NMB Technologies Corporation is a MinebeaMitsumi Group company; the world’s largest manufacturer of NMB miniature ball bearings and a volume leader in the design and manufacturing of precision electro-mechanical components such as small motors, backlight and LED lighting products, and sensors. NMB provide advanced technology solutions for automotive, medical, consumer, industrial and smart cities markets.

The main purpose of bearings is to prevent direct metal to metal contact between two elements that are in relative motion. This prevents friction, heat generation and ultimately, the wear and tear of parts. It also reduces energy consumption as sliding motion is replaced with low friction rolling

A brush or carbon brush is an electrical contact, often made from specially prepared carbon, which conducts current between stationary and rotating parts of an electrical machine. Typical applications include electric motors, alternators and electric generators.&nbsp;

A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.

In engineering practice, the distinction between electrical engineering and electronics is usually based on the comparative strength of the <a href="https://www.britannica.com/science/electric-current" target="_self">electric currents</a> used. In this sense, electrical engineering is the branch dealing with “heavy current”—that is, electric light and <a href="https://www.britannica.com/technology/electric-power" target="_self">power</a> systems and apparatuses—whereas electronics engineering deals with such “light current” applications as <a href="https://www.britannica.com/technology/telephone" target="_self">telephone</a> and <a href="https://www.britannica.com/technology/radio-technology" target="_self">radio</a> communication, <a href="https://www.britannica.com/technology/computer" target="_self">computers</a>, <a href="https://www.britannica.com/technology/radar" target="_self">radar</a>, and automatic <a href="https://www.britannica.com/technology/control-system" target="_self">control</a> systems. 
电子电器，全部或主要部分由电子器件和电子线路构成的电器元件或装置的总称。如接近开关、晶体管温度继电器、同步接触器等。在信号检测、故障监视与保护等环节上优先实现电子化,而通断强电的操作则较多由有触点电器完成,由于自关断器的发展,很多已由诸如晶闸管、<a href="https://baike.baidu.com/item/%E7%BB%9D%E7%BC%98%E6%A0%85%E5%8F%8C%E6%9E%81%E5%9E%8B%E6%99%B6%E4%BD%93%E7%AE%A1/12731336" target="_blank">绝缘栅双极型晶体管</a>来完成。

The word "Hydraulics" originates from the Greek word ὑδραυλικός (hydraulikos) which in turn originates from ὕδωρ (hydor, Greek for <a href="https://en.wikipedia.org/wiki/Water" target="_self">water</a>) and αὐλός (aulos, meaning <a href="https://en.wikipedia.org/wiki/Plumbing" target="_self">pipe</a>). 
Lubricating oils are commonly used to reduce friction and wear and optimize the life of PT components such as bearings and gears. … In such applications, oil lubrication can wash the contaminants away from the bearings. Lubricating oils also serve as heat transfer fluids.
