Field-Network Simulation of Dynamic Characteristics of PM LSMs

In order to understand the behavior of an electromagnetic system, it is important to comprehend the dynamics of its components.

There are several basic methods of formulating the equations of motion and thereby obtaining the characteristics of the electromagnetic energy conversion devices. These are through the applications of [145, 238]

• electromagnetic field theory;

• principle of virtual work;

• variational principles.

Each of the above approaches has its own merits and, in some cases, one cannot be conveniently substituted by the other [209, 225].

Mechanical and electrical parameters of the system are necessary to formulate the equations of motion. Electrical parameters ...
