Description
Technical field
The present invention relates to synchronous reluctance permanent-magnet motor rotor key manufacturing technology, belong to technical field of motors.
Background technology
Synchronous reluctance permanent magnetic motors is the combination of a kind of synchronous reluctance (SR) motor and permanent-magnet synchronous (PMSM) motor.Its feature is that rotor does not have excitation winding, connects AC power and produces magnetic field, produce electromagnetic torque, thus realize energy converting between mechanical because straight, quadrature-axis reluctance there are differences by stator winding.
Synchronous reluctance permanent magnet motor primarily of stators and rotators two large divisions composition, stator and common threephase asynchronous basically identical, but its rotor magnetic circuit structural is different from other motor.The magnetic structure that rotor is different, decides runnability and the range of application of motor.The difference of rotor structure causes rotor mounting process to be also different from other motor.
Permanent-magnet synchronous motor rotor mounting process is the emphasis in permanent magnet synchronous motor mounting process, for built-in permanent-magnet synchronous motor and surface type permanent magnet synchronous motor rotor mounting process, in various document, patent, all has introduction.
Built-in permanent-magnet synchronous motor has cast aluminium to start cage, can cast aluminium cage fixed rotor in cast aluminium process, finally prevents interior permanent magnets play with rotor stop plate, then uses stud fixed rotor baffle plate.
Surface type permanent magnet synchronous motor utilizes stud fixed rotor, and permanent magnet is pasted on rotor surface.
But synchronous reluctance permanent-magnet motor rotor complex structure is different from built-in, surface type permanent magnet synchronous motor, this motor does not start cage, cannot with starting cage fixed rotor, and use stud fixed rotor, then rotor stop plate and permanent magnet are installed and certainly will be become contradiction, namely first rotor stop plate is installed, then permanent magnet cannot put into rotor, if first use stud fixed rotor, then permanent magnet is put into, finally at installation rotor stop plate, then stud fixed rotor baffle plate cannot be used, need other device fixed rotor baffle plate, increase difficulty of processing, therefore, current synchronous reluctance permanent-magnet motor rotor technique is seldom mentioned.
The rotor installation method that the patent No. 201210056283.2 title " installation method of permanent magnetism assist in synchronization magnetic resistance motor rotor and motor and motor " proposes, only propose the baffle plate capping of rotor core two ends, thus permanent magnet is fixed in mounting groove.
The patent No. 201210056090.7 title " assemble method of permanent magnetism assist in synchronization reluctance motor and rotor and this motor " propose by the baffle plate capping of rotor core two ends, thus permanent magnet to be fixed in permanent magnet trough.
Above-mentioned two patents only propose to use baffle plate capping, but propose rotor core how to press-fit for entirety, and do not consider rotor press-mounting and permanent magnet assemble between relation.
Summary of the invention
The technical problem to be solved in the present invention is: it is large that the permanent magnet assembling of synchronous reluctance permanent magnet motor and rotor punching laminate difficulty.
In order to solve the problems of the technologies described above, technical scheme of the present invention there is provided a kind of synchronous reluctance permanent-magnet motor rotor key manufacturing technology, it is characterized in that, comprises the steps:
The first step, the false permanent magnet bar of closing with the matching form of at least one permanent magnet trough on rotor punching to be laminated to be fixed, subsequently by put in order the rotor punching that needs to be laminated to penetrate in axle and to insert false permanent magnet bar, during insertion, false permanent magnet bar is made to insert the permanent magnet trough be mated;
Second step, adopt dismountable hold-down mechanism that the stacked good rotor punching obtained by the first step is compacted into rotor core, ensure the length that rotor core reaches identical with stator core;
3rd step, false permanent magnet bar to be taken out, in each permanent magnet trough, put into permanent magnet blocks;
4th step, lay rotor stop plate jaggy respectively in the both sides of rotor core, the gap position on rotor stop plate avoids the position of hold-down mechanism, interior fastening bolt is inserted the through hole in rotor core, and fixes with interior clamp nut;
5th step, unclamp interior clamp nut after, hold-down mechanism is disassembled, again fastening interior clamp nut, ensures the length that rotor core reaches identical with stator core.
Preferably, described hold-down mechanism comprises pressing plate, and outer fastening bolt is locked by outer clamp nut through two ends after pressing plate, and stacked good rotor punching is compressed by pressing plate.
Preferably, described rotor core is formed with multiple permanent magnet trough region, between every two adjacent permanent magnets groove region, is furnished with a described hold-down mechanism.
