    摘要： The system described herein is particularly adapted to convert mechanical energy from a wind or hydraulic driven turbine into electric energy and comprises: an exciter generator and a main generator in a housing traversed by a rotatable shaft; the exciter generator consists of permanent magnet mounted to the housing envelope and of a rotor mounted to the shaft and having a one-phase winding, the rotor being made of non-magnetic material to eliminate cogging and static torque associated with permanent magnet excitation; the main generator consists of a three-phase stator winding on a magnetic core mounted to the housing envelope and of a pole-type rotor mounted to the shaft, the rotor having a winding wound on a magnetic core; a rectifying bridge is rotatably mounted to the shaft and is connected to the one-phase winding of the rotor of the exciter generator and to the winding of the main generator rotor so that the rotation of the shaft as a result of mechanical energy generates a three-phase electric energy output from the stator winding.
