• Did you know2024

  Nidec built an empire on a motor most people have literally never seen: the tiny precision spindle motor that spins the platters inside a hard disk drive, where it holds a commanding global share. From that minuscule base it leveraged one core competency — brushless motor design — across an astonishing range of sizes and uses: the cooling fans in laptops and data centers, the motors in printers, the BLDC motors in washing machines and air conditioners, robots and machine tools. And it is now betting its future on the opposite extreme of scale: EV traction motors, the e-axle "drive units" that propel electric cars. So a single company's motors span roughly six orders of magnitude in size, from a gram-scale HDD spindle to the heart of an EV powertrain — a breadth of "everything that spins" that makes Nidec one of the most pervasive and least visible suppliers in modern hardware.

• Chokepoint2024

  The world's "cold" data — the vast archives still stored on spinning hard disks in data centers — depends on motors from a tiny group of companies, with Nidec dominating the HDD spindle-motor market. Pair that with TDK's near-monopoly on the read/write heads, and the hard-disk drive (still the cheapest way to store bulk data at scale) rests on a handful of Japanese component makers. More broadly, the global market for small precision motors is itself concentrated: Nidec, Johnson Electric and MinebeaMitsumi together control a majority of micromotor supply. Because these motors are embedded invisibly in everything from cars to appliances to disk drives, that concentration is a quiet, system-wide chokepoint — a disruption among a few motor makers would ripple across data storage, automotive and consumer hardware simultaneously, in products that never advertise whose motor is inside.

• Origin2023

  Nidec Corporation was founded in 1973 in Kyoto by Shigenobu Nagamori with 23,000 yen of capital -- approximately $75 at the time -- and three part-time employees working from a 165 m2 factory. Nagamori had been fired from his previous employer and started Nidec specifically to make precision small motors. The HDD spindle motor was Nidec's breakthrough product: in 1979, Nidec developed the world's first brushless DC spindle motor for Winchester hard disk drives, which IBM was introducing at the time. By 1990, Nidec had captured the dominant global market share in HDD spindle motors -- a position it has maintained for 35 years at near-100% share. From 1973 to 2024, Nagamori's acquisition-driven growth strategy (over 70 company acquisitions) built Nidec into a 1-billion-unit-per-year motor company with operations across HDD, appliances, industrial automation, and increasingly EV traction -- all from a Kyoto starting point of 3 part-time workers in a 165 m2 shed.
