Ultra-thin non-directional electrical steel strip STseries

Ideal for high-efficiency motors with both low loss and miniaturization

It is an ideal material for motor cores, etc., because its magnetic properties are isotropic. The thinness allows extremely low iron loss in the high rotation range, and by having a higher magnetic flux density than other materials, it is possible to achieve both high efficiency and miniaturization.

Low Loss	By reducing the plate thickness, eddy currents can be suppressed and loss can be reduced.
Miniaturization	It has a high magnetic flux density and contributes to the miniaturization of motors, etc.
Optimal Range of Use	It has a higher magnetic flux density than other materials at a working frequency of 400Hz to 40kHz, making it possible to reduce the size of motors, etc.
Insulating Coating	A superior insulating coating maximizes material properties. The coating has a high heat resistance temperature and can maintain a stable coating even at high temperatures (up to 850°C).
Raw Material	Fe (0.003)Si steel (raw material of Nippon Steel Corporation) is used for ultra-thin electrical steel strips. A highly reliable electromagnetic steel strips material with a track record of over 50 years of use.

Stator glue bonding + wire cutting method. Fast proofing, testing motor core performance superiority.

Bonding process, superior performance, smaller size.

Glued motor core, more compact assembly, improve the efficiency and performance of the motor, while also reducing noise and vibration.
