It sets on axis 32, the rotor is connect with the rotor 1 and the rotor inner surface and motor stator outer surface
Relatively.
Further, be provided between the inner cylinder of the rotor 1 of the axis 32 and the laser radar first bearing 34 with
Second bearing 35, to the rotation of supporting rotor 1.Specifically, the first bearing 34 is set to the rotor of the laser radar
It between pedestal 3 and the inner cylinder of the rotor 1, is connect with the axis 32, the second bearing 35 is set to the interior of the rotor 1
The top of cylinder, connect with the axis 32.In the present embodiment, rotation base is provided for the rotation of rotor 1 by driving device 33
Plinth, and by the rotation of 35 common support rotary component of first bearing 34 and second bearing, reduce rubbing in 1 motion process of rotor
Coefficient is wiped, and makes rotor 1 that can ensure its rotating accuracy with held stationary in rotation, overcomes and uses single shaft in the prior art
The rotation of support rotary component is held, causes scanning rotating speed low, the problem of stability of rotation difference so that laser ranging reaches best effect
Fruit, while sweep speed can be improved, improve the working efficiency of laser radar.Further, the upper plane of the rotor 1
Multiple first counter weight constructions 1131 are provided on 113.
As a preferred embodiment, first counter weight construction 1131 include multiple counterweight tanks and it is multiple match repeated hole, it is described
