The design and custom processing of axial flux motor stator lamination stacks is a comprehensive engineering technology involving multiple fields such as material science, electromagnetics, mechanical engineering and precision manufacturing. Here is an overview of some key points of the process:
1. Design phase:
1.1 Magnetic circuit design
The characteristic of an axial flux motor is that its magnetic field is distributed along the axial direction. Therefore, when designing the stator laminations, it is necessary to accurately calculate the length of the magnetic circuit, the width of the air gap, and the shape and size of the laminations to optimize the motor's performance. Magnetic flux density and reluctance losses.
1.2 Lamination geometry
The laminations are usually made of silicon steel sheets. Their shape, thickness and lamination method (such as inclined groove, flat groove or mixed groove structure) will affect the performance and efficiency of the motor.
1.3 Insulation treatment
Insulation treatment is required between laminations to prevent short circuits. The selection and treatment of insulating materials are also an important part of the design.
2. Material selection:
2.1 Silicon steel sheet
Choose high-quality silicon steel sheet with high magnetic permeability and low loss characteristics to reduce iron loss during motor operation.
2.2 Insulation material
Choose insulating paint or film that is suitable for the operating temperature, has good mechanical properties and electrical insulation properties.
3. Lamination processing:
3.1 Stamping
Use precision molds to stamp silicon steel sheets to ensure the dimensional accuracy of the laminations and the consistency of the groove structure.
3.2 Lamination stacking
The stamped silicon steel sheets are stacked in an orderly manner according to the design requirements. The gaps between the laminations are properly controlled, which can not only ensure the smooth flow of magnetic flux but also limit the eddy current loss.
4. Custom processing:
4.1 Fixing process
The stack of laminates is fixed into one through welding, gluing or mechanical fastening to ensure the stability of the motor during operation.
4.2 Winding embedding
According to the motor design, the coil windings are accurately embedded into the lamination slots to form a complete electromagnetic circuit.
4.3 Quality inspection
Conduct comprehensive quality inspection on the custom-processed stator lamination stack, including but not limited to dimensional accuracy, surface quality, insulation performance and magnetic performance.
5. Optimization and simulation:
The motor design is optimized and simulated through finite element analysis (FEA) and other means to ensure that the final product meets the predetermined performance indicators.
In short, the design and custom processing of the axial flux motor stator lamination stack is a highly refined process that requires a combination of theoretical calculations, experimental verification, and advanced manufacturing technology to produce efficient, stable and specific applications. products in demand.
