Description
Technical field
The utility model relates to each phase magnetic circuit decoupling zero magneto of a kind of magneticfocusing, and it has higher power density, belongs to the motor manufacturing technology field.
Background technology
Magneto in the past, the tool rotor structure is not the permanent magnet arrangement that adopts magneticfocusing, can not realize each phase magnetic circuit independence decoupling zero, also not adopt the design of eccentric air gap in addition, so can not realize having the permagnetic synchronous motor of each phase winding independent sinusoidal ripple.This motor before, if it is will realize drive controlling,, not too convenient as long as adopt comparatively complicated vector control algorithm.
The utility model content
The purpose of this utility model provides each phase magnetic circuit decoupling zero magneto of a kind of magneticfocusing, makes it not only have higher power density, and realizes each phase magnetic circuit decoupling zero by the magnetic structure of uniqueness, finally realizes the speed governing requirement of wide region.
The purpose of this utility model reaches by the following technical programs.
Each phase magnetic circuit decoupling zero magneto of a kind of magneticfocusing of the present utility model, it mainly comprises armature winding, stator, rotor core, radial permanent magnet body, tangential permanent magnet body, it is characterized in that, stator is along being provided with 12 slot numbers on every side, slot number is provided with armature winding, and be three phase windings, the span of every phase coil is a groove, constitutes two couples three phase winding A-X, B-Y, C-Z; Rotor core is provided with 10 radial permanent magnet bodies and 10 tangential permanent magnet bodies, constitutes the magneticfocusing brick minor structure of composite excitation; Connect the rotor periphery place at the external end of tangential permanent magnet and be provided with air-gap.Air-gap has certain-length, and has certain ratio relation between its maximum air gap length and the minimal air gap length.
Operation principle of the present utility model and function thereof are as described below:
Two zinc-iron boron permanent magnets of tangential adjacent setting excitatory formation air-gap field in parallel.Because the principle of polar repulsion, the ferrite permanent magnet with identical polar is radially placed in the bottom, has suppressed the leakage field of bottom on the one hand, has replenished the magnetic flux in the air gap on the other hand again.Therefore adopt this mixing magneticfocusing brick minor structure, have higher air gap flux density on the one hand, also reduced the cost of motor on the other hand.The relation that has Z=P+2 between the rotor number of poles P of the type motor and the number of stator slots Z.Special slot number number cooperates that to make that the type motor has each phase mutual inductance magnetic linkage minimum, and mutual inductance is approximately zero characteristics.By selecting the ratio K of different maximum air gap length δ max and minimal air gap length δ min, can realize that back-emf is the permagnetic synchronous motor (comprising rectangular wave and sine wave) of different wave, and realize having the drive system of different salient poles than Lq/Ld.Because adopt the structure of eccentric air gap, can make the winding back emf waveform is sine wave or rectangular wave, thereby realizes the magneto of each phase magnetic circuit independence decoupling zero.Be sinusoidal wave the type motor for having counter potential waveform,, broken away from conventional with the complicated control algolithm of magnetic-synchro motor based on vector converter because each phase magnetic circuit decoupling zero because adopt simple scalar control algolithm, can realize high performance drive controlling.Can obtain different salient poles by adjusting K value in addition must ask to satisfy different speed governing occasions than the drive system of Lq/Ld.Especially bigger salient pole helps to realize the wide-range-timing system than the reluctance torque that produces.
