WHAT IS ELECTRIC MOTORS?
How Does It Work? Electric motors, electrical energy is converted into mechanical energy to electrical machinery. Electric motors are most of the rotary mechanism. So many of these I should return mechanism. So they are similar, such as generator, separated by a core range of a fixed (stator) other moving (rotor) cylinder, two-axis co ferromanyetic armütür occurs. The electric motor is a devi |
rapid process that is used for electric motors, the conventional windings (coils), rather than rare, such as samarium-cobalt magnets, made from earth metal is benefiting from the hard magnets. Lack of engine vibrations to electricity, especially in these devices for monitoring precision orbit and is preferred for applications such as laser marking is made. Today, electric motors are often equipped with micro-processor and thus can be adjusted according to the needs of the user's work situation has been brought. Electric motors of direct current motors or engines, alternative space, such as synchronous motor or asynchronous motor is separated çeşirlere. Each of these has its own application area.

A weapon system is too big optronik engaged to a sensitivity at the target, the system is connected to DC motors, the rotor to measure the precise position is set with a sensor.

WHAT IS CENTRIFUGAL PUMP
A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping. Centrifugal pumps are used for large discharge through smaller heads. How it works Like most pumps, a centrifugal pump converts mechanical energy from a motor to energy of a moving fluid; some of the energy goes into kinetic energy of fluid motion, and some into potential energy, represented by a fluid pressure or by lifting the fluid against gravity to a higher level. The transfer of energy from the mechanical rotation of the impeller to the motion and pressure of the fluid is usually described in terms of centrifugal force, especially in older sources written before the modern concept of centrifugal force as a fictitious force in a rotating reference frame was well articulated.
The concept of centrifugal force is not actually required to describe the action of the centrifugal pump. In the modern centrifugal pump, most of the energy conversion is due to the outward force that curved impeller blades impart on the fluid. Invariably, some of the energy also pushes the fluid into a circular motion, and this circular motion can also convey some energy and increase the pressure at the outlet. The relationship between these mechanisms was described, with the typical mixed conception of centrifugal force as known as that time, in an 1859 article on centrifugal pumps, thus:[2] The statement "the mass of water ... must necessarily exert a centrifugal force" is interpretable in terms of the reactive centrifugal force—the force is not an outward force on the water, but rather an outward force exerting by the water, on the pump housing (the volute) and on the water in the outlet pipe. The outlet pressure is a reflection of the pressure that applies the centripetal force that curves the path of the water to move circularly inside the pump (in the space just outside the impeller, the exterior whirlpool as this author calls it). On the other hand, the statement that the "outward force generated within the wheel is to be understood as being produced entirely by the medium of centrifugal force" is best understood in terms of centrifugal force as a fictional force in the frame of reference of the rotating impeller; the actual forces on the water are inward, or centripetal, since that's the direction of force need to make the water move in circles. This force is supplied by a pressure gradient that is set up by the rotation, where the pressure at the outside, at the wall of the volute, can be taken as a reactive centrifugal force. This is typical of 19th and early 20th century writing, to mix these conceptions of centrifugal force in informal descriptions of effects such as that in the centrifugal pump. Differing conceptions and explanations of how a centrifugal pump works have long engendered controversy and animadversion.
For example, the American Expert Commission sent to the Vienna Exposition in 1873 issued a report that included observations that "they are misnamed centrifugal, because they do not operate by centrifugal force at all; they operate by pressure the same as a turbine water wheel; when people understand their method of operating we may expect much improvement." John Richards, editor of the San Francisco-based journal Industry, in his in-depth essay on centrifugal pumps, which also downplayed the signficance of centrifugal force in the working of the pump, remarked Modern sources say things like that the fluid "flows radially under centrifugal force",[4] or "centrifugal force flings the liquid outward".[5] Others counter that "there is no force at all, and a great deal of confused thinking."[4] Some are more careful, attributing the outward force to the impeller, not to centrifugal force: "the impellers throw the water to the outside of the impeller case. This centrifugal action is what creates the pressure..."[6] Even serious texts that explain the working of the pump without mention of centrifugal force introduce the pump as one in which "the mechanical energy is converted, into pressure energy by means of centrifugal force acting on the fluid
