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.
Keywords: Brushless synchronous machine, magnetic field analysis, working principle, brushless excitation system
