LWG series three AC brushless synchronous generators, by introducing foreign advanced technology of well-known generators, are our newly developing products. Their body are constructed by steel shell and rotors are made as whole salient pole type with full damping. The generators adopt brushless self-exciting method and are controlled by automatic voltage regulator(AVR). They have the following features: Small size, light weight, good appearance and excellent performance. The technical performance and mounting dimensions of LWG series generators are conformity to international IEC34-1 and Chinese relevant standards of AC brushless synchronous generators, the generators reach advanced level in the world.
