Technology

Anticipating the trends of these times when society is rapidly changing, we take action across our organization to accelerate our technology development initiatives to match the demands of our diverse customers for each individual project based on our unique technical foundation and matrix organizing customer needs that have been accumulated over many years of experience. Our goal is motor technology development that puts the customer first, that contributes to our customers’ profitability, that is friendly to the environment, that is highly reliable and that can be supplied in a stable fashion.
In addition, we do not rely strictly on in-house research and development but actively cooperate in connection with domestic and international enterprise, academic and research institutes to promote breakthrough for the new, next generation of motor technology.
