Basic Introduction or Principle: We all are aware with the term "Generator". A device which converts mechanical energy into electrical energy is known as generator. This generator makes rotate with the help of some kind of external energy. When this energy extract from the energy of steam, the plant is known as steam power plant.  A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a  boiler   which converts it into high pressurized super heated steam. This high energized steam passes through steam  turbine  (a mechanical device which converts flow energy of fluid into mechanical energy) and rotate it. Owing to extract full energy of steam, three stage turbines is used which is known as LPT (Low pressure turbine), IPT (intermediate pressure turbine) and HPT (High pressure turbine). The turbine shaft is connected to the...

2 Wheeler scooters are an efficient and favorite transportation medium among children and people. We here propose a motorized 2 wheel scooter to make it an e scooter. 2 Wheeler mini scooters are light weight, easily foldable and to carry around. For this purpose we here use a motorized arrangement to couple the scooter wheel with a motor so motor power can be utilized to move the scooter as its engine. For this purpose we use a shaft designed for our dc motor. We then use a gear arrangement to mount it to the back wheel of the scooter. We now mount the gear of the motor in a particular arrangement with the wheel gear so as to transfer the maximum torque of the motor to the wheel without jerks. We now use control circuitry to drive the motor at variable speed so we can control the scooter speed using a remote that can be mounted on the scooter handle. We use a battery to drive the motor and circuitry. Thus we develop a motorized scooter running on electricity for intercity travel. ...

Here we propose the design and fabrication of a fully automated paper cutter based on geneva mechanism. Our proposed system cuts paper pieces of equal lengths based on geneva mechanism. System uses a 12V motor in order to drive the entire system. We use a shaft which is directly connected to the motor. This shaft has a connecting rod which is connected to a scissor in order to drive the cutting mechanism for cutting paper. This motor shaft is connected to a sprocket which is in turn connected by a chain to another sprocket. This sprocket is now connected to a genava mechanism wheel. This wheel is used to drive paper feed into the cutter mechanism. Here we use geneva mechanism driven by another connecting z shape rod. This mechanism ensures paper feed of equal length inserted at proper time intervals. System uses a supporting frame that maintains proper coordination between feed and cutting mechanism. Components 12V motor Shaft Sprockets Chain Connecting Rod Geneva W...

Electromagnetic Braking System Electromagnetic braking means applying brakes using electronic and magnetic power. Here we use the principle of electromagnetism to achieve friction less braking. This tends to increase the life span and reliability of brakes since no friction leads to less wearing out of brakes. Also it requires less maintenance and oiling. This is an upcoming technological replacement for traditional braking systems. The main purpose behind the proposed use of these brakes in vehicles is that it is frictionless. This leads to a sizably less maintenance cost due to no friction and no oiling. Also traditional braking systems are prone to slipping while this one is guaranteed to apply brakes to the vehicle. So without friction or need of lubrication this technology is a preferred replacement for traditional braking. Also it is quite smaller in size compared to the traditional braking systems. To make electromagnetic brakes work, a magnetic flux when passed in a dir...

Today we will learn about lathe machine parts, its operation and working. Lathe machine is a basic machine which is used in every metal forming industries. It is combination of many parts which works together to perform a desire function. A lathe machine is used to machine cylindrical work piece which is 360 degree symmetrical form the axis of rotation. It used to perform turning, chamfering, boring, facing, internal threading, shaping, slot cutting etc. on cylindrical work piece. There are many types of lathe machine but each machine consist some basic part which are essential for its proper working. These parts are bed, tool post, Chuck, head stock, t ail  stock, legs, Gear chain, lead screw, carriage, cross slide, split nut, apron, chip pan, guide ways etc. These parts work together to obtain desire motion of tool and work piece so it can be machined.  The lathe machine works on basic principle that when the work piece rotate at a constant speed and a tool is in...
