In this paper, a novel flux-intensifying flux-controlled permanent magnet motor (FI-FCPMM) is proposed. This motor mainly realizes flux-intensifying (Ld>Lq) and controls the air-gap flux, thus improving the flux-weakening ability and reliability of the motor. This paper analyzes the structure and working principle of the FI-FCPMM, and then makes a performance comparison with the conventional interior permanent magnet motor (CIPMM). The results show that the performance of the FI-FCPMM is better than the CIPMM in control, torque, weak magnetic capacity, noise and constant power output capacity, and it also verifies that the FI-FCPMM has a wider speed range than the CIPMM.
