Abstract
The invention discloses an outer roller axial magnetic suspension motor, which relates to a vertical type axial magnetic suspension motor or an outer roller rotating body; the motor extrudes an axial magnetic suspension bearing in a single-direction to support the weight of the roller, and is provided with a magnetic suspension ring by using a mode reversible to the structure of an inner roller to fix the axis of the motor and lead the outer side of the motor to rotate so as to become an outer roller axial magnetic suspension motor.
Description
Affiliated technical field
The present invention relates to a kind of outer roller axial magnetic suspension motor, this external rotor electric machine is that suspended ring is installed on the shell of motor, to support magnet ring is fixed on the motor shaft, motor shaft is maintained fixed, rotor can be installed on the shell like this, do the diameter that can amplify extrusion ring like this, can make suspended state highly stable.Belong to the magnetic levitation technology field.
Background technology
At present, when the big weight rotor of carrying, can only select the rolling thrust bearing for use both at home and abroad.The external rotor impeller volume of the hydraulic turbine for example, weight and diameter are all very huge, and pressure and frictional force to the rolling thrust bearing during rotation are all very big, can a large amount of kinetic energy of loss, reduce generating efficiency and service life of equipment.
Summary of the invention
Big in order to overcome rolling thrust bearing frictional force, the low and shortcoming that is easy to damage of energy utilization rate.The invention provides a kind of unidirectionally extruded magnetic suspension bearing that is used to support big weight external rotor, to replace traditional thrust bearing.
The technical scheme that problem adopted that the principle of the invention solves is: on the basis that main shaft is fixed, two or more support extrusion rings are installed on the main shaft by connector, two or more corresponding suspension magnet rings are fixed on the rotational shell of motor, also be fixed with rotor and load on the shell of motor simultaneously, for example blade.So just can make the external rotor and the load of motor be in the axial suspension state.
The outside of pushing suspended ring simultaneously can chamfering, also can open a right angle groove.
Description of drawings
Fig. 1 is the radial section structural map that the loaded article outer roller axial magnetic suspension motor is arranged of the present invention.
Among Fig. 1, fixed axis 1 is fixed on the suspension magnet ring 2 on the rotational shell, and shell and suspended ring connector 3 support extrusion ring 4, the connector 5 of extrusion ring and fixed axis, motor housing 6, motor stator 7, rotor 8, loaded article 9 etc.This motor is vertical external rotor electric machine, and after the installation, the weight of whole rotor 8 is delivered to up and down on two suspension magnet rings 2, and the magnet ring 2 that suspends this moment is relative with support ring 4 homopolarities, pushes.Support ring 4 is fixed on the motor fixing shaft 1 by connector 5.So just realized the axial magnetic suspension of all loaded articles on rotor 8 and the motor housing 6 thereof.
Wherein suspending magnet ring 2 all can chamfering with the edge that supports magnet ring 4.The shape of chamfering can be the oblique angle, can be trapezoidal, also can be that the oblique angle is in conjunction with trapezoidal.
Except that above embodiment, the present invention also has other execution modes.All employings are equal to the technical scheme of replacement, equivalent deformation formation, all drop in protection scope of the present invention.
Claims (3)
1. outer roller axial magnetic suspension motor, it is characterized in that: fixed axis 1 is fixed on the suspension magnet ring 2 on the rotational shell, shell and suspended ring connector 3, support extrusion ring 4, the connector 5 of extrusion ring and fixed axis, motor housing 6, motor stator 7, rotor 8, loaded article 9 etc.This motor is vertical external rotor electric machine, and after the installation, the weight of whole rotor 8 is delivered to up and down on two suspension magnet rings 2, and the magnet ring 2 that suspends this moment is relative with support ring 4 homopolarities, pushes.Support ring 4 is fixed on the motor fixing shaft 1 by connector 5.So just realized the axial magnetic suspension of all loaded articles on rotor 8 and the motor housing 6 thereof.
