1. Actuation systems can exhibit complex dynamic behaviour 2. Cannot consider electromagnetic system in isolation 3. Electromagnetic aspects sometimes the easiest to model 4. Required degree of coupling required depends on relative time-constants 5. De-coupled' formulation has advantages: 5.1 implemented using commercial packages 5.2 computationally efficient 6. However, cannot account for dynamic effects e.g. eddy currents.
