Baking lacquer

Electric sheet baking lacquer for optimum motor performance

Backlack electrical steel: Innovative solution for powerful electric motors

The electrical steel baking varnish is a key technology in the production of modern electric motors, generators and transformers. This innovative coating improves the efficiency and durability of the components by ensuring a strong bond between the sheets while minimizing losses. HAILTEC offers high-precision, back-coated electrical sheets that are specially tailored to the requirements of your applications.

What is electric sheet baking lacquer?

The term Backlack refers to a special coating that is applied to the surface of electrical sheets. This coating is activated during the manufacturing process by heating, which causes the sheets to bond together. The baking varnish ensures that the laminations are firmly bonded without the need for additional welding or gluing techniques.

Advantages of electric sheet baking lacquer

The use of baked enameled electrical sheets has numerous advantages:

Minimization of eddy current losses: The baking varnish prevents electrical conductivity between the sheets and thus reduces energy losses.
High mechanical stability: The bonded metal sheets ensure a robust and vibration-resistant structure.
Noise reduction: Back-painted plates significantly reduce operating noise.
Simple processing: The baking varnish enables fast and efficient production.
Environmentally friendly: As no additional adhesives are required, this technology is particularly sustainable.

How does the baking lacquer process work?

The baking lacquer process involves several precise steps:

1. coating:

2. cutting to size:

3. stacking:

4. heating:

The electrical sheets are coated with a thin layer of baking varnish.

The sheets are cut to the desired shape, typically by laser fine cutting for smaller quantities

The coated trays are stacked in the correct order.

The baking varnish is activated by controlled heating and the trays bond to form a solid unit.

Materials for electric sheet baking lacquer

High-quality electrical steel sheets that are suitable for the baked enamel process are usually made of:

Silicon steel:
- Excellent magnetic properties
- Low losses due to eddy currents
High-performance alloys:
- For special applications such as in aviation or medical technology

The baked varnish layer is tailored to the specific requirements of the motor or generator in order to achieve optimum results.
