Ansys Maxwell Actuators

Course Overview

The Maxwell Actuators course explores simulation techniques to speed up the design of linear and rotary actuators and solenoids.  The course will guide you through best practices for static and transient parametric studies to optimize actuators, and it will show the benefits of the Distributed Solve Option.  Maxwell Actuators also demonstrates how to set-up multi-domain system models and simulations involving magnetic, mechanical, thermal and circuit simulations. Specific techniques for actuator simulation are explained. These techniques include the mapping of side load forces as a function of eccentricity and airgap length, the calculation of remanent forces due to remanent fields using the Vector Hysteresis Model, and the calculation of forces at zero mechanical air gap. For fast-acting actuators, the course also shows how to include magnetic diffusion in the simulations to accurately predict time-delays in the build-up of flux and current, and hence force.
