Make Less-vibrating Products

Vibration occurs as a motor rotates, and becomes larger as the motor’s rotational frequency increases. Until recently, 5,000 revolutions/min. were considered sufficient for server fans; now, however, as more heat is generated after servers’ processing capacity improves, those fans are required to rotate 20,000 times per minute. At Nidec, we must accommodate the needs for faster processing and communications with larger volumes of data. To the voices for an advanced IT society, Nidec gives answers based on its persistence to accuracy that does not allow even a slight vibration or loosening, and on its revolutionary technologies that eliminate vibration.

Nidec’s Solutions with Low-vibration Products

Automated Transportation Robot Drive Module

Generate synergies within the Nidec Group to develop a high-efficiency drive module.

Helium-Filled Hard Disk Drives

HDDs filled with helium have improved read/write precision and lower power-consumption due to minimized disk vibration caused by drag.

Power Steering Motors (1st – 3rd Generations)

Nidec is developing and producing high-performance EPS motors by utilizing our motor design, control and mass production technologies that we have cultivated over the years. This is our development story of the first to third generations of power steering motors.
