文摘

Interior permanent magnet synchronous motors (IPMSMs) are frequently used in industrial applications because their efficiency and power density are both very high. The IPMSM also makes a very good choice for an electric vehicle or hybrid electric vehicle, because the range of operating speeds is wide enough for use in traction applications. Recently, however, as a result of concerns about there being insufficient supplies of rare earth permanent magnets as well as atmospheric pollution caused by the exhaust gases of automobiles, a need has arisen for motor technologies that require fewer magnets and which can offer a higher level of efficiency. In this paper, we propose a bridgeless IPMSM as a means of reducing the number of permanent magnets used in a motor while simultaneously increasing the power density. The bridge structure, which supports the centrifugal forces generated in a motor’s permanent magnets as the rotor core rotates, was eliminated. To provide support for the separated pole-pieces and permanent magnets, new supporting structures are proposed. As a result, although the air gap torque of the bridgeless IPMSM is almost the same as that of the conventional design, the mass of the permanent magnets can be reduced by 10%.
