor salient poles; the stator comprises stator iron cores and excitation brackets; the excitation brackets and the stator iron cores are fixedly connected; excitation windings are distributed on the excitation brackets; each excitation bracket forms a magnetic flux access to form an N pole and an S pole at the two ends of the excitation bracket respectively; a stator groove is formed in each stator iron core; armature windings are arranged in the stator grooves; two groupsof armature windings are arranged on the stator iron cores corresponding to the space between the two corresponding adjacent rotor salient poles; and the two groups of armature windings are in series-opposing connection. In addition, the invention also provides a power generation technology adopting the brushless alternating current power generator.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a brushless alternator and power generation technology. Background technique [0002] The current mainstream alternator generally adopts the rotor excitation method, that is, the excitation magnetic field is generated in the rotor, and the external power equipment drives the rotor to rotate, thereby driving the excitation magnetic field to rotate, and cutting the armature winding distributed in the stator to generate alternating current. For the electric excitation alternator, it passes the direct current into the rotor excitation winding through the slip ring brush or the rotating rectification module to generate the excitation magnetic field. Since the excitation winding is on the rotor, it must pass the carbon brush slip ring or rotating rectification The direct current is passed into the rotor, the structure is complicated, the cost is high, and the reliability is no...
