Description

Double-generator structure of integrated shell

Technical Field

The utility model belongs to the technical field of generators, and particularly relates to a double-generator structure of an integrated shell.

Background

Although the pure electric vehicle has the advantages of energy conservation, environmental protection and zero emission, the driving range is limited, and the electric vehicle cannot move forward if the electric energy of the storage battery is exhausted before the pure electric vehicle reaches a destination, and the storage battery is in urgent need of supplementing the electric energy. A generator set integrating an engine and a generator with high efficiency and low emission, namely a range extender, can quickly supplement electric energy for a storage battery and solve the problem of short driving range of a pure electric vehicle. The bottleneck problem restricting the wide application of the range extender is that a generator with high efficiency, high reliability and stable output voltage is lacked, but the generator which is matched with the automobile at present generally has the defects of small output power and low generating efficiency, and can not meet the use requirements of users.

The utility model discloses a stator permanent magnet type double-mechanical-port motor for an extended range electric vehicle and a power assembly, wherein the stator permanent magnet type double-mechanical-port motor for the extended range electric vehicle comprises a generator and a driving motor, the generator is an inner rotor stator permanent magnet type inner motor formed by a motor input shaft, an inner rotor and a permanent magnet type inner stator, and the driving motor is an outer rotor stator permanent magnet type outer motor formed by a permanent magnet type outer stator, an outer rotor and a motor output shaft; it can be seen that this structure cannot drive both rotors simultaneously, and at the same time, the motion states of both rotors are difficult to detect.
