Abstract
A magnetic suspension bearing motor relates to a frequency control motor. The utility model discloses a technique which comprises a motor consisting of a rotating shaft 1 with an iron core, a front end cover 2, a back end cover 3 and magnetic suspension bearings 4. One magnetic suspension bearing 4 is embedded in an annular groove in the internal end face of the front end cover 2, the other magnetic suspension bearing 4 is embedded in an annular groove in the internal end face of the back end cover 3, the back end of the rotating shaft of the motor is inserted into the magnetic suspension bearing 4 assembled on the back end cover, and the front end of the rotating shaft of the motor passes through the magnetic suspension bearing 4 assembled on the front end cover and the axial hole of the front end cover 2. Compared with a rolling bearing and a sliding bearing, the magnetic suspension bearing motor has the advantages of simple and compact structure, convenient manufacture and assembly, high speed, high precision, low power consumption, long service life, etc. The air suspension bearing motor also improves the speed of the bearing by 10-30 times, improves the bearing precision by 2 orders of magnitude, reduces the power consumption by (0.2 percent), and improves the service life of the bearing by dozens of times. In addition, the magnetic suspension bearing motor avoids the lubricating forbidden zone of a conventional bearing.
Description
One, technical field
The utility model relates to frequency control motor, especially a kind of magnetic suspension bearing motor of frequency control.
Two, background technology
During the frequency control motor operation, particularly heavy-duty motor has the high characteristics of rotating speed, during the pot motor operation, adopt that conventional rolling bearing and sliding bearing have that vibration is big, noise is high, frictional dissipation is big (2%), temperature rise, oil (oil gas mist) lubrication and seal be difficult to resolve certainly defectives such as environmental pollution major defect.
Three, summary of the invention
The purpose of this utility model provide a kind of simple in structure, easy to maintenance, operating cost is low, it is little to need not to lubricate, vibrate, noise is low, temperature rise is low, the magnetic suspension bearing motor of no mechanical frictional dissipation.
Technical scheme that the purpose of this utility model adopts is, include motor and have rotating shaft unshakable in one's determination, front end housing, rear end cap, magnetic suspension bearing composition, its front end housing inner face cannelure is embedded with magnetic suspension bearing, rear end cap inner face cannelure is embedded with magnetic suspension bearing, and the magnetic suspension bearing of the rear end insertion rear end cap dress of machine shaft axle is interior, front end passes the magnetic suspension bearing of front end housing dress and the axis hole of front end housing.
The utlity model has simple and compact for structurely, make easy to assemblyly, compare, have speed height, precision height, low in energy consumption, advantage such as the life-span is long with rolling bearing and sliding bearing.It makes bearing speed improve 10-30 doubly, and the supporting precision improves 2 orders of magnitude, and (2%) low in energy consumption, and the working life of bearing has increased tens of times, simultaneously, has avoided the lubricated forbidden zone of conventional bearing.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model sectional structure schematic diagram.
Among the figure: 1-machine shaft 2-front end housing 3-rear end cap 4-magnetic suspension bearing
Five, embodiment
As shown in drawings, include motor and have rotating shaft 1 unshakable in one's determination, front end housing 2, rear end cap 3, magnetic suspension bearing 4 compositions, its front end housing 2 inner face cannelures are embedded with magnetic suspension bearing 4, rear end cap 3 inner face cannelures are embedded with magnetic suspension bearing 4, and the rear end of machine shaft axle is inserted in the magnetic suspension bearing 4 of rear end cap dress, front end passes the magnetic suspension bearing 4 of front end housing dress and the axis hole of front end housing 2.
Operational mode of the present utility model is: after the magnetic suspension winding energising that is installed in the variable-frequency motor two ends, the electromagnetic force of generation pass through put big sensor control and earlier rotor be suspended in magnetic suspension coil central authorities, again frequency control motor energising operation.
Claims (1)
1. magnetic suspension bearing motor, include motor and have rotating shaft (1) unshakable in one's determination, front end housing (2), rear end cap (3), magnetic suspension bearing (4) composition, it is characterized in that front end housing (2) inner face cannelure is embedded with magnetic suspension bearing (4), rear end cap (3) inner face cannelure is embedded with magnetic suspension bearing (4), and the magnetic suspension bearing (4) of the rear end insertion rear end cap dress of machine shaft axle is interior, front end passes the magnetic suspension bearing (4) of front end housing dress and the axis hole of front end housing (2).
