What is a homopolar engine?

Homopolar motor is a device that converts a magnetic field and direct electric current (DC). The main parts are a permanent magnet with a neighboring metal disc and a shaft; Homopolar means that there is only one pole or the side of the magnet next to the rotor. The direct current is applied to the disk and rotates due to the effects of the current passing through the magnetic field. Scientist Michael Faraday first demonstrated the effect in 1821 to rotate the wire around the magnet in the mercury bath. The rotating disk creates a DC current that can be stored in the battery. Although this principle is not practical for a large generation device, one pole generator can be useful when DC current is needed. Mathematician Peter Barlow developed a bike in 1822 at the demonstration Faraday Effect. The Barlow wheel uses a rotating metal disk connected to the battery and suspended above the tray or the riverbed surrounded by a permanent magnet. When the rotating disc is reduced to the mercury and the electrical circuit is completed, the current interacts with the magnetic field and turns to theOLO.

One of the advantages of one -pole engine technology is to reduce parts. Motors with wire coil stator and rotor must also use the commutator for proper operation. Komutator is a device that turns the engine polarity when rotating rotates. This is necessary because the rotor changes the position in the motor magnetic field and the polarity change is necessary to ensure a torque or rotating force.

There are a number of practical applications for homopolar engine. The boat drive began to use these engines in the 20th century, with electric discs replacing the diesel engines connected to the drive shaft passing through the ship's fuselage. Electric generators can produce DC power supply for systems connected directly to the propeller.

From the beginning of the 21st century, the electrical units were installed in the rotating pods under the nave, which can provide a thrust in any direction. This technology provides a good ÚDrive activity and provides excellent ships for docking and maneuvering. The bridge can be dominated from the Joystick Bridge bridge and eliminate driving shafts with their maintenance and potential leakage problems.

technology studied on various devices since the 17th century is a linear acceleration, known in the development of weapons as a railway weapon. Linear accelerators use Faraday's engine principles by energizing the dual rail with electricity. The metal sled or projectile rests on the upper part of the rails, while the current passes through the sled from one rail to another. The resulting effect is the homopolar engine. Rather than rotting, however, a sled or projectile is driven when raising speeds along the rail.
