“…Consequently, high torque and wide speed range can be achieved by controlling the current pulse [13]. In [14], mechanical-variable-flux PM machines (MVF-PMMs) are presented and studied, where the mechanical flux-adjusting device is attached to the rotor. Compared with electrical variable flux techniques, MVF-PMM has the advantage that the magnetic field can be adjusted flexibly by the equipped mechanical flux-adjusting device [15].…”

This paper presents a novel variable leakage flux flux-intensifying motor (VLF-FIM) to improve flux-weakening ability. The innovation lies in the variable leakage flux property and the characteristic of L d > L q . The two characteristics can be achieved by the adoption of magnetic barriers and magnetic bridges. Consequently, the flux-weakening ability is enhanced. Then, the topology structure and operation principle of the proposed machine are introduced. Based on the two-dimensional finite element method (2DFEM), the performances of the proposed motor are analyzed and compared with the conventional interior permanent magnet motor (CIPMM) in detail. The performances mainly include torque, flux-weakening ability, constant power speed range (CPSR), irreversible demagnetization risk of the PM, structural strength, etc. Finally, the results show that the proposed motor has some advantages, such as good flux-weakening ability, a wide constant power range, and a large high-efficiency area. In addition, it verifies the effectiveness of the proposed method in improving the flux-weakening ability of the motor.
