Custom adhesive bonding motor stator and rotor iron core

Stator and Rotor bonding is also called bonded stator and rotor lamination technology. it uses high-temperature glue or epoxy achieve realize the lamination stacks magnet bonding process and ensure the stators and rotors do not need any interlock or welding to reach the lowest iron loss and get the highest motor efficiency.

Motorneo’s ability to provide custom glue bonding stator and rotor stacks to meet client-specific motor stacks shapes, patterns, and sizes. The bonded motor lamination is mainly made of progressive stamping, laser cutting, and EDM wire cutting.

Our custom glue bonding electrical steel lamination services cater to a diverse range of industries. Such as pump motors, aerospace drone motors, rail transportation linear motors, permanent magnet synchronous elevator motors, fans motors, robotic motors, and new energy vehicle motors, including those wheel motors.

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.

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.
