We derive a shortcut stationary metric formula for generati ng imperfect fluid rotating solutions, in BoyerLindquist coordinates, from spherically symmetric static ones. We explore the properties of the curvature scalar and stress-energy tensor for all types of rotating regular s olutions we can generate without restricting ourselves to specific examples of regular solutions (regular black holes r wormholes). We show through examples how it is generally possible to generate an imperfect fluid regular ro tating solution via radial coordinate transformations. We derive rotating wormholes that are modeled as imperfect fl uids and discuss their physical properties that are independent on the way the stress-energy tensor is inter pre d. A solution modeling an imperfect fluid rotating loop black hole is briefly discussed. We then specia lize to the recently discussed stable exotic dust Ellis wormhole emerged in a source-free radial electric or magnet ic fi ld, generate its, conjecturally stable, rotating counterpart which turns out to be an exotic imperfect fluid wo rmhole and determine the stress-energy tensor of both the imperfect fluid and the electric or magnetic field.
