I am working on an electrical engineering project. However, I have come across a specific mechanical engineering problem. I have attached an image to describe what I want to do. I have primarily a stator core (made out of electrical steel laminated sheets) named part number "1". I have a double-sided adhesive insulation tape named part number "2". Lastly, I have a sheet of electrical steel, which I call a plate, named part number "3". The part number 2 will be put on the inner diameter of part number 1. After that, part number 3 will be put on the inner diameter of part number 1, which already has the part number 2. The part number 3 is made up of multiple strips (as you can see in the figure). Can you guys tell me the most efficient and precise way of putting these parts together, like I described above? You are welcome to give the suggestions regarding techniques or the tools. You are welcome to ask any follow-up questions.

I expect it will take more than double-sided tape2 to stop plate3 moving on core1. Plate3 will get hot due to eddy currents. That makes organic adhesives questionable. Maybe you will need a mineral cement and some form of mechanical lock.

There would need to be some way to align the poles of core1 with the fingers of plate3. I assume the poles are equal in number. Plate3 would need to be made to collapse, then expand in diameter, so it could be inserted, then unrolled or expanded onto the inside of core1. That would require one cut, or a 'z' bend in each joiner between the sub-plates of plate3.
 

FAQ: Attach plates (my design) to the stator core of the machine

What materials are best suited for attaching plates to the stator core?

The best materials for attaching plates to the stator core depend on the specific requirements of the machine, such as thermal conductivity, mechanical strength, and electrical insulation. Common materials include high-strength adhesives, epoxy resins, and mechanical fasteners like bolts or screws. The choice of material should ensure a secure attachment while maintaining the integrity and performance of the stator core.

How do I ensure proper alignment of the plates on the stator core?

Proper alignment can be ensured by using alignment tools or jigs specifically designed for your stator core and plate dimensions. Precision measurement tools such as calipers and micrometers can also help in maintaining accurate alignment. It's crucial to follow the design specifications and guidelines provided to avoid misalignment, which can affect the machine's performance.

What are the common challenges faced during the attachment process?

Common challenges include maintaining precise alignment, ensuring strong and durable bonds, dealing with thermal expansion and contraction, and avoiding any potential damage to the stator core or plates. Additionally, ensuring that the attachment process does not introduce any electrical interference or compromise the magnetic properties of the stator core is crucial.

How can I test the strength and durability of the attachment?

Testing the strength and durability of the attachment can be done through various methods such as tensile tests, shear tests, and thermal cycling tests. Non-destructive testing methods like ultrasonic testing or X-ray imaging can also be used to inspect the integrity of the attachment without damaging the components. Regular inspection and maintenance schedules should be implemented to monitor the attachment over time.

What safety precautions should be taken during the attachment process?

Safety precautions include wearing appropriate personal protective equipment (PPE) such as gloves, safety glasses, and protective clothing. Ensure that the work area is well-ventilated, especially if using adhesives or chemicals. Follow all safety guidelines and protocols for handling tools and materials. Additionally, ensure that the machine is powered off and properly grounded to prevent electrical hazards during the attachment process.
