In this study, a new double‐rotor permanent magnet vernier induction wind generator is proposed, which can be connected directly to a double‐turbine system used in urban areas. The proposed generator consists of a vernier machine and a squirrel‐cage induction machine, which includes a stator and two concentric rotors (a permanent magnet outer rotor and a squirrel‐cage inner one). Accordingly, first, the relationships governing the structures of each rotor are presented and investigated. Then, the performance of the generator connecting to a double‐turbine system is analysed. Optimisation of the presented generator is investigated by finite‐element analysis and also a laboratory prototype is constructed. Finally, both simulation and experimental results are compared, and the reliability of the proposed generator is validated.
