Point of the Proposed Technology
Development of the magnetic material-added CFRP with magnetic substance added inside it
Using the magnetic material-added CFRP, a motor core is formed. Compared to the conventional motor core of silicon steel plate, more weight is reduced.
Using the magnetic material-added CFRP, a motor core is formed. Compared to the conventional motor core of silicon steel plate, more weight is reduced.
Effect(s)
The uniform addition of magnetic material in CFRP achieves ferromagnetism and reduced weight, resulting in reduction of load.
Conventional Technology
Through the manufacturing of thermosetting CFRP parts by CFRP cutting technology (Photo 1) and the manufacturing and selling of the carbon shoehorn which was made by the simplified press molding of a soft CFRP material before heat curing which is a thin-plate form material of SMC (Sheet Molding Compound) (Photo 2), we have cultivated the know-how about CFRP.
New Technology
Using the know-how, we successfully developed, in the joint research with Nagoya Institute of Technology, the "magnetic material-added CFRP" with magnetic material added to CFRP itself to impart ferromagnetism. The motor core formed using the magnetic material-added CFRP (Photo 3, left: conventional silicone steel plate, middle: manganese ferrite added, right: pure iron added) is lightweight compared to the conventional motor core of silicon steel plate, allowing reduction of rotation load due to weight, reduction of motor responsiveness and energy loss. The motor core formed using the magnetic material-added CFRP was developed for the first time in the world, and it is the latest technology that will be widely applied in various fields in the future.
