Vane motor report
This document describes a student project to design and build a vane air motor. A vane air motor uses compressed air to power rotation of a slotted rotor containing sliding vanes. As the high-pressure air enters, the differential force across each vane causes the rotor to turn. The students customized a vane motor using plywood, wood, and a hand pump air supply. They provide details on the components and operation of a typical vane motor as well as references used in their project design.

- 3. Abstract- It isnow a fact that the environment is being subjected to plenty of environmental hazards. These are attributable to pollution that has completely overwhelmed the environment. It is also responsible for bringing about atrocious changes to the environment. The principle reason behind this change is increased carbon emission. Every day, a huge amount of carbon is released in the air because of burning fuel which results in Global Warming. People are gradually realizing this concern and have gradually started to use alternative sources of energy. This project about a design of a motor that runs on compressed air. Vane Air Motors contain vanes within an air tight body onto which air at high pressure is passed. The vanes are directly connected to a rotating shaft and hence any force on the vanes causes a torque, which can rotate the shaft helping to drive any load connected to it. Not only does this solve an age old question of finding an energy efficient fuel source, it also proves that efficient fuel can also be environment friendly.

While energy surrounds us in all aspects of life, the ability to harness it and use it for constructive purposes as economically as possible is the challenge before mankind. The burning of all kinds of fuel exhausts carbon dioxide gas. This gas together with other exhaust gases causes severe air pollution. Moreover, the fuels commonly used today (fossil fuels) are all limited such that as more fuel is consumed natural resources are decreasing. There has been a steady movement towards developing higher fuel efficient machines and more contraptions based on alternative energy sources for consumers. In response, many smaller companies have started to rapidly increase research and development into radically different ways of powering consumer Vehicles. Alternative energy refers to energy sources which are not based on burning of fossil fuels or the splitting of atoms. The renewed interest in this field of study comes from the undesirable effects of pollution (as witnessed today) both from burning fossil fuels and from nuclear waste. Among the renewable energy resources found so far the use of compressed air for storing energy is a method that is not only efficient and clean, but also economical. Compressed air is also used to run vehicles such as cars. The power source of these kinds of cars is air and the emission product is also air. Cars using compressed air can travel 120 miles between refueling. The cost to operate is low. The compressed air only car will need to go to compressed air fueling stations for a compressed air refill. Once these retrofitted gas stations are in place, a refueling will take 3 minutes. Alternatively, there are engines being developed that either switch over to electric or gas power allowing the car to continue to be driven, while at the same time operating the compressor to refill the tank with compressed air.

A motor boat runs its fan to push fluid in a direction opposite to its desired motion, whereas the vane air motor pushes air (fluid) on its vanes to create rotational motion of its drive shaft. As highly compressed air is ejected from the high pressure air tank into the air inlet valve of the air motor it induces a force on the vane it first encounters. A typical vane-type air motor is shown in figure. The rotating element is a slotted rotor which is mounted on a drive shaft. Each slot of the rotor is fitted with a freely sliding rectangular vane. The rotor and vanes are enclosed in the housing, the inner surface of which is offset from the drive shaft axis. When the rotor is in motion, the vanes tend to slide outward due to centrifugal force. The distance the vanes slide is limited by the shape of the rotor housing. This motor operates on the principle of differential areas. When compressed air is directed into the inlet port, its pressure is exerted equally in all directions. Since area A is greater than area B, the force exerted on vane at position No.1 is more than the force exerted on the vane at position No.2. Hence the rotor will turn counterclockwise. Each vane, in turn, assumes the No.1 and No.2 positions and the rotor turns continuously. The potential energy of the compressed air is thus

- 7. Components of VaneMotor: Slotted Rotor: It is the rotating element of the vane moor. It is mounted on a drive shaft. It has slots to accommodate the freely sliding vanes. Vanes: These are usually rectangular. Vanes help maintain air columns inside the motor housing. Due to the difference in the forces acting on the vane surfaces the motor rotates. Motor Housing: It is hollow cylinder in which the rotor and vanes are kept. The center of rotor is offset with the housing. It has ports for inlet and outlet of air. The inlet port is at the place where the rotor is nearest to the housing. Outlet port is usually diametrically opposite.
