< CEO's Profile >

CEO of DMT Co., Ltd
After graduating from a local industrial high school, he became a technical advisor for Samsung, via working for the Shinano Tokki. In 1990, he established DMT company and became the company's president. He also works for patent firms in Tokyo as an advisor, business consultant, and lecturer. His hobbies are music and fishing.
"Since we have just one life, I always go all-out to create what I envision. I established my own company to spread this philosophy. So, I'm trying my best every day," said Mr.---, the CEO of DMT Co., Ltd
In his high school days, when he was 16 years old, he had a traffic accident on his motor bike. He was caught under a large track and received 125 stitches for his wounds. But he miraculously survived. This was the crossroad in his life.
After graduating from high school, he got a job as a motor maker. But when he was 24 years old, he left the company and started his own business to pursue his enthusiasm for creative andevours. In October 1990, he established the DMT company.
Taking advantage of the technology which he learned as a motor maker, he has been trying to design and manufacture measurement devices and magnetizing technology, which contributes to the improvement of the motor characteristics, from the user point of view.
"Since I used to design motors, I have been pursuing products and magnetizing yoke technology, which fulfills the customers' needs with regards to motor characteristics," said Mr.---.
He was born and grew up by Lake Suwa in Nagano. His company is also located in the same area, where many electronic, electronic parts, and precision instrument enterprises are located. The company has developed as a leader in its field while the technology race has intensified.
Magnetizing means to give magnetism to motors, which requires high accuracy, until they become saturated and create a magnetic field in the coils in/out of the motor and the magnets. Since highly accurate rotations are made available by the tips of the magnetic pole shape, cogging torque and noise will be decreased.
Magnetizing coils can be magnetized on the N pole and the S pole. On the other hand, magnetizing yokes can produce various magnetizing patterns by creating a magnetic circuit with coils and a special material which has high magnetic permeability and a saturated magnetic-flux density. Also, the the magnetizing ripple analysis system, which analyzes the magnetic-flux ripple, amount of magnetic-flux on each pole, magnetizing angles, and the magnetizing area by measuring the magnetic-flux distribution automatically, occupies a top-class level in the industry.
We also contribute to society through professional magnetizing technology engineering. We have participated in ODA (Official Development Assistance) and research and development of superconducting bearings technology for flywheels with a project by NEDO (New Energy and Industrial Technology Development Organization).
"Since we started only with technology at our disposal, we would like to present our own unique products to the world," said Mr.---. As a professional technology engineering firm, they will continue to play their part in the Japanese manufacturing industry.

Equipment in the Analysis Room

Equipment in the Analysis RoomWe set up the Analysis Room to improve the motor characteristics with magnetizing technology. We can conduct the analysis of noise by a noise level meter, a sound proof box, and a spectrum analyzer (FFT). Analysis of cogging Torque and Torque ripple will be done by a Torque Gauge and a Back EMF measuring instrument. Also, the magnet analyzer can analyze the surface magnetic-flux ripple simultaneously with the magnetizing experiments. After a continually consultation with a customer, we can begin an analysis immediately. It is our goal to improve the motor characteristics.
