BRUSHLESS GENERATOR USING HIGH-FREQUENCY ROTATING TRANSFORMER EXCITATION METHOD

摘要

PURPOSE: A brushless generator using high frequency rotating transformer excitation method is provided to supply the current to an exciter of a main generator by generating and rectifying a high-frequency voltage from a wire of a rotating transformer. CONSTITUTION: A brushless generator using high frequency rotating transformer excitation method includes a main generator(12) and a rotating transformer(11). The main generator(12) includes a fixing portion and a rotating portion. The rotating transformer(11) includes a fixing portion and a rotating portion. The fixing portion of the rotating transformer(11) is formed with a steel core(10) of the fixing portion and a coil(9) wound around the steel core(10) of the fixing portion. The rotating portion is formed with a steel core(8) of the rotating portion and a coil(7) wound around the steel core(8) of the rotating portion. A concave portion and a convex portion are formed on the inside of the steel core(10) of the fixing portion and the outside of the steel cores(8) of the rotating portion, respectively. A predetermined coil is wound around a body of the concave portion.
