Capability for stamping stator and rotor
The Motorneo stator rotor lamination pack manufacturing process centers around the use of high-speed progressive die stamping, compound stamping, and single-slot notching.
Progressive die stamping is suitable for small laminations and segmented stator laminations. Compound stamping is cost-effective for medium and large electric motor laminations. Rotary notching is suitable for large laminations and prototypes.
While many companies utilize 0.35mm and 0.5mm silicon steel sheet designs for adhesive motor lamination, we have taken innovation a step further. Our team has successfully designed and manufactured tungsten steel progressive molds that accommodate the use of ultra-thin 0.2mm silicon steel sheets.
Insulation coating technology for motor stator
Motorneo has multiple automatic electrostatic epoxy insulation coating lines to coat stator rotors. Our process adheres to the H Class standard.
This epoxy power process involves applying a 3M epoxy resin coating, fortified with high-quality insulation powder. This not only provides a robust protection layer to shield against environmental factors and wear but also ensures electrical insulation.
Surpassing traditional insulation methods like paper and plastic over molds in both performance and cost-efficiency, our epoxy coating streamlines the winding process, facilitating smoother motor assembly automation.
Stator winding process
We also offer stator winding services, employing copper wire coil winding as a staple of our production.
Copper, renowned for its exceptional electrical conductivity and heat resistance, ensures the reliability and efficiency of our stator windings.
Motorneo offers automatic and manual winding technologies to the exact specifications required for your specific motor applications. Our stator winding services cater to various industries, including automotive, power tools, household appliances, industrial robotics, drones, wind turbines, and beyond.

Glue bonding Motor Core FAQs
Glue bonding enhances motor stability and reliability, lowers lamination separation risk, and results in quieter, more energy-efficient operation.
The stator and rotor use 0.1mm-1mm thickness electrical steel (silicon steel) materials to provide the required magnetic properties. The electrical steel is usually coated with an insulating layer to prevent electrical eddy currents.
The adhesive materials use epoxy resins due to their excellent adhesive properties, electrical insulation, and resistance to temperature and environmental factors.
Glue bonding is commonly used in a wide range of motor types. Including those used in industrial motors, electric vehicle motors, generators, servo motors, RC car motors, and Drones motors.
Dot glue bonding involves applying adhesive in a dot-like pattern, while Full surface bonding covers the complete surface of the laminations to improve rigidity and optimized alignment, perpendicularity, and parallelism. The choice between the two depends on the specific motor design and requirements.
