Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model that the present invention is protected
Enclose.
As shown in figure 1, the embodiment of the present invention includes：
A kind of Impeller Pumps with Active Magnetic Bearings of sewage disposal device, including rotating shaft bar 1, bearing sleeve 2, axial displacement sensing
Device 3, radial displacement transducer 4, axial magnetic bearing stator 5, stator coil 6, vane rotor magnet steel 7 and vane rotor 8, it is described
Rotating shaft bar 1 be horizontally set on the centre position of bearing sleeve 2, described shaft position sensor 3 is horizontally set on rotating shaft bar 1
Front end, described radial displacement transducer 4 is vertically set on rotating shaft bar 1 and positioned at the front end of bearing sleeve 2, described leaf
Wheel rotor magnetic steel 7 and vane rotor 8 are arranged on rotating shaft bar 1 and inside bearing sleeve 2, and described axial magnetic bearing is determined
Son 5 is respectively provided on the periphery of vane rotor 8, and described stator coil 6 is arranged on the periphery of vane rotor magnet steel 7.Wherein,
Described vane rotor magnet steel 7 is located between two vane rotors 8.
Further, described Impeller Pumps with Active Magnetic Bearings also includes radial direction magnetic bearing stator 9, described radial direction magnetic axis
Stator 9 is held to be vertically provided at respectively between axial magnetic bearing stator 5 and stator coil 6.Wherein, described radial direction magnetic bearing stator
