Problems solved by technology

[0002] In order to meet the requirements of grid-connected power generation, the permanent magnet generator needs to be able to adjust the output voltage with the fluctuation of the grid voltage or the change of the reactive load requirement. Now the rectification-inversion method is generally used to electronically adjust the output voltage. Due to the complex structure and the failure rate High cost and high cost have become a major obstacle for permanent magnet generators to be connected to the grid for power generation

Abstract

The invention relates to a generator, in particular to an adjustable voltage permanent-magnet generator, which comprises a main shaft, a rotor fixedly arranged on the main shaft, and stators arranged around the rotor. The rotor is fixedly arranged on the main shaft, a permanent magnet is fixedly arranged on the rotor, the stators are arranged on the main shaft through a bearing, the stators at least comprise a fixed stator and an adjustable stator on which a fixed stator coil and an adjustable stator coil are arranged respectively, phase lines of the fixed stator coil and the adjustable stator coil are correspondingly connected in series respectively, the fixed stator is fixedly connected with a generator bracket, the adjustable stator is connected to the generator bracket through a spring, and the adjustable stator is also provided with a deflection adjusting mechanism. The generator saves a rectification-inversion device in a parallel network of the permanent-magnet generator, has adjustable output voltage, lowers manufacturing cost greatly, and improves reliability of products.

Description

technical field [0001] The invention relates to a generator, in particular to an adjustable voltage permanent magnet generator. Background technique [0002] In order to meet the requirements of grid-connected power generation, the permanent magnet generator needs to be able to adjust the output voltage with the fluctuation of the grid voltage or the change of the reactive load requirement. Now the rectification-inversion method is generally used to electronically adjust the output voltage. Due to the complex structure and the failure rate High cost and high cost have become a major obstacle for permanent magnet generators to be connected to the grid for power generation. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable voltage permanent magnet generator which has a simple structure, can be directly connected to the grid, and can change the output voltage without a rectifier-inversion device. [0004] To achieve the above...
