To solve the problems of high cost and high waveform deviation factor of the electromotive force (EMF) of the rare earth permanent magnet (REPM) generator for extended‐range electric vehicle (EREV), a consequent‐pole REPM generator is proposed. Based on the model of the conventional 18‐slot/12‐pole REPM generator for the range extender, three models are proposed, and the optimized model of REPM generator is obtained by optimizing the rotor structure. Finite element software is used for simulation analysis. The results show that the amplitude of the fundamental wave of EMF of the optimized REPM generator model accounts for 93.7% of that of the conventional model, the waveform deviation factor of EMF accounts for 35.8% of that of the conventional model, and the amount of REPM materials accounts for merely 55.2% of that of the conventional model. Finally, the rationality of the design of the consequent‐pole REPM generator for the range extender is verified by experiments. © 2019 Institute of Electrical Engineers of Japan.
