Abstract

An exhaust gas turbine-driven electric excitation generator of the present invention is composed of a shaft, an exhaust gas turbine, an exhaust gas turbine shell, two sets of excitation windings, two stator cores, two sets of armature windings, a rotor core and a motor shell. An exhaust gas turbine and a rotor core are respectively fixed on the shaft, and there are rotor poles protruding axially on the two end faces of the rotor core. The stator core is fixed on the inner wall of the casing; the end face of the stator core facing the rotor core has axially protruding stator poles. The armature windings are wound around the stator poles. The excitation winding is wound around the radial direction of the stator core and embedded in the magnetic isolation groove of the stator core. The technical rotor of the present invention is manufactured in one piece and has no excitation winding, which can adapt to the high temperature and high speed working environment of the exhaust gas turbine; it adopts electrified coil excitation, has no positioning torque, and can accelerate rapidly; both ends of the rotor have armatures Winding, the motor has high specific power.

Description

technical field [0001] The invention relates to an electric excitation generator driven by an exhaust gas turbine, which belongs to the technical field of automobile electric appliances. Background technique [0002] At present, thermal power generation uses turbogenerator technology, and the total efficiency of turbogenerators for high-efficiency power generation can be increased to more than 60%-70%. [0003] At present, the thermal efficiency of the engine is mostly below 35%, and the high-temperature and high-pressure exhaust gas discharged by the engine takes away 40% of the thermal energy of the fuel, and most engines cannot effectively use this energy. The exhaust gas turbocharging device realizes the utilization of part of the kinetic energy of the exhaust gas, improves the fuel utilization rate of the engine, and is currently being used more and more widely. [0004] At present, automobile generators are mostly AC generators driven by pulleys, and the power generat...
