This research paper intended to design and build a novel magnetic gearbox system that makes use of permanent magnets and electromagnets to transmit torque between shafts at a variable rate. A magnetic coupling that transfers torque from a single shaft to another without the use of a mechanical connection. The two applications in which electromagnetic shaft couplings are used most often are liquid pumps & propeller systems. This is because a static, tangible obstacle can be placed among the two shafts to split the fluid to the motor working in air. Torque is transmitted by magnet couplings without no mechanical contact. As a result, the mechanical loss is decreased, and if too much torque is applied, damage will be avoided by slippage & mechanically and safely reconnecting. The main benefits include lower maintenance expenses as a result. Additionally, it is possible to lessen the vibration that is transmitted to the equipment, which will increase its lifespan and protect it in the event of an overload. In contrast to current magnetic couplings, this work offers a potential way for the experimental analysis and layout of contactless mechanical energy transmission having variable torque capacity. Using the sketch up programmes, the components of our endeavour were designed, put together, and then the production process was completed. © 2024 Elsevier B.V., All rights reserved.
