Maglev train

2018-08-02
I believe that the children have played the magnets. The two magnets with the same magnetic poles are put together, and they will pop open. When the different poles are put together, they will attract each other. The mystery of the maglev train is also here. It uses the principle of “same-sex repellent” to install electromagnets on the bogies on both sides of the train. The electromagnets interact with the magnets laid on the rails to generate repulsive forces. When the repulsive force of gravity to reach the train data corresponding equilibrium train to levitate it. i5F strong magnet manufacturers _ Dongguan magnet manufacturers

How do the maglev train start? It does not use an engine to drive the electric motor unlike a normal train. In fact, the drive of a maglev train is exactly the same as the principle of a linear motor. i5F strong magnet manufacturers _ Dongguan magnet manufacturers

The N pole of the electromagnet at the head of the train is attracted by the S pole of the electromagnet mounted on the track at the front point, and at the same time is repelled by the N pole of the electromagnet mounted at a later point on the track. When the train is moving forward, the magnets on the train move with the train, causing the coil or metal plate on the ground to generate an induced current, and the magnetic field of the induced current and the electromagnet on the train to move the train forward. i5F strong magnet manufacturers _ Dongguan magnet manufacturers

Due to the lack of frictional resistance, the maglev train requires very little traction, and the power of several thousand kilowatts can make the train speed reach 550 kilometers per hour. i5F strong magnet manufacturers _ Dongguan magnet manufacturers

When the maglev train decelerates, the change of the magnetic field is reduced, the induced current is also reduced, and the magnetic field is weakened, resulting in a decrease in the suspension force. Therefore, the suspension train is also equipped with a wheel device, and its wheels are like airplanes, and can receive the train in time when traveling. Inside, when you stop, you can put it down and support the train. i5F strong magnet manufacturers _ Dongguan magnet manufacturers

The maglev train has many advantages such as stable operation, no noise, no harmful gas emission, low energy consumption, etc. It is an ideal super special express train in the 21st century. It is believed that in the near future, it will play a big role in people's lives.
