Learn what a contactor is, how it works, how to wire a contactor, and the difference between a contactor and a relay. Listen to this article In this article, we will be talking about contactors. We will explain what a contactor is and how they work. We will also explain how to wire...
Ahard diskis a circular platter coated with a thin layer of magnetic material. The disk is inserted on a spindle and spins at speeds of up to 15,000 revolutions per minute (rpm). As it rotates, data is written on the disk surface using magnetic recording heads. A high-speedactuatorarm ...
How Solid-state Drives Save and Access Data In this picture, it's easy to see this hard drive's platters, which look a bit like CDs stacked one on top of another, and an actuator arm. ©iStockphoto.com/jpa1999 On the outside, solid-state drives look just like HDDs. They're...
The rotor speed of the servo motor is controlled by the input signal. In the automatic control system, it is used as an actuator and has the characteristics of a small electromechanical time constant and high linearity. It can convert the received electrical signal into the angular displacement ...
This type of system is useful for controlling systems with many variables and ensuring accurate and consistent performance. The basics of a closed loop system involve a sensor to measure the output, a control unit to compare the output to the desired output, and an actuator to modify the syste...
Dozens of types and sizes of keylock switches are available. You can have anywhere from one to 5,000 key codes (the uniqueness of the key) dependent on the series.The PVK4 Series is rated IP65 for dust and moisture protection with a keylock actuator option rated IP40. The switch features...
Note that the actuator arm is what positions the read-write head in the desired location on the platters. Overall, the precise mechanics of a hard drive allow for efficient data storage. Components of a hard disk drive At the heart of every hard drive is a set of essential parts that are...
How It Works Steam HammerWhat is Steam Hammer & How to Eliminate Steam Hammer Steam Hammer/Cavitation/Vibration If your heating equipment is violently shaking, then it is a concern that needs to be addressed. It is not only dangerous, but it also can be an expensive maintenance problem. Exte...
A lightweight and energy-efficient architecture for wireless sensor networks It is suitable for sensor-actuator systems, is based on IEEE 802.15.4 and constitutes a more lightweight alternative than Zigbee. We provide a vision ... MA Lopez-Gomez,JC Tejero-Calado - 《IEEE Transactions on Consumer...
