Electricity War

By comparing the power generation of two types of generators, understand the working principles of different types of generators. The exhibit consists of a steel structure booth, organic glass cover, rotating generator model, linear generator model, rotating handwheel, push-pull handle assembly, LED lights, etc. Two different types of generator models are set up on the steel structure exhibit platform, one is a linear generator and the other is a rotating generator. This exhibit requires two visitors to challenge simultaneously, pushing and pulling the handle of a linear generator and the handwheel of a rotating generator to compare the number and brightness of the LED lights driven by the two generators. The linear generator controls the horizontal movement of the magnet to cut magnetic field lines and generate electricity by horizontally reciprocating the push-pull handle, while the rotating generator can rotate the magnet to cut magnetic field lines and generate electricity by rotating the handwheel. Target audience: Adolescents aged 6-15 years old. Presentation format: Mechatronics.

Interaction type: Electromechanical interactive. The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The working principle of a generator is mainly based on the law of electromagnetic induction. It is composed of components such as stator, rotor, end cover, and bearings. The stator and rotor of the generator are connected and assembled through bearings and end covers, allowing the rotor to rotate in the stator. A certain excitation current is passed through the over-current ring, making the rotor a rotating magnetic field. The stator coil cuts the magnetic field lines, generating an induced potential, which is led out through the terminal block and connected to the circuit to generate current. Reference materials.
