Detailed description of the invention
Fig. 1 is the schematic cross-section of rotor in a kind of high power laser system of processing servo motor of the utility model.
Specific embodiment
A kind of high power laser system of processing servo motor of the utility model is described with reference to the drawings, as seen from the figure:
Embodiment 1:
This high power laser system of processing servo motor, including stator (attached to be not shown in the figure) and rotor, the stator
It is sheathed on outside the rotor, the rotor includes installation hyte and heat dissipation channel, and the installation hyte is with the axle center of the rotor
4 groups are uniformly embedded with by circumferencial direction for the center of circle, every group of installation hyte includes 3 layers of installation position, and every layer of installation position includes multiple head
The independent mounting groove 1 that tail connects；Permanent magnet is fixed in each mounting groove 1, the section of the mounting groove 1 is in strip
Shape, and match with the permanent magnet, two adjacent permanent magnet polarities are opposite；
Every layer of installation position includes 3 mounting grooves 1, and it is bracket groove 11 that every layer of mounting groove 1, which is located in the middle mounting groove 1, and two
Two mounting grooves 1 at end are side channel 12；The two neighboring bracket groove 11 is in be mutually perpendicular to, and two neighboring side channel 12 is parallel to each other.
In same installation hyte, the distance between every layer of installation position is first distance 21, and the distance between two neighboring side channel 12 is
Second distance 22, the first distance 21 are equal to second distance 22.
Multiple groups install hyte and are uniformly arranged 4 groups, and every group 3 layers of setting, every layer of 3 mounting groove 1, quantity along the circumferential direction of rotor
With medium density so that distribution of the mounting groove 1 in rotor is more regular, and parallel between two neighboring side channel 12, in two
Between slot 11 vertically, machining accuracy is quickly positioned and improves when more convenient this rotor of processing.Along with first distance 21 and
Two distances 22 are equal, permanent magnet are distributed more uniform, and the permanent magnet in four groups of installation hytes is enough on section
Form the magnetic line of force that is evenly distributed, when cooperating with stator there is no as the magnetic line of force it is uneven caused by fluctuation of service.
After permanent magnet is mounted in all mounting grooves 1, the mutual superposition of magnetic force forms powerful magnetic field, finally rotates
