Hi, 

In transient solver, no. If it is a PM motors, you can simulate it in magnetostatic solver with a "mask" to handle the boundary. Although the matching boundary enforces the periodicity of fields at the boundary edges (or faces in 3D), it does not move the geometry out of the boundary back to the solution domain in the magnetostatic solution. To create a valid partial model for a magnetostatic analysis where the position/angle is going to be swept, the geometry must be fully contained in the periodic sector modeled.

I would still recommend using transient solver and segmented bands (in each time step, rotor should rotate integer number of segments) + mesh operations to improve the accuracy.
