Double-generator structure of integrated shell

Abstract

The invention provides a double-generator structure of an integrated shell. The double-generator structure comprises a motor shell, a first stator assembly, a first rotor assembly, a second stator assembly, a second rotor assembly, a rotor bracket, a rotary transformer and a rear end cover, the motor shell is fixedly connected with the rear end cover through a first bolt, the rear end of the rotor support is of a cylindrical structure, the first rotor assembly is fixedly arranged on the outer wall of the cylindrical structure, and the second rotor assembly is fixedly arranged on the inner wall of the cylindrical structure; according to the double-generator structure of the integrated shell, the rotor support, the inner rotor and the outer rotor form the rotor assembly, the space size of the motor is reduced, the number of parts of the scheme of the integrated rotor assembly is small, and installation is convenient; and the double rotors are simultaneously driven to generate electricity through the rotor support, the structure is simple, the rotor assemblies of the two motors are installed on the same rotor support, and only one rotary transformer is needed for rotating speed control and information feedback.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a double generator structure with an integrated casing. Background technique [0002] Although pure electric vehicles have the advantages of energy saving, environmental protection, and zero emissions, their driving range is limited. If the electric energy of the battery is exhausted before reaching the destination, the electric vehicle cannot move forward. At this time, the battery urgently needs to be supplemented with electric energy. A generator set integrated with a high-efficiency, low-emission engine and generator - a range extender, which can quickly replenish electric energy for the battery and solve the problem of short driving range of pure electric vehicles. The bottleneck problem that restricts the wide application of range extenders is the lack of high-efficiency, high-reliability, and stable output voltage generators. At present, the generators used ...
