A pull-back motor car is one of the most common toys available on the market. We pull it backwards and then let it go. It travels across almost the entire room before stopping. We pull it back just a few inches, but the distance traveled by the car is 8-12 feet. Have you ever wondered how that happens? Well, todayRead More
Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of …

An electric motor is a device that converts electrical energy into mechanical energy. It works on the principle of electromagnetic induction, which states that a changing magnetic field can induce an electric current in a wire. Electric motors have three main components: a rotor, a stator, and a commutator. The rotor is the rotating part …

An electric motor is a device used to convert electricity into mechanical energy —opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field. This force creates a torque on a loop of wire present in the magnetic field, which ...

Here is a step-by-step breakdown of what happens with a DC-coupled system: Sunlight hits the solar panels and the energy is converted to DC electricity. The electricity enters the battery and is stored as DC electricity. The DC electricity then leaves the battery and enters an inverter to be converted into AC electricity the home can use.
A new structure of dual-rotor electromagnetic coupling energy-storage motor (ECESM) is presented to output transient high power under low excitation power. Its mechanical structure and working principle based on eddy effect are explained and the transient equivalent circuit is derived.
Abstract. Energy consumption in the world has increased significantly over the past 20 years. In 2008, worldwide energy consumption was reported as 142,270 TWh [1], in contrast to 54,282 TWh in 1973; [2] this represents an increase of 262%. The surge in demand could be attributed to the growth of population and industrialization over …

The huge rotor blades on the front of a wind turbine are the "turbine" part. The blades have a special curved shape, similar to the airfoil wings on a plane. When wind blows past a plane''s wings, it moves them upward with a force we call lift; when it blows past a turbine''s blades, it spins them around instead.
Video signals occupy a much wider bandwidth than do audio signals and require a much higher relative speed between the tape and the head. Data recording requires even greater speeds. The tape transport of a data-storage unit of a high-performance digital computer, for example, must be able to move the tape past the head at a rate of 200 in. (500 cm) …
