FAQS

Stator and Rotor Lamination Bonding Manufacturer In China Impact On Motor Performance

Q: What is the difference between adhesive bonding technology and traditional riveting or welding?

Connection mechanism	Adhesive bonding forms chemical bonds through chemical reactions, while riveting and welding form connections through mechanical locking and melting of materials, respectively.
Heat effect	Adhesive bonding has no heat affected zone and does not affect material properties, while riveting and welding may cause material deformation or performance changes.
Precision and uniformity	Adhesive bonding provides higher precision and uniform stress distribution, while riveting and welding may cause stress concentration.
Flexibility	Adhesive bonding has a certain degree of flexibility, absorbing vibration and impact, while riveting and welding connections are usually more rigid.

Q: What is the manufacturing process for adhesive bonded laminated stack?

Prepare silicon steel sheet	Cut the silicon steel sheet to the appropriate size and shape according to the design requirements.
Surface treatment	Clean the surface of the silicon steel sheet, remove oil and impurities, and ensure good bonding effect.
Gluing	Apply specialized adhesive evenly on the surface of the silicon steel sheet.
Stacking	Stack the coated silicon steel sheets in order to ensure alignment and tight contact.
Pressure curing	Apply pressure to tightly bond the laminations and cure the adhesive under certain temperature and time conditions.
Post processing	Trim, inspect, and package the cured stack as needed.

Q: What are the special applications of adhesive bonding technology in new energy vehicle motors?

Increase power density	Through adhesive bonding, close contact between silicon steel sheets is achieved, increasing magnetic flux density and thus increasing the power output of the motor.
Enhanced heat dissipation performance	Adhesive bonding helps to form a continuous heat conduction path, improving the heat dissipation efficiency of the motor.
Weight reduction and compact design	Adhesive bonding allows for the use of thinner silicon steel sheets and more compact structural designs, helping to reduce motor weight and improve energy efficiency.

Q: Can the adhesive of the iron core withstand high temperatures?

The adhesive of the iron core can indeed withstand high temperatures. The type of adhesive selected is crucial in the design and manufacturing process. Usually, the adhesive used for bonding iron cores is high-temperature resistant adhesive, which can maintain stability in high-temperature environments without losing adhesion. These adhesives are specially formulated to ensure that the adhesive strength and structural integrity can still be maintained under normal operation of the motor and extreme conditions, such as high temperature operation.

Therefore, the use of high-temperature resistant adhesive for iron core bonding is reliable and can adapt to the working requirements of motors in high-temperature environments.
