Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the switched reluctance machines of a kind of dual-rotor structure of the present invention, comprise casing 1, output shaft 2, power shaft 3 and slip ring 4, described casing 1 inside is provided with main shaft 5, described main shaft 5 upper surface is connected with internal rotor 6 in turn, upper external rotor 7 and upper stator 8, described upper stator 8 is connected with casing 1, described main shaft 5 lower surface is connected with lower internal rotor 9 in turn, lower external rotor 10 and lower stator 11, described power shaft 3 is connected with lower internal rotor 9 with upper internal rotor 6 respectively, described output shaft 2 is connected with lower external rotor 10 with upper external rotor 7 respectively, unofficial biography 12 is provided with between described upper external rotor 7 and upper stator 8, lower unofficial biography 13 is provided with between described lower external rotor 10 and lower stator 11, some brushes 14 are connected with outside described power shaft 3, the other end of described brush 14 connects with slip ring 4, described power shaft 3 is provided with some master references 15 with the junction of casing 1, described output shaft 2 is provided with some secondary transducers 16 with the junction of casing 1.
On above-described embodiment preferably, described casing 1 entirety is symmetrical about main shaft 5.
On above-described embodiment preferably, described upper stator 8 is identical with lower stator 11, and described upper external rotor 7 is identical with lower external rotor 10, and described upper internal rotor 6 is identical with lower internal rotor 9.

The present invention is at switched reluctance double-rotor machine both sides increase front end housing and rear end housing, because the slip ring of motor and transducer are exposed to outside, when motor runs, easily bring Danger Electric shock risk, before and after front end housing and rear end housing are screwed in, on end cap, for convenience detach, and make motor seem more attractive in appearance from appearance.
The present invention increases spring bearing at unofficial biography and external rotor junction, and mainly for ensureing the concentricity of two rotors, and inside and outside air gap is even.Because inner and outer rotors not only wants output speed also to want Driving Torque, and two axles are longer, end connects can not only lean on a point, like that when motor runs, input shaft run-out can be amplified at output shaft and its meet, here bearing will be subject to larger radial compression, easily fluctuates.If install two bearings, and keep certain axial distance between two bearings, alleviate bearing burden by increase bearing number and lever principle, strengthen the reliability of birotor parts.
Stator boss ratio of the present invention is on the impact of double-rotor machine performance: motor is when carrying out power conversion, and energy is all undertaken transmitting by the air gap between rotor with the form of electromagnetic energy, and power corresponding is with it called electromagnetic power.Key dimension and the electromagnetic power of motor have substantial connection, for double-rotor machine, have two electromagnetic powers, have certain contact between them, and the stator boss ratio of the outer motor of existing investigation is on the impact of its electromagnetic power.
Birotor switched reluctance machines of the present invention can realize the flexible transformation of speed, torque, make the engine of automobile can be operated in peak efficiency district under all form conditions, therefore the fuel economy of automobile can be significantly improved, effectively reduce discharge, the best power performance requirement of automobile can also be met simultaneously.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
