Computer Networking

Computer networking is a way of connecting several computers. It allows several computers to communicate with each other. There are two different ways in which this can happen. It can be set up to be a permanent arrangement that is fixed with cables or it can be done through a temporary situation such as that of modems.

Get Connected To Wi-Fi  

Wi-Fi, short for wireless fidelity refers to a set of wireless networking technologies more specifically referred to as any type of 802.11 network, 802.11b and 802.11a, dual band. The word Wi-Fi was built by an organization called the Wi-Fi Alliance. They overlook tests that confirm the production.

Linear Stepper Motors Technology

A linear induction motor is made up of an inductor which is made of individual cores with a concentrated polyphase. Linear motors can be directly substituted for ball screw drives, hydraulic drives, pneumatic drives, or cam drives. A linear induction motor is basically what is referred to by experts as a "rotating squirrel cage" induction motor. The difference is that the motor is opened out flat. Instead of producing rotary torque from a cylindrical machine it produces linear force from a flat machine. The shape and the way it produces motion is changed, however it is still the same as its cylindrical counterpart.

There are no moving parts, however and most experts don't like that. It does have a silent operation and reduced maintenance as well as a compact size, which appeals many engineers. There is also a universal agreement that it has an ease of control and installation.

These are all important considerations when thinking about what type of device you want to create. The linear induction motor thrusts ratio varies depending mainly on the size and rating. Speeds of the linear induction motor vary from zero to many meters per second. Speed can be controlled. Stopping, starting and reversing are all easy. Linear induction motors are improving constantly and with improved control, lower life cycle cost, reduced maintenance and higher performance they are becoming the choice of the experts.

Linear motors are simple to control and easy to use. They have a fast response and high acceleration. Their speed is not dependant on contact friction so it is easier to pick up speed quickly. Stepper motors are a special kind of motor that moves in discrete steps. When one set of windings is energized the motor moves a step in one direction and when another set of windings is energized the motor moves a step in the other direction.

The advantage of stepper motors that the position of the motor is "known". Zero position can be determined, if the original position is known. Stepping motors come in a wide range of angular resolution and the coarsest motors typically turn 90 degrees per step. High resolution permanent magnet motors are only able to handle about 18 degrees less than that. With the right controller stepper motors can be run in half-steps, which is amazing. The main complaint about the stepper motor is that it usually draws more power than a standard DC motor and maneuvering is also difficult.
