Abstract
In order to solve problems of complicated structure and huge volume of synchronous machine (SM), this paper presents a brushless synchronous machine with the structure of single stator core and single rotor core. Power windings and excitation windings of stator are laid in the same stator core. Correspondingly, DC excitation windings and AC windings of rotor are laid in the same rotor core, fixed in the machine's rotor by the rotating rectifier which is formed of commutation diodes. Magnetic field of the new structure machine is analyzed and calculated by ANSYS. The results show that the designed brushless synchronous machine has characteristics such as simple structure and superior performance. Therefore, it has a good application prospect.
