Nidec was established by Shigenobu Nagamori and three fellow engineers in 1973. From the outset, the company focused on small precision motors—the subject of Nagamori's research during his time as a student. In 1979, Nidec became the first company in the world to successfully commercialize a direct drive spindle motor for HDDs based on a brushless DC motor. Since then, the company has grown into the world's number-one comprehensive motor manufacturer by expanding its lineup to include a wide variety of products ranging from small precision to ultra-large motors and peripheral equipment through actively engaging in mergers and acquisitions of companies with advanced technology.
