Parameter Design Method of PMSM Based on 2-Dimentional Key Variable Plane

Performances of permanent magnet synchronous machines, such as torque, power and field-weakening capability are determined by the machine parameters. It is difficult to choose proper parameters to fullfill the performance requirement, because it is a multi-input & multi-output process. This paper proposes a new parameter design method, which is based on 2-dimentional key variable plane. It helps choose the best value of key variables by plotting contour maps of the performance targets on the key variable plane. Then, machine parameters can be calculated from the key variables. The proposed method is capable of optimizing both the rated current and the maximum current. Moreover, it is simple to be implemented.
