Abstract

The invention discloses a modularized permanent magnet synchronous generator, comprising a rotor yoke, an rare earth permanent magnet, a triphase stator winding and a stator core, wherein the permanent magnet is evenly adhered on the inner surface of the rotor yoke, the stator tooth number of the stator core is two more than the piece number of the permanent magnet; a slot insulation layer is cladded on the stator teeth, the triphase stator winding is wound outside the slot insulation layer; the stator teeth of the stator core are evenly divided into six parts, winding of each phase is provided with two opposite parts and wounded on the corresponding slot, out-phase windings are only wounded in the six slots between two adjacent parts and same-phase windings are wounded in the rest of the slots. The invention can overcome the defects such as the large tooth space of the traditional permanent magnet synchronous generator and the like. Meanwhile, as the special centralized winding is utilized, the generator of the invention can greatly improve sine degree of voltage waveforms, reduce generator copper loss and improve generator power density.

Description

technical field [0001] The invention relates to a generator, in particular to a modular permanent magnet synchronous generator. Background technique [0002] Gasoline and diesel generating sets have a long history of development, and have gone through three major stages: belt drive, automatic voltage regulator to adjust excitation, and digital frequency conversion. At present, due to the use of high-power-density permanent magnet generators and digital controllers, the weight and volume of gasoline and diesel generator sets have been greatly reduced, and even portability has been realized, and the quality of output power has also been greatly improved compared with before. The permanent magnet generator is an important part of the entire gasoline and diesel generator set, and its volume, weight, efficiency, and torque fluctuation are directly related to the portability, efficiency, and noise level of the entire unit system. Therefore, improving the performance of the perman...
