METHOD FOR MANUFACTURING STATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18030793 titled 'METHOD FOR MANUFACTURING STATOR
Simplified Explanation
This patent application describes a method for manufacturing a stator, which is a component used in electric motors.
- The method involves two main steps: cross section forming and coating.
- In the cross section forming step, the coil portion of the stator is compressed to achieve a desired sectional shape.
- In the coating step, an insulation coating is applied to the coil portion to provide electrical insulation.
- After these steps, a common heat treatment is performed.
- The heat treatment involves annealing the coil portion to improve its mechanical properties.
- The heat treatment also involves baking the insulation coating to enhance its durability.
- The key innovation is performing both the annealing and baking in a single heat treatment process.
- This simplifies the manufacturing process and reduces production time and costs.
Original Abstract Submitted
This method for manufacturing a stator includes, after a cross section forming step for forming a sectional shape of a coil portion by compressing the coil portion and a coating step for applying an insulation coating to the coil portion, a common heat treatment step for performing, by the same heat treatment, annealing of the coil portion whose sectional shape has been formed in the cross section forming step and baking of the insulation coating applied to the coil portion in the coating step.
