Below in conjunction with the accompanying drawings and specific embodiment is described in detail to this utility model：
A kind of high-speed and energy-saving traction machine as depicted in figs. 1 and 2, the traction machine includes main shaft 1, stator module 2, rotor
3 and frame 6, the stator module 2 is fixedly mounted in frame 6, and the left end of the main shaft 1 is matched by bearing with stator module 2
Fixed installation is closed, the right-hand member of the main shaft 1 is connected to traction sheave 5 by card key fixed cover, and 3 points of the rotor is internal rotor 31 and turns outward
Son 32, and the left end of the rotor 3 extend into inside stator module 2, and the right-hand member of the rotor 3 is fixedly connected with traction sheave 5, described
Stator module 2 is internally provided with the baffle plate 21 for internal rotor 31 and outer rotor 32 to be separated, the internal rotor 31 and baffle plate 21
Between be provided with external stator coil 22, inner stator coil 23, the stator pack are provided between the outer rotor 32 and baffle plate 21
Brake 7 and rosette 8 are additionally provided with part 2.
Its specific works mode is：
External stator coil 22 and inner stator coil 23 are installed, the power of inner stator coil 23 is little, external stator line on stator module 2
Enclose 22 power big；Internal rotor 31 is with outer rotor 32 on same rotor 3.Rotor 3 adopts supported at three point, encoder 9 and main shaft 1
It is connected, for feeding back traction machine rotating speed and the anglec of rotation.When traction machine inner stator coil 23 cannot work, external stator coil
22 replacement inner stator coils 23 work, and vice versa, and the traction machine security performance is greatly improved, and is provided with external rescue device
4, when traction machine cannot operate, using external rescue device 4 brake traction sheave, make lift car reach flat bed, car with it is right
The ratio a of LOAD CELLS, apparatus for controlling elevator intelligence computation car and counterweight is installed in weight.
The high-speed and energy-saving traction machine drive manner：
Work as a<1, car is descending or a>1, when car is up, internal rotor 31 and outer rotor 32 drive simultaneously；
As a=1, external stator 32 drives；
Work as a<1, car is up or a>1, it is generating state when car is descending, internal rotor 31 and outer rotor 32 generate electricity simultaneously
The quantity that brake 7 is arranged on the stator module 2 is three, and three brakes 7 are separately positioned on stator module 2
Both sides and tip position, two side brakes 7 are first group, and top brake 71 is braked respectively for second group；Traction machine is normal
