General FAQs
uick answers to questions you may have. Can’t find what you’re looking for? Get in touch with us and we’ll provide you with more information.
How do the thickness and material properties of stator core laminations affect performance?
The motor’s overall performance and efficiency are impacted by the lamination thickness. Thinner laminations reduce eddy current losses, while the material properties, such as silicon content, affect magnetic permeability and conductivity, influencing the motor’s overall efficiency.
Can stator and rotor laminations be purchased separately?
Yes, stator and rotor laminations can be purchased separately. You can order each component according to your motor requirements, ensuring compatibility with the rest of the motor assembly.
How are stator and rotor laminations tested for quality?
Quality testing for stator and rotor laminations includes dimensional checks, magnetic testing, surface inspections for defects, and electrical conductivity tests to ensure the laminations meet strict performance and reliability standards.
