Ultra-thin non-grain oriented electrical steel strip: STseries
Suitable for high efficiency motors due to both low core losses and downsizing
Due to its isotropic magnetic properties, it is mainly used as a lamination core in motors. The thin thickness enables extremely low iron loss in the high rotation range and a high magnetic flux density compared to other materials making it possible to achieve both high efficiency and downsizing.
Application example
-
Fan motor
-
Medical equipment
-
Consumer electronics
-
Tool
-
Medical equipment (Dental Drill)
Features
- Low core loss
- The eddy current can be suppressed by thinning thickness, and the iron loss can be reduced.
- Downsizing
- Contributes to downsizing of motors, etc. due to its high magnetic flux density.
- Optimal usage range
- Higher magnetic flux density than other materials at operating frequencies of 400 Hz to 40 kHz, enables downsizing of motors, etc.
- Insulation coating
- The excellent insulation resistance enables to take full advantage of the material properties. Furthermore, the high heat resistance temperature allows a stable film to be maintained even at high temperatures (up to 850°C).
- Raw material
- The ultra-thin electrical steel strip is made from Fe-3% Si steel (raw material from NIPPON STEEL) and is a highly reliable electrical steel strip has been used for over 50 years.
