Abstract

The invention discloses an exhaust gas turbine-driven reluctance motor, which belongs to the field of vehicle engineering. The exhaust gas turbine-driven reluctance motor comprises a shaft, a first armature core, a rotor core, a first armature coil, a second armature core, a second armature coil and the like, and is characterized in that the first armature core and the second armature core are symmetrically located at two axial sides of the rotor core and are fixed on a motor shell; 4k fan-shaped through holes are uniformly distributed in the circumference of the rotor core, and k is a positive integer larger than 1; one side, facing the rotor core, of each of the first armature core and the second armature core is provided with 5k fan-shaped convex armature pole, and the armature poles are wound with integrated armature coils. The rotor core has a small moment of inertia and quick response; and poles of the stator and the rotor are few, high-speed rotation can be realized, and the reluctance motor is extremely suitable as a motor driven by the exhaust gas turbine.

Description

technical field [0001] The invention relates to a reluctance motor driven by an exhaust gas turbine and belongs to the field of vehicle engineering. Background technique [0002] At present, 25% to 40% of the total energy of fuel combustion in the cylinder of the automobile engine is converted into effective work, and the remaining 60% to 75% are lost, of which 25% to 35% is taken away by waste energy. Waste energy recovery has Practical significance. Most automobile alternators are alternators driven by pulleys, and the efficiency of the alternator is about 50%. Therefore, the total efficiency of the engine driving the generator to generate electricity is only about 17.5%. This is far less than the power generation efficiency of a turbo generator. Therefore, using the exhaust gas discharged from the engine to directly drive the generator to generate electricity can effectively utilize the characteristics of high power generation efficiency of the turbogenerator and impro...
