Description
Technical Field
The invention relates to an axial magnetic flux stator core made of a composite material, and belongs to the field of stator structural design.
Background
With the arrival of energy crisis, the motor demand for energy conservation and high efficiency is more urgent. Compared with the traditional silicon steel material, the amorphous alloy material has the characteristics of thin thickness, high resistivity and high relative magnetic permeability. When the amorphous material is the strip material prepared initially, the loss is only 1/5-1/8 of that of the traditional silicon steel material, so that the efficiency of the motor can be obviously increased after the amorphous material is applied to the manufacturing of the motor stator core, and the energy-saving effect is achieved. However, the amorphous alloy material is significantly affected by stress, and particularly, the crystallization of the amorphous material can be caused by adopting processes such as laser cutting, electric spark cutting or water jet cutting, so that the advantage of low iron loss of the amorphous material after being manufactured into a stator core is greatly weakened.
The soft magnetic material is formed by pressing metal powder particles with insulation on the surface, and a proper mold is designed to press the soft magnetic material, so that a richer topological structure than that of the traditional silicon steel material can be achieved. However, compared with silicon steel materials, the soft magnetic material has low saturation magnetic density, low magnetic permeability and large hysteresis loss, so that the proportion of the soft magnetic material used for designing the low-iron-loss stator core is not too large.
Currently, related patents directed to axial flux stator cores can be categorized into the following categories: 1. a method of fixing a segmented stator core (refer to chinese patent application number CN 202010953641.4); 2. a method for manufacturing a stator core of a segmented armature axial flux motor (refer to chinese patent application number CN 202010836068.9); 3. a water cooling structure of an axial flux motor stator core (refer to chinese patent application number CN 201710971588.9); none of the above patents mention an axial flux stator core made of amorphous alloy, soft magnetic material and silicon steel material.
An axial magnetic field motor, a stator structure and a stator core structure of the axial magnetic field motor, and a Chinese patent application No. CN202010953641.4, which are the most similar to the invention, introduce a modularized manufacturing and assembling method of the axial magnetic flux motor, wherein amorphous alloy, soft magnetic material and silicon steel material are not adopted to manufacture the stator core, and the modularized manufacturing method of the axial magnetic field motor is different from the above patent.

The technical scheme of the invention is as follows:
an axial magnetic flux stator core made of composite materials mainly comprises a stator yoke part 1, a plurality of split components and a plurality of magnetic slot wedges 5; each split component comprises a magnetic conduction connecting body 2, a magnetic conduction clamping core 3 and a magnetic conduction inner core 4, wherein the magnetic conduction clamping core 3 is arranged at the inner side of the magnetic conduction connecting body 2, and the magnetic conduction connecting body 2 is arranged at the inner side of the magnetic conduction clamping core 3; the lower end of the magnetic conductive connecting body 2 is provided with a fixed slot wedge 7 protruding outwards, and slot wedge holes 8 are arranged at positions, close to the upper end, of two sides of the magnetic conductive connecting body 2; the upper ends of the adjacent split members are connected by pushing the magnetic slot wedges 5 into slot wedge holes 8 of the adjacent magnetic conductive connecting bodies 2;

Preferably, the stator yoke 1 is formed by stacking multiple layers of silicon steel sheets into a cylindrical structure along the axial direction, and after the stator yoke 1 is subjected to annealing, vacuum paint dipping and curing, laser cutting, electric spark cutting or water jet cutting is performed above the cylindrical structure to machine a plurality of inwards concave slots 6.
Preferably, the magnetically conductive connector 2 is made of a soft magnetic material by pressing.
Preferably, the upper part of the magnetic conductive connector 2 is a deep groove structure, and the magnetic conductive sandwich 3 and the magnetic conductive inner core 4 are arranged inside the deep groove structure.
Preferably, the magnetic conductive sandwich 3 is in a cylindrical structure.
Preferably, the magnetic conductive sandwich 3 is formed by winding an amorphous alloy strip along the magnetic conductive inner core 4, laminating tightly, annealing, impregnating, shaping and solidifying.
Preferably, the magnetic conductive inner core 4 is formed by axially laminating a plurality of layers of silicon steel sheets, and then annealing, paint dipping, shaping and curing.
Optionally, the magnetically conductive inner core 4 is formed by pressing a soft magnetic material.
Preferably, the magnetic slot wedge 5 is a strip with two protruding ends and magnetic conductivity, and the protruding shape and the concave shape of the adjacent magnetic conductive connector 2 form an assembly matching relationship.
When in assembly, the lower parts of the magnetic conduction sandwich 3 and the magnetic conduction inner core 4 are coated with adhesive, and the adhesive is adhered to the inside of the deep groove structure of the magnetic conduction connector 2, so as to manufacture the split component; the split component is put into a winding machine for winding, so that a part below the slot wedge hole 8 of the magnetic conductive connector 2 is wound with a winding 9 with proper turns; pushing a plurality of magnetic conduction connectors 2 with windings 9 into the stator yoke part 1 for fixing, wherein the fixed slot wedges 7 of the magnetic conduction connectors 2 are matched with the slot holes 6 of the stator yoke part 1; then, pushing the magnetic slot wedge 5 into the slot wedge hole 8 of the adjacent magnetic conductive connector 2; the entire assembled stator core with windings 9 is annealed, vacuum painted, cured and potted to form an axial flux stator core using a composite material.

The invention fully utilizes the advantage of low iron loss of the amorphous material, reduces the manufacturing process flow of the amorphous alloy material, and does not need to use laser cutting, electric spark cutting or water jet cutting process, thereby reducing the performance loss from the amorphous strip to the amorphous iron core caused by the manufacturing process.
2. The magnetic conduction connector 2 has a complex structure, if the traditional silicon steel material is adopted for manufacturing, a large amount of silicon steel material is wasted, and under the condition of ensuring the same structural strength, the silicon steel material needs to occupy a larger space structure, so that the space of the magnetic conduction sandwich 3 is occupied, the occupation ratio of the amorphous alloy material is reduced, and the iron loss of the stator core is improved. The invention fully utilizes the high plasticity advantage of the soft magnetic material and increases the duty ratio of the amorphous alloy material as much as possible.
3. The invention fully utilizes the advantages of high saturation magnetic density and material stability of the silicon steel material, adopts the traditional silicon steel material for the stator yoke part 1, and enables the yoke part serving as a part of a magnetic circuit to pass through a stronger magnetic field, thereby reducing the thickness of the yoke part when the motor is designed, and further reducing the volume of the stator core.
4. The traditional winding method requires a great deal of manual participation, and is difficult to realize mechanization and automation. The invention carries out modularized design on the tooth part of the stator, and coils of the concentrated winding 9 can be wound on the magnetic conductive connector 2 in advance, thereby realizing automatic winding and improving labor production efficiency.
