In this paper, a permanent magnet assisted synchronous reluctance machine (PMASRM) with optimized permanent magnet width and asymmetric rotor structure is proposed. A typical PMASRM is selected as the reference motor (Pre-optimized PMASRM). In order to reduce the large torque ripple of conventional PMASRM, an optimization method to design the permanent magnet width is investigated and the Optimized Magnet-width PMASRM is proposed. On this basis, an asymmetric flux barriers structure is proposed to further reduce the torque ripple. Some electromagnetic characteristics including air-gap flux density, no-load back EMF and motor efficiency are examined by Finite Element Analysis (FEA). The simulation results show that the proposed PMASRM can not only decrease the harmonic component of no-load back EMF obviously, but also reduce the torque ripple in steady-state operation, which proves the rationality of the motor structure.
