Electromagnetic Field Analysis Software 【μ-E&S Vector Magnetic Characteristic Analysis / Development Case】

A small high-power motor developed by Professor Masato Enokizono of the Vector Magnetic Characteristics Research Institute, capable of continuous operation at 10,000 RPM with a diameter of approximately 10 cm and air cooling.

Introduction of the article published in the March 22nd Nikkan Kogyo Shimbun. Development centered around Professor Masato Enokizono (Specially Appointed Professor at Nippon Bunri University, Emeritus Professor at Oita University, Visiting Professor at RWTH Aachen University) who devised the "Vector Magnetic Property Analysis" technology. *The article can be found at the following links: 1) Vector Magnetic Property Technology Research Institute http://www.vector-magtec.jp/index.html 2) Mutec HP news https://www.mutec.org/ - Induction motors are used in various industries; they are simple, robust, resistant to harsh environments, low-cost, and maintenance-free. - For high output, larger sizes are needed, and high-speed rotation in smaller sizes can achieve high output, but heating of the iron core is an issue. - The current electromagnetic steel sheets are about 300μm thick; thinning them can suppress heating, and this time we have invented practical 80μm steel sheets. - Thin steel sheets are difficult to laminate, so we will mass-produce them using a winding lamination method. A dual-type rotor that sandwiches the rotor from both sides will further increase torque. - EV synchronous motors generate a lot of heat in the coils, and magnets are sensitive to heat, requiring water cooling systems; the developed induction motor uses air cooling, and low output can be integrated into four wheels. - A new choice that overturns the common belief that "induction motors are impossible!" The challenges of increasing speed involve coil winding, processing ultra-thin electromagnetic steel sheets, and low friction for the rotating shaft. We aim for practical application through joint research with specialized technology manufacturers.
