Silicon Steel Coil in Various Applications
The silicon steel coil for electric motor provides good magnetoelectric properties. They are available in many surface treatments such as semi-organic coating, painting, PE coating, and many more.
Longbank silicon steel coil for the generator is manufactured by a cold-rolled process. It can be coated rolled, mirror surface, or as requested.
The silicon steel coils for appliances provide accurate thickness, beautiful, and smooth surface. Aside from that, it also provides excellent mechanical properties in terms of machining performance.
The silicon steel coils for transformer are known for the following benefits: less coating weight, good corrosion resistance, high-temperature resistance, good weldability, excellent coating, and high dimensional accuracy.
The silicon steel coil is widely utilized in most power electronic industries. Mainly are current transformers, distribution transformers, power transformers, and different iron cores.
In addition, the silicon steel coils are suitable for various electronic systems, inductor cores, household appliances, low-frequency chokes and transformers, reactors, relays, and many more.
The silicon steel coils are the ferritic alloys of silicon and iron. The silicon content increases electrical resistivity and enhance magnetic softness. The silicon steel coils have excellent magnetic properties that makes them ideal in transformers and motors.
The silicon content is about 2 wt.% which can reduce saturation magnetization and decreases Curie temperature. There are two forms in producing silicon steel coil: Non-oriented (NO) and grain-oriented (GO).
A silicon steel coil is compost of 97% pure iron. It provides corrosion resistance when there is a thin coating being applied. Without coating, the silicon steel coils will rust in humid or wet environments.
The silicon steel coil is popular for the following characteristics:
- Low iron damage
- Smooth surface
- Excellent magnetoelectric properties
- High magnetic sensitivity
- Uniform thickness
