Motional Analysis Module

Axial Flux Machine

Axial Flux Machine

The Electromagnetic Motional Module computes time varying fields and eddy currents in devices with rotating or linear movement. Parts of the geometry, and hence the finite element mesh, are allowed to move independently at speeds controlled by the user or calculated as the analysis proceeds. The analysis is a transient analysis, with eddy currents being induced in conducting media both through the effects of the moving magnetic fields, and through the time variation of the model sources.

This module has been designed to include dynamic modelling of all types of electrical machines, for example, including permanent magnet (PM), induction, switched reluctance, synchronous and synchronous reluctance. It can be used to investigate commutation effects, transient responses as well as steady state performance, and unbalanced local effects.

Eddy current losses in all materials, including permanent magnets can also be calculated. Calculations can include the electrical drive under normal and fault conditions and a dynamic mechanical load. At each time-step, the module calculates the electromagnetic force on the moving parts (rotation or translation) and applies an incremental movement followed by recalculation of the electromagnetic fields.
