Magnetic-Geared Permanent Magnet Synchronous Motor for E-Mobility

Thursday, June 30, 2022

Gears and gearboxes are used to vary the speed and torque transmission in various mechanical systems. Despite being traditionally and widely used, mechanical gears suffer from several drawbacks related to friction, heat, noise, and wear/tear; thus, they reduce the efficiency and increase the maintenance cost. In contrast, magnetic gears, free from the above drawbacks, provide higher power density and better protection. Moreover, these contactless gears can be integrated with permanent magnet machines. This novel technology makes the magnetic geared permanent machines a promising solution for direct drive systems. It offers numerous advantages for e-mobility applications such as reduced size and weight, more efficient, low speed, and high torque transmission.

EMWorks’ magnetic solution, for electric machine design and simulation, can be integrated seamlessly in the design and development process of these applications. It helps engineers design more efficient and adaptable geared motors for different e-mobility applications such as electric vehicles, electric scooters, e-trucks, and e-trams.

In this webinar, EMWorks’ solution for magnetic gears will be showcased. We shall show you how you can analyze a magnetic geared PM synchronous motor and explore a rich set of results including, force, torque, back emf, flux linkage, flux density distribution, and more.
