A magnetic coupling is a device that transmits torque between two shafts via a magnetic field, eliminating the need for a physical mechanical connection. This technology is widely used in various propulsion systems, such as vehicles and remotely operated underwater vehicles, to transfer torque from electric motors to propellers.

ELIX Wireless employs Magneto Dynamic Coupling (MDC) technology, which integrates rotating magnets with a built-in motor generator system for wireless power transfer.

A similar technology is showcased by the WiPASS Magnetodynamic Wireless Power Transfer (WPT) system. This system features a transmitter that generates a time-varying magnetic field, while the receiver consists of a magnet that moves within a coil. The changing magnetic field produced by the transmitter applies a force or torque on the magnet, causing it to move or rotate.

Blockchain Technology

👉 Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system.

👉 A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

👉 Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger.

👉 The decentralised database managed by multiple participants is known as Distributed Ledger Technology (DLT).

👉Voltage and Current Values in Three-Phase Systems 👍👏

🔋🔌When we measure voltage and current in three-phase systems, we need to be specific as to where we’re measuring.

🔋🔌Line voltage refers to the amount of voltage measured between any two line conductors in a balanced three-phase system. With the above circuit, the line voltage is roughly 208 volts.

🔋🔌Phase voltage refers to the voltage measured across any one component (source winding or load impedance) in a balanced three-phase source or load.

🔋🚦🔌For the circuit shown above, the phase voltage is 120 volts. The terms line current and phase current follows the same logic: the former referring to the current through any one line conductor, and the latter to the current through any one component🔥

🔋👉🔌Y-connected sources and loads always have line voltages greater than phase voltages, and line currents equal to phase currents. If the Y-connected source or load is balanced, the line voltage will be equal to the phase voltage times the square root of 3.👍👏🔥🔥
