The invention discloses a rotor and an assembling method thereof, a magnetic pole module and a motor. The rotor comprises a magnet yoke, wherein the inner peripheral surface or the outer peripheral surface of the magnet yoke is a magnetic pole mounting surface; a magnetic pole module; a first axial limiting piece which abuts against the first end of the magnetic pole module in the axial direction of the rotor; and a second axial limiting piece which abuts against the second end of the magnetic pole module in the axial direction, wherein at least one of the first axial limiting piece and the second axial limiting piece is detachably connected with the magnet yoke. According to the rotor provided by the embodiment of the invention, the magnetic pole module can be assembled or disassembled through the at least one axial end of the magnet yoke, so that the assembly of the rotor or the disassembly and replacement of the magnetic pole module are facilitated. The first axial limiting piece and the second axial limiting piece can be prefabricated and formed and are easy to machine, and compared with the technical scheme that a groove structure is machined on the magnet yoke to limit the magnetic pole module, the method is more efficient, and cost is saved.
Description
technical field [0001] The invention relates to the field of motors, in particular to a rotor and an assembly method thereof, a magnetic pole module and a motor. Background technique [0002] In a permanent magnet motor, the stator and the rotor are important components of the motor. The stator is the fixed part of the motor, and the rotor is the rotating part of the motor. The two can rotate relative to each other. [0003] In the prior art, when the rotor is assembled, the magnetic pole module is generally fixed in the axial direction of the rotor, which requires machining the groove structure in the axial direction on the yoke of the rotor bracket, and then the magnetic pole module is placed In the groove structure to realize the limit of the magnetic pole module. In the above-mentioned assembly process, the processing groove structure increases the processing cost of the rotor, and the processing process consumes a lot of man-hours, and there are beading bars between ad...
