Machine An electrical machine is the generic name for a device that converts mechanical energy to electrical energy, converts electrical energy to mechanical energy, or changes alternating current from one voltage level to a different voltage level.he word machine derives from the Latin word machina, which in turn derives from the Greek (Doric μαχανά makhana, Ionic μηχανή mekhane contrivance, machine, engine, a derivation from μῆχος mekhos means, expedient, remedy). A wider meaning of fabric, structure is found in classical Latin, but not in Greek usage.

Fan (machine) A household electric floor fan. A fan is a machine used to create flow within a fluid, typically a gas such as air. The fan consists of a rotating arrangement of vanes or blades which act on the fluid. The rotating assembly of blades and hub is known as an impeller, a rotor, or a runner. Usually, it is contained within some form of housing or case.

Bending machine (manufacturing) A bending machine is a forming machine tool (DIN 8586). Its purpose is to assemble a bend on a workpiece. A bends is manufactured by using a bending tool during a linear or rotating move. The detailed classification can be done with the help of the kinematics. (M.or producing single pieces as well as small batches with the same precision and efficiency as series-produced parts, a spring back compensation is helpful. A bending accuracy of +/- 0.2° starting from the first work piece is achieved due to calculated spring back compensation and the use of electronic tools.

- S imple machines help us make better use of our muscle power to do work. A simple machine produces force and controls the direction of a force. Simple machines help us lift, pull or raise items, change the direction of the force, increase the force, split things, fasten things, and cut things. We all use simple machine s every day, opening a door, turning on the water faucet, going up stairs, or opening a can of paint. Simple machines make work easier.

Hydraulic machinery Hydraulic machines are machinery and tools that use liquid fluid power to do simple work. Heavy equipment is a common example. In this type of machine, hydraulic fluid is transmitted throughout the machine to various hydraulic motors and hydraulic cylinders and becomes pressurised according to the resistance present.

Engine An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines burn a fuel to create heat which is then used to do work. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air; and clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion.

Simple machine Usually the term refers to the six classical simple machines which were defined by Renaissance scientists: Lever Wheel and axle Pulley Inclined plane Wedge Screw A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the load.

Simple Machines There are six types of simple machines: lever, pulley, inclined plane, wedge, screw, and wheel and axle. Each machine affects the direction or the amount of effort needed to do work. Most mechanical machines, such as automobiles or power tools, are made up of hundreds of parts. However, no matter how complex a machine is, it is composed of some combination of these six simple machines.
