Capabilities For Electrostatic Epoxy Coating Insulation Process

The Electrostatic Epoxy Coating Process is a critical step in enhancing the insulation and protection of motor cores, such as stator and rotor components. Our automatic electrostatic epoxy coating lines allow insulation of the iron laminated core.

The process begins with the thorough cleaning and preparation of the motor stator and rotor lamination stacks, ensuring it is free from contaminants and defects.

Once the iron laminated core is prepared, we use the specialized electrostatic electrical insulation coating machine to apply the epoxy coating. The electrostatic charge ensures that the epoxy particles are uniformly attracted to the core’s surface, creating a consistent and even layer of insulation.

Our capabilities to C-5 and C-6 electrical steel coatings for armature laminations stack up to 350mm outside diameter, with or without shafts.

Advantages of Electric Motor Lamination Stacks Epoxy Power Coating Insulation

Enhanced Insulation

Epoxy powder coating insulation offers a superior level of electric motor insulation. It creates a protective barrier that reduces the risk of short circuits and enhances the overall reliability of your electric motor.

Thermal Efficiency

Efficient heat dissipation is a key factor in prolonging the lifespan of electric motors. It not only provides a durable and uniform protective layer but also improves heat dissipation. This ensures that your motor operates within optimal temperature ranges.

Corrosion Resistance

Electrostatic epoxy powder coating provides a continuous dielectric insulating layer with strong chemical and heat resistance to protect motor Coil windings. This resistance to corrosion is essential for outdoor, marine, or industrial environmental motors.


We specialize in designing and fabricating stator and rotor cores that match your voltage requirements. Our expertise allows us to choose the right materials and apply the coating with the utmost precision.
