A new brushless and permanent magnet less synchronous generator is reported in this work. Contrary to traditional brushless synchronous generators that use an extra machine along with rotating diode rectifier, the proposed machine houses the main and the exciter machine in the same frame. Thus the size, cost, and efficiency of the proposed system are expected to be more competitive. Magnetic decoupling between two windings wound for different number of poles is exploited to create such generators. Two synchronous machines are connected in cascade and housed in the same frame with the armature of the exciter machine put on the rotor and field on the stator. The main machine is a standard synchronous generator. For preliminary investigations, an experimental machine is made having four poles and six poles for main machine and exciter machine, respectively. While the armature of the exciter machine can be wound for different number of phases, a three-phase winding is considered that is fed to rotating rectifier. The output of the rectifier provides field excitation to the main synchronous machine. Extensive simulation studies are carried out using MAXWELL 2D and MATLAB/Simulink. Experimentations conducted on the laboratory prototype match well with the simulations confirming the effectiveness of the proposed generation system.
