| Abstract |
This paper compares inductance calculation methods for IPMSM (Interior Permanent Magnet Synchronous Machine) considering core non-linearity and analyzes electromagnetic performance based on different types of inductance. Inductance is classified into inductance based on matrix, obtained through d-q transformation, and incremental inductance, depending on the calculation method. The torque and output characteristics are analyzed accordingly. By applying motor operating limit conditions, torque and voltage results are compared at the point of maximum torque. The validity of the proposed inductance calculation method is verified by comparing results obtained through finite element analysis. In conclusion, an inductance calculation method that considers core non-linearity while offering superior control simplicity is proposed. |
