Abstract
The invention provides an engine exhaust-gas turbine drive permanent magnet generator, belonging to the technical field of automobile motors and electric appliances. The engine exhaust-gas turbine drive permanent magnet generator comprises a waste-gas turbine, permanent magnets, power generation systems, a rotor, a front end cover and a rear end cover, wherein the number of the permanent magnets is equal to that of the power generation systems; a group of permanent magnets and power generation systems are fixed on the same circumference in an inner cavity of the rear end cover; another group of permanent magnets and power generation systems are fixed on the same circumference in an inner cavity of the front end cover; the rotor is in a flange plate structure and is not provided with an electro-magnetic winding nor a permanent magnet. The engine exhaust-gas turbine drive permanent magnet generator is simple in structure and small in rotation inertia; an excitation magnetic field is supplied by the permanent magnets; as no electro-magnetic winding is required, the electric energy consumption is low; as no carbon brush slip ring structure is needed, the fault rate is low; as the turbine is fixed on the front end cover of the generator through bolts, the engine exhaust-gas turbine drive permanent magnet generator is compact in structure and convenient to install and is directly driven by waste gas exhausted from the engine, thus saving energy sources and reducing the loss.
