Abstract
The utility model relates to a permanently magnetic disk motor with axial magnetic flux, in particular to a disk motor without a rotor yoke and a stator yoke. The disk motor comprises a pair of rotor disks and a stator located between the two rotor disks, and permanent magnets arrayed on the circumference are fixedly mounted on the inner surface of the rotor disks. The rotor disks are made of non-magnet-conductive materials. The permanent magnets include two types including perpendicular-pole permanent magnets with directions of poles perpendicular to disk faces of the rotor disks and parallel-pole permanent magnets with directions of poles parallel to the disk faces of the rotor disks. The perpendicular-pole permanent magnets and the parallel-pole permanent magnets are distributed on the circumference in a stagger manner. In addition, directions of the poles of each two adjacent perpendicular-pole permanent magnets are opposite, and directions of the poles of each two adjacent parallel-pole permanent magnets are also opposite. Magnetic loss on rotors is reduced, magnetic properties of the permanent magnets are utilized fully, magnetic leakage is reduced, and power density of the motor is increased.
Description
Technical field
The utility model relates to the permanent magnet disc motor with axial magnetic flux, specifically is a kind of disc type electric machine that does not have rotor iron yoke and stator iron yoke.
Background technology
At present, have that the desk permanent-magnet motor of axial magnetic circuit of outer-rotor structure of two p-m rotors, a stator comparatively more sees that the p-m rotor of this motor has two; Place the both sides of stator discs respectively, it is discoid that stator core adopts silicon steel sheet to be wound into, and fluting is placed coil on two end faces of disk respectively; Simple in structure, efficient advantages of higher that this motor has; But the yoke portion head of stator core has occupied more volume and weight, and can produce yoke portion magnetic loss; In order further to improve electric efficiency, stator can adopt the structure of no iron core, and promptly stator coil adopts the macromolecular material casting to form.Though this motor has reduced the core loss of stator; But because stator is an air core coil, the actual air gap of motor is bigger, thereby the leakage field in magnetic field is also bigger; Cause the magnetic property of permanent magnet to be not fully utilized, and the eddy current loss of air core coil is also bigger; In addition, this type of rotor must adopt yoke, as permanent magnet the magnetic circuit passage is provided, and will on rotor, produce magnetic loss like this; In addition, because stator component is clipped in the middle of two rotor disks, the film-cooled heat of motor reduces greatly, is unfavorable for being designed to heavy-duty motor.
Summary of the invention
The utility model technical problem to be solved is; Provide that a kind of motor flux leakage is little, heat-sinking capability is strong, little, the no stator and rotor iron of coil eddy current loss yoke; The power density of motor can be improved effectively, the no rotor iron yoke of the high efficiency of motor, high-power design and the disc type electric machine of stator iron yoke can be realized.
The no rotor iron yoke of the utility model and the disc type electric machine of stator iron yoke include a pair of can be around machine shaft rotor rotated dish and the stator between two rotor disks, each rotor disk inner surface is installed with the permanent magnet along circumferential arrangement; Said rotor disk is processed by non-magnet material; Said permanent magnet is divided into two kinds, and a kind of is the pole orientation vertical pole permanent magnet vertical with the card of rotor disk, and another kind is the pole orientation parallel magnetic pole permanent magnet parallel with the card of rotor disk; Said vertical pole permanent magnet is arranged along circumference is staggered with parallel magnetic pole permanent magnet, between promptly per two adjacent vertical pole permanent magnets a parallel magnetic pole permanent magnet is arranged, and a vertical pole permanent magnet is also arranged between per two adjacent parallel magnetic pole permanent magnets; And the pole orientation of per two adjacent vertical pole permanent magnets is opposite, and the pole orientation of per two adjacent parallel magnetic pole permanent magnets is also opposite.
Said stator includes a plurality of solenoids that are uniformly distributed along the circumference; The cross section of solenoid is a rectangle; The stator core of solenoid is axially placed in the inner chamber of solenoid, and each group solenoid and iron core are installed on the inner walls cylindraceous through cross-under bolt radially.
Said stator core is formed by the silicon steel plate stacking of " worker " font, and said cross-under bolt carries out cross-under to silicon steel sheet simultaneously and connects.
Adopt after the above technical scheme, the epitrochanterian permanent magnet of motor is owing to adopted the distribution mode of HALBACH array, and rotor disk can adopt the backboard of non-magnetic material as magnet, thereby has reduced the magnetic loss on the rotor iron yoke; In addition, owing to added permeability magnetic material such as silicon steel sheet in the stator coil, the effective air gap of motor shortens greatly, and the magnetic property of permanent magnet is fully used, and leakage field reduces, and the power density of motor is improved.And through adopting above technology, the axial length of motor stator has obtained appropriate increase, and the heat-sinking capability of motor has obtained reinforcement.
