The embodiment of the present application provides a kind of magnetic pole module 100, and magnetic pole module 100 is used to be installed on the magnetic yoke 200 of rotor
Magnet mounting surface, as shown in Figures 1 to 4, magnetic pole module 100 includes: pedestal 1 and magnet 2.Pedestal 1 include Base body 11,
And two pedestal wing plates 12, two pedestal wing plates 12 are separately positioned on the length direction two sides of Base body 11, magnet 2 is arranged
In the top surface of Base body 11.The length direction of pedestal wing plate 12 is parallel to the length direction of Base body 11, two pedestal wings
Plate 12 is respectively arranged with first boss 13 in the same end of length direction, and first boss 13 is set to the top surface of pedestal wing plate 12
On.
When by magnetic pole module 100 provided by the embodiments of the present application application in the rotor, the top surface of pedestal wing plate 12 in pedestal 1
Along the radial direction of magnetic yoke 200 and radial position limiting structure (such as press strip wing plate) face of press strip.During assembly, can in advance by
Multiple press strips are mounted on the predeterminated position of magnet mounting surface in magnetic yoke 200, and each magnetic pole module 100 is then placed in corresponding two
Between a press strip, magnetic pole module 100 is fixed in magnetic yoke 200 by the extruding of pedestal wing plate 12 using press strip.This fixation side
Formula greatly facilitates the installation and removal operation of magnetic pole module 100, helps to improve the assembly efficiency of motor, it is difficult to reduce assembly
Degree, is conducive to the maintenance and replacement in 100 later period of magnetic pole module.
For existing some motors, before the assembly for carrying out motor, magnetic yoke and magnetic pole module in rotor are separation
's.The magnet mounting surface of magnetic yoke is circumferentially arranged multiple press strips, deposits between the radial position limiting structure and magnet mounting surface of press strip
Pedestal in radial clearance, magnetic pole module includes Base body and two pedestal wing plates.When being assembled, first by magnetic yoke with
Stator is assembled together, so that magnetic yoke and stator are relatively fixed, then by the axial merging pair along magnetic yoke of each magnetic pole module
Between two press strips answered, pedestal wing plate is placed in the radial clearance between the radial position limiting structure of press strip and magnet mounting surface, makes
It obtains magnetic pole module and magnetic yoke is fixed on by press strip, to complete the assembly of motor.In the installation process of magnetic pole module, pedestal wing plate
It always happens and CONTACT WITH FRICTION and is squeezed in the radial direction of magnetic yoke with press strip, due to making the limitation of precision, pedestal wing plate and pressure
The possible out-of-flatness in the face that item contacts with each other, this may will cause the two and interfere, and factors above will lead to magnetic pole module
Easily occur excessive retardance in installation process, increases installation difficulty, influence installation effectiveness.
