This paper is all about a design, construction, and analysis of permanent magnetic gears. The basic idea of a gearing is to convert mechanical power from one rotational speed and torque to another speed and torque. The input power that is used in most of the applications is with small revolution speed and great torque. But many applications require input power with less revolution speed and great torque. The problem is often lack of torque from the source drives. The physical size of a direct drive electrical machine able to drive a conveyer belt directly will typically be too large and expensive. A more cost-effective solution will be to place a transmission between the conveyer belt and the electrical machine. Mechanical gears are often used for such transmission purposes. The magnetic gears designed particularly for the transmission and automobile sectors, with comparison with non-magnetic gears. After completing primary design, detailed calculation is done followed by CAD modeling and analysis at the end. In increasing productivity, this can show better results. © 2021, Springer Nature Singapore Pte Ltd.
