Successful development of a dual axial gap type high-speed induction motor!
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 an air-cooling system and a diameter of approximately 10 cm.
Introduction of the article published in the March 22nd edition of the Nikkan Kogyo Shimbun. The development is centered around Professor Masato Enokizono (Specially Appointed Professor at Nippon Bunri University, Emeritus Professor at Oita University, and Visiting Professor at RWTH Aachen University) who conceived 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 even small sizes can achieve high output through high-speed rotation, but heat generation in the iron core is a challenge. - Currently, electromagnetic steel sheets are about 300μm thick; reducing thickness helps suppress heat generation, and this time, a practical 80μm steel sheet has been invented. - Thin steel sheets are difficult to laminate, so they will be mass-produced using a wound lamination method. A dual-type rotor that sandwiches the rotor from both sides will further increase torque. - EV synchronous motors generate significant heat in the coils, and magnets are sensitive to heat, necessitating a water cooling system; 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 for high-speed operation include coil winding, processing of ultra-thin electromagnetic steel sheets, and low friction for the rotating shaft. We aim for practical application through joint research with specialized technology manufacturers.
