A new method to solve the 3D transient electromagnetic field-circuit-torque coupled problem

A new method to solve the 3D transient electromagnetic field-circuit-torque coupled problem is described, in which the external circuits, nonlinear magnetic properties, eddy-current effects and movement are taken into account. The transient 3D magnetic field circuit coupled problems are solved by the Crank-Nicholson method, and the problem of motion is handled by the interpolation movement interface method which is a new kind of nonconforming movement technique. The method has been applied to analysis the model of TEAM Problem 24 and its advantages are demonstrated.
