Transient 3D with Motion --
New solver provides accuracy every step of the way

Montréal, Québec, Canada – February 12, 2004 -- After months of anticipation, Infolytica is pleased to announce that the Transient 3D with Motion solver is finally here. This latest addition to MagNet's impressive list of solvers represents the culmination of several years of research. With this new solver, the field equations are solved in 3-dimensions and include motional effects. It is now possible to analyze moving devices having no translational or axial symmetry. Examples include electric machines with skewed slots; devices where the winding end effects are important; and linear motors with long secondaries. Users familiar with our 2D version of this solver will find the same easy-to-use and powerful analysis tools that allow you to get the results you need. Infolytica's advanced T-Omega formulation, which features the hierarchical element method (based on polynomial orders 1 to 3), and the edge-based formulation are both incorporated in MagNet 6.14.

Key features

coupling to the mechanical equations of motion

• accurately simulates the movement of a component of a device
  (e.g. the rotor in an electrical machine or the plunger in an actuator).

mechanical effects

• viscous friction
• inertia
• mass
• springs
• gravitation
• constraints on movement imposed by mechanical end stops
• arbitrary load forces specified as a function of position, speed, and time

Re-mesh regions

• A distinct advantage that Infolytica's motion solvers enjoy over any of our competitors is our utilization of the re-meshing method as opposed to the sliding surfaces method. One of the many benefits of using the re-mesh method is that usually only the region surrounding the motion component is re-meshed, resulting in just a small computational expense. Other Electromagnetics Design Software companies use the sliding surfaces method, which can add a major computational expense at the solution stage.

Typical applications for the Transient 3D with Motion solver include electrical machines (claw-pole, induction motors, switched reluctance, brushed and brushless DC), actuators, levitation systems, braking systems, magnetic bearings, loudspeakers, and electromechanical shakers.

Keep an eye on our Gallery section as the coming weeks will provide various examples of the Transient 3D with Motion solver in action.
