Life Cycle Cost:
The life cycle cost(LCC) of an induction motor involves the total purchasing price , installation and operating cost, maintenance and disposal cost of that motor. When used as a tool to compare design alternatives or possible repair, the LCC method show the most effective solution in terms of cost in the range of necessary data is available The constituents of the life cycle cost analysis typically consist initial costs, installation and operation costs, refurbishment and disposal costs. Life Cycle Cost Of An Induction Motor In the field, most of the motors are induction motors. Now-a-days, industry has become more concerned about the performance of the motor. By improving the efficiency of motors we can save energy, reduce operating costs, and improve the End-User Profitability. In case of any failure, motors usually can be rewind, it is often worthy to replace a damaged motor with a new one to save energy and improve reliability.

It is no longer practical to consider the monthly electric bill, such as a fixed basic expenses that cannot be controlled. Energy costs have risen faster than both equipment and good value. They are increasing at a similar level and it is generally possible to pass any increase in power with customers in the form of price increase. Energy prices after the energy crisis has increased faster than the price of the product so as part of a declaration of power that cannot be adopted in one day, which comes directly out of profits. In today's economy, it is more important than ever to keep motor losses under
...and the useful life of the machine should be calculated. Then, depending on the method used, the total cost of the machine is considered as a long term asset and depreciated over the life expectancy of the asset.
In a DC motor, the armature consists of any number of windings, each one an electromagnet. The armature is immersed in a directional external magnetic field. This external field does not move, and can come from permanent magnets or electromagnets.
The fundamentals about rebuilding a twenty-three hundred motor are critical when it comes to rebuilding the motor. The fundamentals tell the builder what they are to aspect and need to know about rebuilding the twenty-three hundred motor. According to Circle Track Magazine “With any engine project, a solid foundation is necessary” is needed when the builder is ready to start building any engine project (“With”). Carley contradicts himself can’t have it both ways. On the one hand, he argues “with any engine project, a solid foundation is necessary” (Jewett). On the other hand, he also says “every engine project starts with the block because the block is the foundation for everything else that follows. (Carley).The builder needs to know that the foundation is going to be a stable and successful process when the builder is finished with the engine project. While doing an engine project is going to be tricky the builder is going to need to know the specific details about how to do the motor. There are numerous types of motors that can be built or rebuilt.
In Internal Combustion Engine Crankshaft play an important role to convert the reciprocating motion of piston in to rotational motion with the help of four link mechanism. Crankshaft is must be strong enough to take the downward force of the power stroked without excessive bending so mostly the life and reliability of engine is depend on the strength of crankshaft. In Internal Combustion engines, the transient load of maximum cylinder gas pressure is transmitted to crankshaft through the connecting rod, However Crankshaft convert reciprocating motion of the piston along with connecting rod to the
Just about 80% of the mechanical power utilized by businesses is given by three stage enlistment engines in view of its basic and tough development, ease, great working attributes, nonappearance of commutator and great speed direction. In three stage enlistment engine the power is exchanged from stator to rotor twisting through acceptance. The Enlistment engine is likewise called offbeat engine as it keeps running at a speed other than the synchronous speed. Like some other electrical engine enlistment engine additionally have two primary parts to be specific rotor and stator. A 3-stage enlistment engine has two principle parts (I) stator and (ii) rotor. The rotor is isolated from the stator by a little air-crevice which ranges from 0.4 mm to 4 mm, contingent upon the force of the engine. The primary body of the Enlistment Engine involves two noteworthy parts as shows in Figure
This involves relating the current supplied to the motor, motor shaft rotational speed, motor efficiency, and the power factor as a function of the load of the motor, similar to the figure on page 21 of the Lab Manual.
Our orthocyclically-wound motor coil makes it possible to manufacture the stator windings with the highest possible copper fill factor, allowing for a shortened motor length while increasing power output by up to 80
Furnaces are designed considering many factors; some of them are efficiency, cost, construction etc. Induction furnace with a 24 pulse converter can solve these problems many industries are now actually facing. Desired temperatures can be attained within no time.
So in this case, a DC motor, two sorts of magnetic(attractive) fluxes are available, ‘armature flux’ and ‘primary
The torque developed by the motor is proportional to the product of the armature of the current and air gap flux i.e.
Induction Motors are widely used in industrial applications. It has been reported that they have a motor market share of approximately 80 percent. Their popularity stems from robust construction, low cost and ease of maintenance.
“AC stands for alternating current, and induction means there’s no physical contact between the rotor and the stator—electricity in the stator generates a rotating
It is asserted that it is essential to fully understand the nature of the load and the user requisite which must be contented by the drive. The load component might or might not have sensors to measure either speed, torque or shaft angle. The sensors which can be used are widely determined by the application. The nature of the load may be translational or rotational and the drive designer must make a judicious choice whether to use a direct-drive with a large motor or geared drive with a smaller but faster one. Moreover, the nature of the load in terms of the need for continuous or recurrent operation must be
The induction motor takes a huge part of the industry, as they are introduced in everyday applications for example, toys, water pumps, fans, washing machines and cars. The reason that the three phase induction motors are very popular is due to the simplicity of the mechanisms included, low cost availability, low risk of failure, economical and can produce large torques. Other reason that the three phase induction motor is widely used is that it can be easily handled and easily fabricated to suit all kinds of applications, the three phase induction motors can be manipulated to produce high or low torques and high or low speeds.
Opportunity cost the loss of possible profit from other substitutes when another substitute is selected. Opportunity cost applies to the options we have, so concerning the necessities of life and what we desire. Humans require certain necessities to live like food, water, and shelter, but things like gaming systems or expensive jewelry are the materialistic things we still longing for. Nowadays it is uncommon for people to save until they retire and not spend any money within that time for their own personal use, so then we are expected to indulge once in a while. On occasion and not within budgeting extremes treating yourself and your family is called for. Opportunity cost is utilized to comprehend the practical use of what is purchased versus
