Investigation of the Influence of the Geometric Dimensions of Permanent Magnets on the Magnitude of the Back Electromotive Force in Synchronous Machines with Sensorless Control

The current publication examines how the geometric parameters of permanent magnets in electric motors with permanent magnets affect the back electromotive force (EMF). Understanding this reverse EMF is crucial for regulating the motor's dynamics based on magnet properties. Investigating the influence of magnet geometry on the reverse EMF and motor speed is crucial in light of rapid advances in electric drive technologies. With new materials and design approaches emerging, there is a need to better understand how magnet parameters affect motor characteristics. By systematically modifying the magnet's geometric parameters, we aim to identify specific changes that cause variations in the reverse EMF and motor speed. This study is valuable for developing efficient electric drives that meet performance standards. Consequently, our article focuses on exploring the relationship between magnet geometry, reverse EMF, and motor speed. We anticipate that the findings will enhance understanding of how magnet parameters impact electric motor performance and contribute to the development of more efficient drive systems.
