Including Remanence into Electromagnetic Models of Solenoid-Type Actuators

For the advancement of modern mobility solutions, ranging from 2-speed BEV transmissions and hybrid systems to commercial vehicles, precise control of electromagnetic actuators is essential. Because automotive powertrains utilize structural or case-hardened steels for their mechanical strength, these materials introduce distinct magnetic challenges (high coercivity) and significant remanence forces that are often overlooked in standard simulation models.

This project focuses on extending electromagnetic modeling to include detailed hysteresis behavior. The goal is to accurately simulate dynamic operating characteristics by accounting for environmental factors such as mechanical vibration and temperature. By precisely predicting holding forces and defining optimal demagnetization pulses, the project delivers a validated framework for ensuring robust actuator operation, applicable across a wide spectrum of mobility platforms.
