Wheel permanent-magnet generator

Abstract

The invention discloses a wheel permanent-magnet generator which comprises a wheel and a permanent-magnet generator, wherein the wheel is a driven wheel and comprises an axle, a wheel shell and a wheel shell cover plate; the permanent-magnet generator mainly comprises an outer rotor and an inner stator, wherein the inner stator is fixed on the axle between the wheel shell and the wheel shell cover plate; the outer rotor corresponds to the inner stator and is placed on the inner wall of the wheel shell; and a power supply output wire of a winding coil on the inner stator is connected with external electricity-storage equipment after penetrating through the axle. The stator is connected with the axle through a stator bracket; a bearing is arranged among the wheel shell, a wheel cover and a shaft, and an oil seal is arranged at the outer side; and rare-earth permanent-magnet steel is arranged on the inner wall of the outer rotor. The wheel permanent-magnet generator adopting the structure not only has the advantages of simple and compact structure, less loss, environmental protection, scientificity and quite reliable operation and is used on the driven wheels of various vehicles, such as automobiles, electric vehicles or hybrid vehicles, and the like, and the outer rotor on the wheel permanent-magnet generator is driven to rotate by the wheel to generate electrical energy. The wheel permanent-magnet generator is an ideal vehicle-mounted electricity generating device.

Description

technical field [0001] The invention relates to a generator, in particular to an automobile, electric vehicle or hybrid wheel generator. Background technique [0002] At present, the generators widely used in practice are mainly permanent magnet generators and excitation generators. The biggest difference between permanent magnet generators and excitation generators is that their excitation magnetic field is generated by permanent magnets. The permanent magnet in the permanent magnet generator is both a magnetic source and a component of the magnetic circuit in the generator. The permanent magnet generator eliminates the excitation winding, carbon brush and slip ring structure of the excitation generator, and the structure of the whole machine is simple, avoiding the easy burning and disconnection of the excitation winding, carbon brush and slip ring structure, and the structure of the whole machine is simple, It avoids failures such as easy burnout and disconnection of the...

AI Technical Summary

Problems solved by technology

However, the permanent magnet generator with this structure must be driven by external energy, such as wind, water, electric energy, etc.; and because the permanent magnet motor lacks the necessary protection device, it can only be used fixedly and cannot be used in vehicles, such as automobiles or hybrid car
