Maglev E-Bicycle

The current trend to produce energy in automobiles/bikes involves the combustion of air-fuel mixture inside a combustion chamber of a reciprocating engine and then converting the chemical energy into mechanical energy in order to perform work. This mechanical energy is then transmitted to the wheel by using power transmission elements. Also there are energy losses involved in transmission of power like frictional losses and damper losses from prime mover to the wheels through different transmission elements. This results in decrease in overall efficiency and increase in fuel consumption in engine. Whereas in maglev wheels, this loss can be lowered to a great extent by running the wheel itself as a prime mover. It is an attempt to run a bicycle with the use of batteries, permanent magnets and electromagnet, so as to develop and manufacture a mode of transport with no fuel consumption and as a results without pollution and environment friendly. Maglev wheels involves the concept of magnetism and use of repulsion property of magnets. The entire wheel of the bicycle consists of permanent magnets. This magnet is attached between the spokes of the bicycle near the wheel rim. These permanent magnets are placed at an equal interval of angular distances held in bracket like structure. Two electromagnets are used to repel this permanent magnet. These electromagnets are placed below the seat of bicycle near and around the both sides of the wheel rim such that permanent magnets and electromagnets are very close to each other with small clearance between them. A solid state relay is used to power the electromagnet. This relay is again powered by small batteries. In order to activate the relay, a proximity sensor is used. This sensor is mounted near the hub of wheel in front of steel lug ring. This ring has slots like those between the gear teeth. The permanent magnets are so arranged that whenever the steel lugs come in front of proximity sensor, one permanent magnet comes in between the two electromagnets mounted near the rim. In this way the output of sensor is transmitted to solid state relay. The relay thus gets activated and allows large voltage and current to pass through it and transmitted it to the electromagnets. The electromagnets having opposite polarity than that of permanent magnets cause the permanent magnets to repel away from electromagnets and the wheel of bicycle starts rotating. This process keeps on repeating as long as steel lug comes in front of proximity sensor and relay is activated.
