The utility model discloses a permanent-magnetic motor rotor which belongs to the technical field of a motor and solves the problems that permanent magnets are fragile and are inconvenient to be assembled. The permanent-magnetic motor rotor comprises a cylindrical magnetic conductor (1). A rotor shaft (2) which is coaxial with the magnetic conductor is arranged on the magnetic conductor, an even number of permanent magnets (3) are uniformly arranged at the cylindrical face of the magnetic conductor along the circumferential direction, N/S poles of the permanent magnets are interlaced, the inner faces of the permanent magnets are matched with the cylindrical face of the magnetic conductor, and fixing holes (4) are arranged on the permanent magnets; holes (5) are arranged along the radial direction on the positions at the cylindrical face of the magnetic conductor correspondingly to the fixing holes on the permanent magnets, through holes (6) which are communicated with the inner ends of the holes (5) are axially arranged at the end face of the magnetic conductor, screws (7) are arranged in the fixing holes and the holes in a penetrating manner, and screw caps (8) which are screwed with the screws are arranged in the through holes. The permanent magnets are fixed on the magnetic conductor by the screws and the screw caps, so that both the assembling and disassembling are fairly convenient; when in assembling, the permanent magnets cannot be cracked due to the edges of the permanent magnets are pressed.
Description
Technical field
The utility model belongs to technical field of motors, is a kind of permanent magnet machine rotor of brushless electric machine.
Background technology
The existing permanent magnet machine rotor that is used for brushless electric machine generally comprises columniform magnetic conductor, and the face of cylinder of magnetic conductor is along circumferentially evenly being provided with the extremely staggered permanent magnet of even numbered blocks N, S, and the permanent magnet shape is the arc surface shape of matching with the face of cylinder of magnetic conductor.The mode that the mount permanent magnet is adopted be on the face of cylinder of magnetic conductor, be provided with can ccontaining permanent magnet groove, permanent magnet is placed in the groove, be stained with glue then, perhaps apply certain power again the trough rim of groove is out of shape to push down the side of permanent magnet, reach the purpose of fixed permanent magnet.This fixed form permanent magnet comes off easily, and assembling and dismounting be trouble very all, firmly beats magnetic conductor later and can produce distortion and get into smooth just not steadily, in addition, because permanent magnet is more crisp, causes the permanent magnet corner cracked easily during trough rim punching press distortion.
The utility model content
The permanent magnet machine rotor that provides a kind of permanent magnet easy to assembly is provided the purpose of this utility model.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is: permanent magnet machine rotor, comprise columniform magnetic conductor, magnetic conductor is provided with the armature spindle coaxial with it, the face of cylinder of magnetic conductor is along circumferentially evenly being provided with even numbered blocks N, the permanent magnet that S is extremely staggered, the inner face of permanent magnet cooperates with the face of cylinder of magnetic conductor, described permanent magnet is provided with fixing hole, the face of cylinder of described magnetic conductor with each piece permanent magnet on the corresponding position of fixing hole on radially be provided with the hole, the end face of magnetic conductor is provided with the through hole of intercommunicating pore the inner vertically, in fixing hole and hole, be equipped with screw, in through hole, be provided with the nut that is spirally connected with screw.
Inner face with permanent magnet during assembling is attached on the face of cylinder of magnetic conductor, and fixing hole aligns with the hole, and screw is inserted along fixing hole, hole, places nut in through hole, and the inner and the nut of screw are spirally connected, and permanent magnet can be fixed on the magnetic conductor.The utility model is fixed on permanent magnet on the magnetic conductor by screw and nut, and assembling and dismounting are all very convenient, can not produce the edge that is pressed onto permanent magnet during assembling and cause cracked phenomenon.
