The novel brushless excitation methods for wound rotor excitation synchronous generators

2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER), 2016
In this paper, two novel brushless excitation methods for wound rotor excitation synchronous generators are proposed in this paper. Compared with the electric excitation synchronous generators with an exciter, these two kinds of generators can integrate the function of the exciter into the main generator. The exciter can be eliminated. The axial length

A Brushless Adjustable Excitation Generator

Elektrichestvo, 2022
Wind turbines are further developed toward improving their reliability and efficiency, and reducing maintenance costs during long-term operation. For this purpose, synchronous generators with excitation from permanent magnets are used, the parameters of which determine in many respects the efficiency and dimensions of the power plant as a whole.
