Reduction of permanent magnet materials in electric machines is of interest to many machine manufacturers and designers as cost of rare-earth materials is of increasing concern. The impact of changing a machine design parameter, such as the shape of the magnets, may have consequences such as a reduction in efficiency, or introduce a change in torque quality. In this paper, an efficiency map computation...
The paper proposes a study of synchronization capability of line-start permanent magnet synchronous motor with small saliency ratio and very high cage resistance. The exemplified method is for a motor with the rated power of 3.5 kW, the synchronous speed of 3000 rpm, and the saliency ratio of 1.08.
The present and future market for motors places high value on power density, operating efficiency, reliability, variable speed operation and low cost. Permanent magnet (PM) motors are now able to meet these market expectations. Compared to the prolific induction motor, PM motors provide the attributes of efficiency and reliability, plus have the additional advantages of higher power density (power...
The present and future market for motors places a high value on operating efficiency, reliability, variable-speed operation, low running temperature, quiet operation, and low cost. Permanent-magnet (PM) motors are now able to meet these market expectations across an increasing range of ratings. Compared to the prolific induction motor, PM motors provide the attributes of efficiency, reliability, etc...
