Generator terminal lid be connected, the interconnecting piece of the second magnet ring of first bearing is connected with machine shaft, the first magnet ring upper inner ring face place side and
The magnetic pole of side is identical where outer ring surface on second magnet ring, and inside and outside anchor ring is circular conical surface, and inner ring surface is neighbouring and opposite with outer ring surface
Arrangement.
Compared with prior art, technical effect of the invention are as follows: the repulsive force that the second magnet ring is subject to perpendicular to its outer ring surface,
The repulsive force is decomposed into axial force and radial force, and radial force makes the second magnet ring suspend, and axial force can constrain and the second magnet ring
The axial position of connected shaft reduces the axial movement value for the shaft being connected with the second magnet ring, improves the stabilization of motor operating
Property.

Specific embodiment
A kind of electromagnetic levitation type motor, arranged for interval has the first and second bearing 10,20 on machine shaft 31, and first bearing 10 is wrapped
The first and second magnet ring 11,12 of same core arrangement is included, the interconnecting piece of the first magnet ring 11 of first bearing 10 is connected with electric motor end cap 32,
The interconnecting piece of second magnet ring 12 of first bearing 10 is connected with machine shaft 51,11 upper inner ring face of the first magnet ring, 111 place side with
The magnetic pole of 121 place side of outer ring surface is identical on second magnet ring 12, and inside and outside anchor ring 111,121 is circular conical surface, inner ring surface 111 with
Outer ring surface 121 is neighbouring and positioned opposite.
As shown in fig.1, setting suspension permanent magnetic bearing, the first magnet ring 11 for the first bearing 10 on machine shaft 51
Inner ring surface 111 and the outer ring surface 121 of the second magnet ring 12 be circular conical surface, the repulsive force that the second magnet ring 12 is subject to is perpendicular to outside it
Anchor ring 121, the repulsive force are decomposed into axial force and radial force, and radial force makes the second magnet ring 12 suspend, and axial force can constrain
The axial position for the shaft being connected with the second magnet ring 12 reduces the axial movement value for the shaft being connected with the second magnet ring 12, improves
The stability of electromagnetic levitation type motor operating.
There are two types of arrangements for second bearing 20 on machine shaft 51, specific as follows:
One is as shown in Fig. 2, the interconnecting piece of the first magnet ring 11 of the second bearing 20 is connected with electric motor end cap 32,
The interconnecting piece of second magnet ring 12 of second bearing 20 is connected with machine shaft 31.I.e. the first and second bearing 10,20 is floated
Bearing, the first and second bearing 10,20 further increases the working efficiency of motor, and electricity without mechanical friction when shaft 31 works
The maximum (top) speed of machine can be increased dramatically.
The second is setting roller bearing for second bearing 20, the inside and outside circle of second bearing 20 is fitted in motor respectively and turns
In mounting hole in the middle part of axis 31, electric motor end cap 32, the stability of stability will be substantially improved when shaft 31 operates.
It is below the specific mounting means of the first and second magnet ring 11,12, the interconnecting piece of the first magnet ring 11 is the first ring set 13,
The annular groove for the first magnet ring 10 arrangement is offered on the inner wall of first ring set 13, the outer wall of the first ring set 13 radially stretches convex
