Plasma rotation and radial electric field in the presence of resonant magnetic perturbations (RMPs) is considered. The situation is discussed in detail where no change of poloidal rotation is observed while the radial electric field and toroidal rotation are changing self-consistently when RMPs are switched on. Recent experimental results from DIII-D are discussed in connection with this model.
