Centre bore and motor shaft key connection；Described rotating disk is located at outside fixed disk, and the cylindrical and fixed disk inner circle of rotating disk, which is formed, to be turned
Dynamic friction pair, rotating disk and fixed disk are made by high-abrasive material；Described rotating disk periphery matches with silicon steel sheet inner headed face
Close, rotating disk is synchronized with the movement with silicon steel sheet；Described silicon steel sheet periphery is provided with the magnetic shoe mounting groove of even number axial direction, magnetic shoe
Mounting groove is circumferential equiangularly arranged centered on the axis of silicon steel sheet；The magnetic shoe of opposed polarity is arranged on magnetic shoe spaced reciprocally pacifies
In tankage；
Further, the periphery of described fixed disk is provided with positioning step one, and the inner headed face of rotating disk is provided with determining
The positioning step two that position step one is engaged；
Further, the cylindrical of described rotating disk is provided with several positioning boss, on silicon steel sheet inner headed face with positioning
The corresponding position of boss is provided with the groove being engaged with positioning boss, rotating disk and the embedded mating connection of silicon steel sheet；
Further, described magnetic shoe mounting groove is the dovetail groove being engaged with magnetic shoe.
Pivoting friction pair is formed between rotating disk of the present utility model and fixed disk so that during load change, rotating disk energy
The magnetic shoe on silicon steel sheet and silicon steel sheet outside it is enough driven to be rotated relative to motor shaft so that motor rotates rotor and fixed rotor
Magnetic flux change and realize the automatic torque-changing speed governing of motor.Set between silicon steel sheet and motor shaft and be made up of high-abrasive material
Rotating disk and fixed disk, avoid between silicon steel sheet and motor shaft and directly to form friction pair, improve silicon steel sheet uses the longevity
Life, reduce the cost of maintenance.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of permanent magnet machine rotor rotating mechanism, including silicon steel sheet 1, rotating disk 2, fixed disk 3
With magnetic shoe 4, described silicon steel sheet 1, rotating disk 2 and fixed disk 3 and motor shaft are coaxial, and fixed disk 3 passes through centre bore and motor shaft
Key connection；Described rotating disk 2 is located at outside fixed disk 3, and the inner circle of cylindrical and fixed disk 3 of rotating disk 2 forms pivoting friction pair, rotation
Rotating disk 2 and fixed disk 3 are made by high-abrasive material；The described periphery of rotating disk 2 is engaged with the inner headed face of silicon steel sheet 1, rotation
Disk 2 is synchronized with the movement with silicon steel sheet 1；The described periphery of silicon steel sheet 1 is provided with the magnetic shoe mounting groove of even number axial direction, magnetic shoe installation
Groove is circumferential equiangularly arranged centered on the axis of silicon steel sheet 1；The magnetic shoe 4 of opposed polarity is arranged on magnetic shoe and installed spaced reciprocally
In groove.In practical application, this rotating mechanism is preferably used in pairs, and fastening is attached by the rivet hole on silicon steel sheet 1, can
The intensity of rotating mechanism is improved, and can is mutually located, and ensures the performance of motor.
The periphery of described fixed disk 3 is provided with positioning step 1, and the inner headed face of rotating disk 2 is provided with and positioning step
One 32 positioning steps 2 22 being engaged, location and installation is carried out with positioning step, both facilitates installation, and can plays axially position
